Publisher’s Letter

IoT or Internet of Things is no longer a new phrase to us. However, we are yet to taste the amazing benefits that can be obtained from application of the technology. Let us see a recent example, where

using IoT – battery monitoring in railways can be made drastically easy. Saft is globally well known for its design, development and manufacture of high technology batteries for industry. In September 2016, during InnoTrans 2016, the company launched its groundbreaking battery monitoring solution: C.O.M.M. Batt. This is the first ever IoT service for nickel-based onboard batteries.Targeted initially for railways, the company’s new service will now enable rail operators to realize the benefits of predictive maintenance planning – for their backup batteries – based on remote, real-time monitoring – e.g., reduced downtime, optimised fleet management and the associated cost efficiencies. With a view to further improving Life-Cycle Costs (LCC) and maintenance intervals for the nickel-based batteries, Saft has developed the C.O.M.M. Batt service as an innovative element within its global improvement program. To describe the technology in short: C.O.M.M. Batt uses a wireless technology to transmit a wealth of diagnostic data. This data is analyzed using Saft’s advanced modeling algorithms based on real-world knowledge drawn from a vast installed base to provide information on battery operation and charge condition as well as key predictive facts on maintenance. Thus, it empowers the operator to see a real-time picture of how the batteries are performing. He or she can access this information on a PC or a smart phone and receive message alerts.Those who have experience of battery management, they easily understand how cumbersome the physical monitoring process is… When we look at the benefits of the technology, it indicates some significant advantages. According to a communiqué from Saft, “C.O.M.M. Batt provides an effective basis for a transition to a predictive maintenance regime, rather than corrective and preventive maintenance, which yields other benefits such as lower maintenance costs and, increased fleet availability. C.O.M.M. Batt represents a flexible philosophy that can be adapted to suit specific train equipment, communication protocols and operator maintenance workflows.”Thus, IoT is soon going to break the boredom of the battery operators’ job.

There is no doubt that it’s a matter of pride and great pleasure for all the citizens of India that we are about to generate 6,780 MWe from nuclear sources. Yes, the 2nd Unit of Kudankulam Nuclear Power Project (KKNPP – 2), i.e., India’s 22nd Nuclear Power Reactor has attained

criticality on July 10, 2016 at 20:56 hrs. The unit is operating at 245 MW now, and it has been synchronised with the Southern Grid on 29 08 2016 at 11:17 hrs. Gradually, following the laid-down procedures and in line with the stage-wise regulatory clearances accorded by the Atomic Energy Regulatory Board (AERB), its power will be raised in steps to cent per cent, i.e., 1,000 MW. KKNPP – 1&2 are (2X1000 MW) are the largest size electricity generating units in the country. These VVER – 1000 type light water reactors have been set up in technical co-operation with the Russian Federation in the first phase. According to the plan, the Kudankulam site will host six reactors all together. The excavation for the second phase of KKNPP consisting of two reactors (2 X 1,000 MW) has commenced.

However, as far as nuclear energy is concerned, several questions are still hovering around it. Although, owing to its very low carbon footprint, the nuclear energy is called a form of clean energy; creating replicas of Yucca Mountains (USA) in India for nuclear waste disposal is not a very well accepted solution. Moreover, if we recall the chemical explosion in 2014 in the Waste Isolation Pilot Plant, (under construction) in the USA that actually contains nuclear waste, we can’t find a justification for the proposed deep geological repository in crystalline rock near Kalpakkam. The US government renewed its contract with dump operator Nuclear Waste Partnership to the tune of $640 million extra just for cleanup of the site.

Also, there is debate on the fact whether nuclear energy is a renewable one or not. The apparent relation between the sun and the earth is expected to continue for the next 5 billion years. As per Bernard L Cohen, former Professor, University of Pittsburg, using breeder reactors (nuclear reactors able to generate more fissile material than they consume) it is possible to fuel the earth with nuclear energy indefinitely. So, it is sustainable like the solar energy, and falls under the renewable category.

Still considering the challenges associated with the nuclear waste disposal and the never-ending risk factors linked to it, I feel when we have so much opportunity to harness solar and wind energy; we are supposed to put more attention on them.

GoI revives stranded gas-based power generation plants through e-auction

According to the available information from sources, the Government of India has revived nine stranded gas-based

power generation plants with an installed capacity of 5,070 MW, which successfully bid through a transparent and competitive reverse e-auction process.

This was made in the fourth phase of reverse e-auction for the stranded gas-based plants conducted under scheme for utilisation of stranded gas-based generation capacity.

These plants will generate 8.81 billion units of electricity, which will be supplied at or below Rs 4.70 per unit to the purchaser Discoms during the period from 1st October 2016 to 31st March 2017. This will involve government support of Rs. 187.14 crore from the Power System Development Fund.

The auction process concluded on September 3, 2016 wherein nine plants emerged as preferred bidders and were

allocated 9.93 MMSCMD e-bid RLNG. The present reverse e-auction for the stranded gas-based plants is the fourth phase of auctions conducted under Scheme for Utilisation of Stranded Gas Based Generation Capacity.

The grid connected gas based power generation capacity in the country is 24,150 MW. Of this, a capacity of 14,305 MW had no supply of domestic gas. These comprise 29 plants, which were eligible to participate in the auction process. 14 plants with a cumulative installed capacity of 7575 MW participated in the auction process for Phase IV.

The successful bidders include power plants in Southern region. The generation from these plants would improve the power availability in the Southern grid, mitigating to a large extent the shortage of availability and constraint of evacuating the power to the Southern region from other regions.

Uttarakhand’s 100MW solar project’s work is on

NTPC, IIT Madras sign MoU

NTPC and IIT Madras have signed a Memorandum of Understanding (MoU)

for Research and Development (R&D) in the areas of mutual interest such as bulk ash utilisation, carbon capture, waste to energy, gypsum building, under water imaging, DC

grid system, DC light, grid stability, intelligent controllers, combustion and nanotechnology in New Delhi.

As per the MoU, joint R&D projects will be taken up by both the organisations for development of new technologies, process and

product for optimisation and efficiency improvements etc.

The MoU was signed by R K Srivastava, Executive Director, NTPC-NETRA, and Prof. Krishnan Balasubramanian, Dean (IC&SR), IIT Madras.

The execution of the 100 MW Solar Power Project in Uttarakhand, which is being

handled by Rays Power Infra, has begun in August, 2016; and it is expected to be commissioned by February, 2017.

It will be executed by the company on turnkey basis – from land acquisition to commissioning.

Moreover, instead of forcing farmers to sell their lands, the company has devised a unique model where farmers can also become a part of the project, and as a result, will enable the solar

company to acquire 500 acres of land in such a difficult terrain.

The 100 MW project is spread over a sprawling land area in Tehsil-Bhagwanpur in the Roorkee District of Uttarakhand. It comes under Uttarakhand Renewable Energy Development Agency’s (UREDA) competitive bidding for 2015-16.

Pawan Sharma, Director-Projects, Rays Power Infra, said, “After successfully commissioning a 55 MW Solar Power PV project in UP, this 100 MW project in Uttarakhand will be

our biggest project, adding another remarkable milestone to Rays’ list of executed projects.”

“Rays Power Infra is following a co-development model, i.e., we have got the necessary permission from all local authorities, and are also working with foreign investors. Since this is a

mega-sized project and will require lot of land area, farmers will be getting a recurring rental income for more than 25 years by leasing their lands,” he further added.

Tata Power Renewable Energy Limited acquires WREPL

Tata Power Renewable Energy Limited (TPREL) has recently completed acquisition of 100% shareholding in

Solar energy has almost doubled its total installed capacity over the last one year and the pace of growth is set to increase further,

with gigawatts of solar capacity being tendered by the government...

India is making rapid strides in the renewable energy space, as part of its global climate change commitments. The country has pledged to achieve 175 GW of renewable energy generation capacity by 2022, out

of which approximately 100 GW will be from solar power installations alone. Given its clean nature and increasing affordability, solar energy is gradually gaining popularity around the globe. With millions of its citizens still living in darkness, India needs to increase its electricity generating capacity substantially. Not only is solar energy green, but is also becoming one of the cheapest energy options.

Indian solar energy landscapeSolar energy has almost doubled its total installed capacity over the

last one year and the pace of growth is set to increase further, with gigawatts of solar capacity being tendered by the government. Not only are the local players benefiting from the growth of solar in the country, but many large foreign players are also eyeing this as an excellent opportunity to expand their footprint in India. Solar energy has become highly competitive, with solar prices ranging between around INR 4.5-5.5 per unit these days. This makes it much cheaper than gas based power and almost equal to imported coal power. With storage costs expected to fall in the future, it will be possible for people to become completely independent of the power grid in the near future.

Total installed capacity has already touched more than 8 GW in India. The leading Indian states are Tamil Nadu, Rajasthan and Gujarat which have already installed more than 1 GW of solar power as of today.

Strong support from the Central government has paved the way for solar to succeed in India. The government increased the subsidy levels for rooftop solar to promote the same. Solar water pumps and solar lights are

also increasingly being used in the country especially in remote areas, with no grid connectivity. Our Prime Minister Narendra Modi made a strong commitment of India’s green credentials in the Paris summit and has been instrumental in forming the International Solar Alliance (ISA).

Key components of a solar PV system

A typical solar system consists of solar panels or modules, inverter and balance of system like wires, cabling, mounting structures, junction boxes etc. A typical solar system could be a rooftop solar system or a ground mounted solar system. The latter is more prevalent in

India. The growth in solar rooftop market has been slow and tedious due to the dependence of local distribution utilities and lack of financing and awareness. However, the country has set a lofty target of achieving 40,000 MW of solar rooftop capacity by 2022 and has also announced large subsidies for the same.

When sunlight falls on silicon based solar panels, electricity is generated. However, since the electricity generation is DC (direct current), an inverter is required to convert the DC into AC (alternating current), on which most of our home appliances run. The extra power generated can be stored in batteries for use later (during the night, when the sun is not

around). This way our homes or commercial establishments can run on solar power either exclusively or partially.

Different solar products in India

Not only is solar energy competing with the mainstream sources of power like coal in India, different solar products are also gaining traction. Solar powered lights, water pumps, toys, inverters, ACs, cookers etc. are being increasingly used in the nation. Solar water pumps and lights are the two most popular solar products being prevalent in the rural parts of India, owing to the intermittent supply of power there. These solar powered products have not only made the lives of the villagers easier, but also improved their lifestyle as they do not have to depend on kerosene lights and diesel generators.

The Union Ministry of MNRE released a draft policy on micro and mini grids that will run on renewable energy sources like solar and wind energy. India is planning to set up 10,000 such projects, with average capacity of 50 kW each, to help the rural population in India.

Why do we need solar in India - comparing solar tariffs?

Solar power tariffs are gradually declining with each passing day, and has even started to reach grid parity in various places around the globe. In India too, some states are fast approaching this status. Solar tariffs have become competitive with the industrial and commercial tariffs across various states in India like Maharashtra, Uttar Pradesh, Andhra Pradesh, Tamil Nadu, Rajasthan, Gujarat etc. In Maharashtra, the industrial, commercial and domestic power tariffs are infact higher than the solar tariffs during 2015-16 itself.

The costs are declining and efficiencies are improving, leading to a large scale adoption of solar worldwide. Solar modules which are the integral part comprising a solar system today cost just ~39 cents/ watt in India.

Rooftop solar in IndiaWith India facing severe power problem

and rising electricity tariffs, saving in power bills is one of the major attractions in installing these rooftops. India has one of the highest irradiation levels in the world, when compared to other countries. Rooftop solar has tremendous potential in India because of its massive

advantages like low gestation period and reduced electricity bills. It also solves the problem of land scarcity and transmission issues in India.

Benefits of rooftop solar1. No delays in permitting, environment

clearance, and land citing – Large solar farms have to go through a myriad of regulations and clearances. There have been instances of lawsuits by wildlife and environmental groups against solar thermal and solar PV plants in California. This problem is non-existent in case of a rooftop installation. Free area of your home’s rooftop can be easily utilised for installing a rooftop.

2. Electricity transmission costs – Grid connection leads to additional costs for solar farms, while rooftop solar can use existing transmission infrastructure.

3. More grid stability – A large part of distributed solar is consumed locally, while farms supply 100% to the grid. That makes managing the grid difficult when solar penetration increases. A rooftop installation leads to a more balanced grid.A rooftop system can be self-owned or third

party owned, financed either through 100% equity or a combination of debt and equity. If it is self-owned, an individual can claim benefits

of metering (net or gross) policies, or can enter into solar PPA/ leasing with the third party. In India solar leasing is not popular, generally finance is through equity and debt.• Customer owned – This is the oldest

type of rooftop installation, wherein the customer is the owner and installs the system with his own equity or debt. The power generated is used for self-consumption and excess can be fed to the grid. The customer may use the entire power generated (captive/ off grid), feed all energy generated to the grid (gross feed) or use a part of power generated and supply the extra power to the grid (Net metering).

• 3rd Party owned – In this type of rooftop installation, third parties install these systems on the rooftops of its customers, either through solar leasing or

Power Purchase Agreement (PPA). The customer foregoes high capital investment for lease payments to these installers, who are the owners of this system installation.

• Integrated with utility – In the third type, utilities will install solar system on the rooftop of the customers and the power generated is fed to the grid.

Solar parks in IndiaIndia has some of the largest solar power

plants (known as solar farms) worldwide. Solar parks are becoming popular in India because they address the land acquisition problem, which is a major issue in the country. Other advantages include lower operational expenses, faster and easier clearances and shared development costs. The government plans to increase its target from solar parks from 20 GW to 40 GW, out of the 60 GW capacity allocated for grid connected solar power plants.1. Charanka Solar Park – is the first and

the largest solar park built in Gujarat, India under the leadership of the now PM of India. It has a planned capacity of 500 MW.

2. Rewa Solar Park in Madhya Pradesh India – The upcoming 750 MW solar park in Madhya Pradesh, India has been developed as a joint venture between SECI and MPUVNL. This will be the world’s largest solar park. This plant will be funded by a massive loan from World Bank. Once the project is completed by early 2017, it will be 3 times bigger than India’s solar park at Charanka, Gujarat. The power costs from this plant are set to establish new benchmarks for solar power in India, with tariff of Rs 5.5 /kWh only. The power will be sold to different states with MP getting 40% of the power.

iv. Waaree Solar – The company is one of the biggest manufacturers of solar panels in India with a manufacturing unit at Surat. The company has an experience with solar thermal and EPC utility grid projects.

Challenges facing the Indian solar industry

Despite a rising demand for solar, India does not have a robust manufacturing industry, with the country totally lacking in production of the key raw materials of polysilicon and solar wafers. The country remains completely dependent on imports for these crucial raw materials. The solar energy sector also faces issues in scaling, due to an absence of adequate transmission facilities. The poor

health of distribution utilities may also lead to challenges in growth of the sector in India as there might be payment issues. Land acquisition and lack of skilled manpower are also minor issues which may hurt the growth.

Though India has made grand plans like “Make in India” and “Ease of doing business” for encouraging foreign solar companies to set up business in India, the country still needs to provide land, utilities and clearances fast and at a cheap cost. India operates in an opaque manner with no one knowing what the subsidy is and how to get it. Countries like Malaysia on the other hand provide fast approvals and easy access to land and utilities, giving subsidies, which are streamlined and easily understandable.

After a thorough research into both sub types of vertical axis wind turbine rotors configurations, it has been decided to base turbine design on the Darrieus model. In this

project modified version of Darrieus type of wind turbine is designed...

Wind Power GenerationUsing Maglev Technology

AN EXPERIMENTAL STUDY ON MINIATURE FABRICATED MODEL


<< Experimental Study

Conventional wind mill having a maximum efficiency of 30% and energy efficient wind mill can operate in maximum

efficiency of 45%. The remaining energy is mainly lost in friction. If the Same wind mill is operating at 50% of its maximum speed the efficiency becomes very low and the frictional loss gets increased compared to power generated. The drawback of wind mill is that it cannot be operated at its full capacity all the time. Moreover, due to friction there will be wear and tear in machines. Due to the wear and tear the performance of the machine will deteriorate and also Normal windmill can start its generation from wind speed of 3 m/s.

With introduction of magnetic levitation to Vertical Axis Wind Turbine (VAWT), energy wasted in the form of friction can be saved and also windmill using magnetic levitation can start generation from wind speed at 1.5 m/s. Operation of windmill at lower speeds, increases the amount of energy harvested from the windmill. Power will then be generated with an axial flux generator, which incorporates the use of permanent magnets and a set of coils.

Introduction Renewable energy is generally electricity

supplied from sources, such as wind power, solar power, geothermal energy, hydropower and various forms of biomass.

These sources have been coined renewable due to their continuous replenishment and availability for use over and over again. The popularity of renewable energy has experienced a significant upsurge in recent times due to the exhaustion of conventional power generation methods and increasing realization of its adverse effects on the environment.

This popularity has been bolstered by cutting edge research and ground breaking technology that has been introduced so far to aid in the effective tapping of these natural resources, and it is estimated that renewable sources might contribute about 20% – 50% to energy consumption in the latter part of the 21st century.

Worldwide there is now over two hundred thousand wind turbines operating with a total name plate capacity of 432,000 MW as of end 2015. The European Union alone passed some 1,00,000 MW nameplate capacities in September 2012; while United States surpassed 75,000 MW in 2015 and china grid connected capacity passed 1,45,000 MW in 2015.

Unlike the traditional horizontal axis wind turbine, this design is levitated via Maglev (magnetic levitation) vertically on a rotor shaft. This Maglev technology, which will be looked at in great detail, serves as an efficient replacement for ball bearings used on the conventional wind turbine and is usually implemented with permanent magnets.

This levitation will be used between the rotating shaft of the turbine blades and the base of the whole wind turbine system. It does not need to vast spaces required by more conventional wind turbines.

Design of levitation system for the proposed miniature model of Maglev wind turbine

This section discusses detailed design of the Magnetic Levitation system for the proposed miniature model of Maglev wind turbine. Design of levitation system mainly depends on the selection of magnet and magnetic force required to levitate the wind mill. Design procedure is divided into two sections namely magnetic selection and magnetic force calculations.Selection of magnets

Some factors need to be assessed in choosing the permanent magnet selection that would be best to implement the Maglev portion of the design Nd-Fe-B Neodymium Permanent Magnet at room temperature exhibits highest properties of all of the magnetic materials.

It has a very attractive magnetic characteristic, which offers high flux density operation and the ability to resist

demagnetization. This attribute will be very important because the load that will be levitated will be heavy and rotating at high speeds – which will exhibit a large downward force on the axis. Based upon the above mentioned advantages, neodymium permanent magnet is used for levitation.

The permanent magnets that were chosen for this application were the N35 grade magnets. These are Nd-Fe-B ring shaped permanent magnets that are nickel plated to strengthen and protect the magnet itself. Magnetic force calculations

The force between the two selected magnets is calculated and this data will show whether or not this Maglev system will be able to support the load of the wind turbine. Calculating the force between two magnets forms an important role as it decides the weight of the turbine.

The main obstacle in this permanent magnet design was finding the distribution of the magnetic flux in this magnetic “circuit”. Variables that needed to be considered were the distribution in the air gap and the distortion caused by the opposing magnetic force.

To understand how to calculate the repelling force between two magnets, one must first understand how to relate the force, F that is caused by the magnet to its flux, ф.

The relationship between the force in the air gap of a magnetic circuit and flux is clear. What was proven can now be applied to the permanent magnet concept which applies to this application.

Based upon the magnetic force required to levitate the wind turbine, the turbine section is designed. Greater thickness magnet should be used to levitate wind mill in order to harness more power. Turbine / Rotor design mainly depends upon the magnets used for levitation.

Design of Turbine and Axial Flux Generator for the proposed model of Maglev wind turbine

This section provides brief design of turbine/Rotor and axial flux generator design for the Maglev Wind Turbine.Turbine design

After a thorough research into both sub types of vertical axis wind turbine rotors configurations, it has been decided to base turbine design on the Darrieus model.

In this project modified version of Darrieus type of wind turbine is designed and the final fabricated rotor blades design is pictured in Figure 3.1 Design parameters like Tip speed ratio, material selection, and solidity and power coefficient are considered while fabricating rotor blades.

Number of blades used in this prototype is 6 to avoid turbulence. Each separated from one another by 45°, once the wind blows one blade should come after each rotation. Each blade having a curvature of 180° to harness wind from all direction.Design of axial flux generator

The axial flux generator designed in this project utilizes the changing magnetic field produced by the magnets to induce a voltage. Axial flux generator consists of rotor containing permanent magnets and stator containing coils.Rotor design

Rotor contains eight neodymium permanent magnets of dimension 25mmx5mm – and one circular ring shaped neodymium permanent magnet of dimension 40mmx22mmx7mm used for levitation purpose also act as a magnet bearing at the bottom of the circular disc.

Similar disc type magnets of 25mm x 5mm diameter are arranged as alternate poles one after the other, along the periphery of the rotor made of plywood of 40mm diameter as in figure. Magnets are selected on the basis of

B-H curve, which depicts operating point of permanent magnets. Each magnet separated from each other by 15mm distance. These magnets are responsible for the useful flux that is going to be utilized by the power generation system.Coil design

The number of windings per coil produces a design challenge. The more windings will increase the voltage produced by each coil but in turn it will also increase the size of each coil. In order to reduce the size of each coil, a wire with a greater size gage can be utilized.

Again another challenge is presented; the smaller the wire becomes the less current will flow before the wire begins to heat up due to the increased resistance of a small wire.

Each one of our coils has a measured resistance of 60Ω; a smaller gage wire would further reduce this resistance.

Series of experimentation has been with coil of turns 100 and 200 and found the very less voltage of 0.2 volts and 0.6 volts respectively. So, coil of 800 turns is selected finally for the design of stator coils for the proposed model of axial flux generator.

Four windings are used in this project each having 800 turns 30 SWG which are placed as a sandwich between two permanent magnets.

Air gap of 3 cms is maintained to have proper flux leakage through the coil.Coil arrangement

When designing a generator, the application which it will be used for, must be kept in mind. The question must be answered, which property, the current or the voltage, is of greater importance? The problem that is produced by a larger coil is the field density is decreased over the thickness of the coil. The thickness of the coil is what reduces the flux magnitude. In our design, we have chosen to sandwich the coils between two attracting magnets.

This design will increase the field density greatly improving the voltage output. The increased thickness of a coil would therefore increase the distance between the two magnets reducing the flux. A balance must be found between the amount of voltage required and the amount of current required. We have chosen to use a very high gage wire to increase the amount of voltage the generator can provide. If the generator is required to produce more current the coils can be replaced with those of a smaller gage wire. The permanent magnets we have chosen to use provide a very strong magnetic field.

In this project coils are connected in series keeping amount of voltage required. The number of turns adds to produce a greater voltage. This design choice will increase the voltage each coil will produce.

The voltage produced by each coil can be calculated using Faraday's law of induction:

Results and conclusionsConcept of magnetic levitation is

successfully illustrated in this project and the design of axial flux generator and levitation system is fully incorporated in the fabricated model as shown in the figure in page 36.

Rotor blades are designed using concept of aerodynamics and parameters like tip speed ratio, power coefficient, solidity, material used, design of blades, all are incorporated while designing and fabricating a wind turbine using magnetic levitation wind turbine.

Design details of axial flux generator and levitation system implies voltage induced in a coil depends upon the permanent magnets, which creates magnetic lines of force based upon their magnetic strength.

In order to levitate a wind mill, selection of magnet plays a very important role. Magnetic forces require to levitate wind mill depends upon the turbine/rotor design.

At the end of the project, the magnetically levitated vertical axis wind turbine was a success.

This project demonstrates the utilization of the renewable resource (wind energy) in an efficient way. This type of generation can be used in remote places, where conventional power supply is uneconomic.

The wind turbine rotors and stator levitated properly using permanent magnets which allowed for a smooth rotation with negligible friction.

At moderate wind speeds the power output of the generator satisfied the specifications needed to supply the LED load. An output ranging from 5V to 60V was obtained from the magnetic levitated vertical axis wind turbine prototype.

Future scopeVoltage generated from Maglev wind

turbine can be increased by increasing the number of turns of the coil in proportion with

magnetic lines of force obtained from the permanent magnet.

Therefore, greater thickness of the permanent magnets should be used while fabricating the axial flux generator.

The Maglev windmill can be designed for using in a moderate scale power generation ranging from 400 Watts to 1 kW.

Also. it is suitable for integrating with the hybrid power generation units consisting of solar and other natural resources.

igus Receives Top Cleanroom Classification For Modular Corrugated Tubes

With the e-skin, igus has developed a modular corrugated tube, which is not only extremely easy to open, but unlike comparable energy supply products, also provides an unsupported operation in the smallest installation spaces. Now, the motion plastics specialist has won the

strict IPA ISO Class 1 certification for the product. This gives customers maximum safety for applications in cleanroom environments...

Absolute air purity is essential in many industries, especially in production, in the medical and pharmaceutical technology, semiconductor industry, aerospace technology, nano technology

and measurement technology. Any contamination in cleanroom conditions has a direct damaging impact on products and processes and costs a lot of money. The e-skin from igus is used in the area of energy supply and provides a safe, robust and flexible supply of systems with data, media and energy without generating airborne particles above the narrow limit, which can contaminate the room.

Enclosed structures and abrasion resistance for clean production

Design and material of the e-skin have enabled the acquisition of the IPA ISO Class 1 certification through the Fraunhofer Institute. The corrugated tube is made up of tribologically optimised, abrasion-resistant plastic and its separable upper and lower shells can be easily

put together by a ‘zipper’ to a fully enclosed tube, which is highly dust-proof and water-resistant.

This simultaneously guarantees its cleanroom suitability as well as a quick filling and maintenance of the cables. The assembly-friendly e-skin is also extremely light and ideal for small installation spaces, for instance in pick & place applications. Due to the stiffness of the material, the rib profile and a defined direction of motion, it is even applicable for short unsupported distances, unlike other corrugated hoses. Interior separation is also available as an option.

Upper and lower parts of the ultra-light e-skin join together immediately to make a

sealed, cleanroom-compatible and unsupported energy supply system…

Reactive PowerCost Analysis


<< Generator

39

The Independent System Operator (ISO) procures reactive power as an ancillary service from the synchronous generators and condensers to maintain security of the power system. Since cost is

involved to procure reactive reserve services and to maintain the services, the service providers should be remunerated according to their reactive power supply to the system. For the recovery of the cost of reactive power, most of the utilities charge industrial consumers based on KVA demand and penalize the utilities for the poor power factor. This fixed cost recovery of reactive power is insufficient and in the competitive markets may not provide accurate price signal for the ancillary providers. Looking into the limitations of a reactive power price to be charged from the consumers based on power factor penalties, authors suggested the use of economic principles based on marginal theory.

However, the prices of reactive power based on the marginal price theory represent a small portion of the actual reactive power price. Reactive power has typical characteristics due to reactive power generation equipment and local characteristics of reactive power of loads and transmission system behavior; therefore, it is difficult to access its cost characteristics. For the assessment of reactive power cost, many authors proposed different techniques. A real time pricing method for reactive power using OPF method was proposd in.

The reactive power marginal price is typically less than 1% of the active power marginal price and depends strongly on the network constraints as proposed in. Gill et al. proposed a conceptual framework for remuneration and charging of reactive power cost. A cost based reactive power dispatch method is proposed for reactive power cost calculation and explicit and implicit cost of reactive support from generator and transmission system is also analyzed.

However the method of opportunity cost calculation of reactive support from generators is quite complex. A summary of different methods for reactive power pricing has been discussed using different objective functions for calculation of marginal prices of reactive power using optimal power flow based approach in.

A similar approach of generator cost model of reactive power support as discussed in is based on the opportunity cost of generator reactive power dispatch and is presented in. Capital cost remuneration of reactive compensators has also been incorporated in an objective function in.

Several methods for incorporating reactive power dispatch into nodal pricing and dispatch algorithms were proposed in. A method of cost-based reactive power pricing minimizing the cost of reactive power production of generators and capacitors are proposed in.

Ro has presented the reactive charging scheme composed of recovering capital cost and operational cost. The proper recovery of reactive power cost with help sustaining the ancillary service providers in the electricity markets. The cost must be decided based on the capability limits of the generators at each operating point due to the load and power factor variations. In this article, reactive power cost characteristics have been obtained developing the reactive power capability charts at different operating points and utilizing them to find lost opportunity cost.

The article presents: (i) Cost characteristics determination for synchronous generator based on capability charts, (ii) cost analysis of reactive power supported by synchronous condenser. The reactive power cost function has been obtained for reactive support of generator. These cost functions can be utilized for remuneration of reactive power supplied by the synchronous generators and condensers bidding in the ancillary service markets.

Reactive Power Capability of Synchronous Generators

Synchronous generators are the major sources of reactive power generation. The generators supply reactive power meeting the base load requirements and can be operated as synchronous condenser supplying reactive power to the system without any active power fed to the system. The reactive power supply of the generators are limited due to the armature current, field current limits, and end region heating limits. These limits need to be considered during the analysis of reactive power support and the cost of reactive power calculations.Armature current limit

Armature current is responsible for heat loss in the windings as I2R losses and increases the temperature of the conductor. Therefore, the one of the limitations on generator rating is the maximum current that can be carried by the armature without exceeding the heating limitations. The real and reactive power supplied by the generator can be computed using the following expressions for complex power with the terminal voltage Et and armature current, It.

S=P+jQ = Ê.Î (1)P=|Et||It|cosφ (2)Q=|Et||It|sinφ (3)The equations plotted on P-Q diagram are in the form of circle with

centre on origin. Field current limits

The field current is limited due to the heating of the windings. With terminal voltage Et and rated armature current Ia each equal to 1pu, the locus of the excitation current can be shown as a circle with centre on the Q axis as shown in Fig. 1. The figure also shows how the active power and reactive power capability curve is varying with the armature current and the field current. The reactive power generation for a cylindrical and salient pole generator is different and the real and reactive power generated, and the maximum reactive power can be computed for cylindrical pole and salient pole generator as follows:a) For cylindrical pole rotor generator [1], the q-axis voltage, real, and

reactive power is given by:(4)

Where,Ifd = field current, P = active power pu, δ =load angleQ = reactive power pu, Et=terminal voltage pu, Xs = synchronous reactance puEq = no load generator voltage p.u., Xad = effective reactance (0.2 to 0.4 Xs) Xq = reactance pu in q-axis, Xd = reactance pu in d-axisFor cylindrical rotor syn. Generator, the synchronous reactance Xs = Xd and nominal power factor is 0.9End region heat ing limits

A third limit on the machine due to the localized heating in the end region of the armature imposes a limit on the operation of synchronous machine. The end turn leakage flux enters and leaves in the direction axial to the stator lamination. This cause’s eddy current to flow in the lamination and result in localized heating in the end region. In the over-excited condition, it keeps the retaining ring saturated, so that leakage flux is small. However, in the under excited region the field current is low and the retaining ring is not saturated, this causes increase in armature end leakage flux. The real and reactive power taking the end regions heating limits into account, the real and reactive power are obtained as follows:

The end region heating limit is shown in green color in Fig. 1. Synchronous condenser mode

A synchronous condenser is a synchronous machine running without a prime mover or mechanical load. In this situation, the machine only draws the real power to meet losses only. Practically, most of the machines are designed for one specific duty only, hence there are a finite limitations to the area within which any given machine may be operated successfully with about 20% to 30 % overload up to 30 minutes. When a machine is operated in the condenser mode, either in overexcited or under excited region by varying excitation current, it controls reactive power. Figure 2 shows that the condenser mode region is much smaller

than the generator mode region. Region (i) and (iii) supply reactive power to the system in generator and condenser mode respectively. Region (ii) and (iv) absorb reactive power from the system in generator and condenser mode respectively. Negative P indicates that active power is absorbed from the grid to keep machine running in condenser mode and for supplying the losses.

Cost model of synchronous generator reactive power supply

To provide the more reactive power, a generator may reduce the active power and may forego the cost of active power. This cost of forgo active power is known as the lost opportunity cost of generator. Since generator output is limited by its MVA rating, the accurate model of such opportunity cost should be derived from the generator capability curve at each operating point.

If a generator produces reactive power over and above its base case values, then its cost for generating reactive power should be equal to reduced active power (P) cost. The reactive power above the rated reactive power generation curve is limited by the field heating limit equation and below a rated reactive power generation, the curve is limited by armature limit equation. The lost opportunity cost can be determined above the rated reactive power requirements and below the maximum limit reactive power generation from the generators. Therefore, the reduction in active power has to be calculated by the field limit equation. From field current limit (4) and (5):

The real power output limited by the field limits can thus be obtained as:

Qrated =S*sin(Φ) (17)The change in the real power can be obtained from its rated value to any operating value as:

∇P1 = Prated - P1 (18)The cost of decrease in the real power output can be obtained using the fuel cost function.Cost (∇P1) = a(∇P1)2 + b(∇P1) + C (19)This cost of reduced active power shall be recovered from the reactive power support obtained from the generators as:

The cost of reactive power following the capability chart of the generators can thus be plotted based on the reactive power support provided by the generators. Based on the data obtained, plot the graph Q vs Cost (Q) and by using of curve fitting toolbox in MATLAB, quadratic equation can be obtained for the reactive power cost as:

Cost characteristics curves for generators reactive support

The cost of real power and reactive power has been obtained for 500MVA and 60 MVA generators. Based on the capability chart of the 500 MVA generator, the real and the reactive power outputs have been obtained and the respective cost have been obtained at each operating point within the maximum reactive power limits of the generators. The cost of the active and the reactive power for the generators are obtained and are shown in Figs. 3 to Figs. 8. As observed from the figures, the lost opportunity cost can be recovered at every operating point on the capability curve of the generator. At maximum reactive power supply point, the real power given by the generator is zero.

The reactive power cost curve obtained for 500 MVA generators is shown in Fig. 4. Up to rated active power generation; the cost of reactive power is zero. Above the rated reactive power requirement, there is decrease in the real power generation and increase in the reactive power generation, thus the lost opportunity cost has to be recovered from the reactive power cost as an ancillary service. The cost of active power at rated values and at any other operating point on the capability curves of

60 MVA generators are also shown in Fig. 5 and 6. The reactive power cost curves obtained for 60 MVA generators are shown in Figs. 7 and 8. The cost of reactive power at rated active power generation is zero and increases with reduction of active power above the base case. Based on the results for both the 500MVA and 60 MVA generators, the cost characteristics for reactive power support have been obtained and the cost coefficients obtained for reactive power cost corves are given in Table 1.

ConclusionsIn this article, reactive power cost functions have been obtained for

the synchronous generators for their reactive support. The cost function for synchronous generators has been obtained based on their capability chart. The reactive support have been obtained for different sizes generators and using curve fit technique, quadratic cost functions have been obtained for synchronous generators. The cost of reactive power has also been obtained with generator in condenser mode. These cost

functions can be utilized in the ancillary service markets to remunerate the generators for their reactive power support.

How is the demand for Energy Management Systems (EMSs) increasing in India?The rising cost of energy is causing organizations to evaluate smart ways of saving energy. Energy suppliers are increasingly penalizing organizations that use inefficient assets or devices with a low power factor. Simultaneously, governments are raising the bar for compliance with energy standards and reduction in carbon footprints. While growing demand is part of the problem, poor infrastructure equally contributes to electricity shortfalls that have hindered recovery in India’s industrial sector and hurt its overall economic growth. Demand is far outpacing supply in meeting the rapidly growing electricity needs of the country. Electricity shortages have resulted in the loss of profits for many companies, loss in productivity as plants and businesses

DEIF has introduced the Automatic Sustainable Controller (ASC), a solution that provides integrated solution for systems with utility, diesel and solar power source. The

system provides an interface between the diesel/gas genset and solar, with or without the presence of utility power – a solution that enables you to share the load between solar PV cell and diesel/gas genset with maximum solar penetration, thus resulting in maximised savings even during utility failure.

DEIF’s solar solution is available for both – as Power Management for systems with multiple sustainable power sources, or as an add-on solution for retrofits or existing plants.

The ASC supports interface with solar PV inverter from a number of leading manufacturers namely ABB, SMA, Schneider Electric, Gamesa Electric, Fronius, Sungrow, Delta, Huawei and many more...

Their collaboration with ABB has resulted in a “Declaration of Compatibility” certificate, which states that the ASC is capable of controlling and reading data from the ABB TRIO inverter series and that it can be applied without compromising inverter warranty. Similarly, other inverter manufacturers are in the process of issuing compatibility certificates for the ASC.

Schneider Electric launched their Conext CL inverter series for the solar market, which includes an interface with the DEIF ASC controller. This solution works with the grid and a diesel genset to form a complete grid management solution.

Conext CL inverters are designed to respond rapidly to power curtailment commands from controllers enabling integration of PV power in hybrid grids.

The ASC from DEIF controls PV power from the Conext CL inverters to integrate seamlessly with diesel genset powered loads. The company offers a customization option to add an Automatic Genset Controller AGC -4, to provide a complete plant management solution.

Fronius International GmbH, another inverter manufacturer’s solar solution with DEIF’s ASC is presented in their product catalogues.

DEIF is working progressively with many solar inverter companies to help the end customers enjoy a seamless integration of power. The future of the interface between Controller and Solar inverters will be Sun Spec – and DEIF has already prepared its ASC to this protocol of the future.

Many, if not most storage batteries receive the bare minimum of attention until one day they are called into service and are expected to provide a dependable source of power for a pre-

planned period. But how can users be sure that their batteries will be equal to the demands placed upon them? The answer is that only regular testing can provide this level of assurance.

The next question is the type of testing to use. Let’s start by making it clear that the only way to reveal the full information about the condition of a battery is by load testing. Essentially, this involves discharging the battery into a dummy load and recording its performance.

It is usually recommended that the condition of important battery installations is thoroughly evaluated by performing a discharge test at least once a year. Specially designed test sets, such as those in the Programma Torkel range from Megger, are available to make this process as easy and convenient as possible.

For complete discharge testing, the battery must be taken out of service for the duration of the test. This can easily be as long as two days to allow a full discharge/charge cycle to be completed. Clearly this test method, while offering the most accurate results possible, is costly, time

consuming and often inconvenient. How many users, for example, are happy to be without standby power for two full days, or to go the cost and inconvenience of having an alternative battery available to provide cover while the testing is carried out?

One way of addressing this problem is to carry out limited discharge testing. With Torkel test sets, for example, testing can be carried out by discharging the batteries by up to 80% without taking them out of service.

This is a useful solution, but it is not perfect. The test is still time consuming and, although the batteries remain in service, should they be called upon to supply power at the point of deepest discharge during the test, they will only have 20% of their full capacity available.

For these reasons, many alternative methods of attempting to assess battery conditions have been proposed.

One of the simplest, or so it seems, is to measure the battery’s float voltage – the voltage at its terminals when it’s on charge. This is undeniably an important parameter, and if it is abnormal it indicates that further investigation is needed. If, however, the float voltage is normal, this gives no indication whatsoever about the condition of the battery.

Another approach is to measure the specific gravity of the electrolyte, particularly in lead acid batteries where sulphate is part of the electrochemical reaction. When the battery is discharged, some of the sulphate migrates to the plates and the specific gravity of the electrolyte falls. Conversely, when the battery is fully charged, all of the sulphate is in the electrolyte and the specific gravity rises.

Measuring specific gravity therefore gives an indication of the battery’s state of charge, but it has never been possible to show that there is a link between specific gravity and battery capacity.

In fact, the only approach which has been demonstrated as providing information about battery capacity reliably and without taking the battery out of service is impedance testing. The impedance of a cell is, in fact, a measure of its ability to deliver current and it has been shown that impedance correlates with battery capacity.

The correlation is not 100% – as stated earlier the only 100% certain way of determining battery performance is by load testing. Nevertheless, impedance testing is an excellent way of locating weak batteries in a bank.

This method of testing is used in Megger’s BITE 3 range of battery test sets. It works by applying an AC voltage to the battery and measuring

know your battery

Secondary batteries play an essential role, usually as a source of standby power, in many areas of business and commerce. To be sure that those batteries deliver their full performance when called upon to do so, regular testing is essential. A systematic approach to this testing will give the best

results, as Damon Mount of Megger explains...

the resulting current flow. Since the applied voltage is known, the impedance of the battery can be calculated using Ohm’s law. Extensive research has confirmed that this impedance is, to a good approximation, inversely proportional to the capacity of the battery.

The benefits of impedance testing are easy to see. It is completely non-invasive, and it is fast. It takes only around 30 minutes, for example, to test a typical substation battery bank. In addition, the charge held by the battery is not affected at any stage of the test and, as already mentioned, there is no need to take the battery off line.

All of this having been said, it’s still important to remember that impedance testing is an indirect measure of battery capacity. While valuable, it can, therefore, never offer the same degree of accuracy and certainty as a full load cycle test.

What then, is the best way of monitoring the condition of important battery banks? Megger suggests using both load cycling and impedance testing.

Full load cycle testing carried out once per year will yield accurate information and provide an excellent baseline for impedance testing. Impedance testing carried out on a much more regular basis will provide reassurance throughout the year that the condition of the battery has not deteriorated significantly.

Of course, loss of capacity is not the only ill that can befall a battery bank. It has been stated, for example, that loose inter-cell connectors cause around 50% of the failures in battery banks.

The connectors loosen because of the heating and cooling that takes place during charging and discharging – the cell terminal posts expand and contract and, because the lead from which they are made is very malleable, they cold flow with every cycle. Fortunately, problems of this kind can be detected relatively easily by testing with a low-resistance ohmmeter, such as Megger’s DLRO.

Another common problem is earth faults, which are often caused by water ingress on large distributed systems. In large batteries, these faults can be notoriously difficult to find using conventional methods based on resistance measurements.

A better solution, and one that can be used whether the battery is on-line or off-line, is to inject an AC signal into the battery system. The amplitude of the resulting signal in the battery feeder cables can then be easily measured with a clamp-type probe. Since the signal amplitude is inversely proportional to the fault impedance on the feeder, the location of the fault can readily determined.

The Megger BGFT battery ground fault test set uses this approach, and provides a fast convenient and reliable method of detecting and locating faults of up to 100 kohms.

Other factors relating to battery operation deserving of careful attention include float current, ripple voltage and operating temperature. Float current is the current delivered by the charger when the battery is in its fully charged state. Normally this current is small, but if it starts to increase for any reason, the temperature of the battery will rise.

The increase in temperature allows more current to flow, which further increases the battery temperature, allowing even more current to flow. The result is thermal runaway and, in extreme cases, this has been known to lead to battery meltdown, particularly in VRLA batteries, which have no free electrolyte that can evaporate to help keep the batteries cool.Fortunately, the onset of thermal runaway is usually relatively slow – of the order of months – so regular monitoring of float current can prevent problems of this kind.

A high ripple current is often indicative of a fault in the battery’s charging circuitry – possibly the failure of a diode in a bridge rectifier.

Excess ripple current again increases the heating of the battery, thereby shortening its life. Regular checking is recommended and the better battery testers, such as Megger’s BITE products, incorporate facilities for this.

Finally, regular measurement of the battery’s operating temperature is invaluable, since high temperatures invariably lead to premature failure. As a rule of thumb, battery life is halved for every 10ºC increase in temperature. This means that a battery with a rated life of 20 years, which is operated at 30ºC rather than 20ºC, will only have a life of 10 years.

Throughout this article, particular emphasis has been given to the desirability of regular testing. The reason is simple. One test in isolation may well provide useful information, but a series of tests carried out over a period of time will not only provide much more information, but will also make the information vastly easier to interpret.

A sudden change in a test result that has previously remained almost constant, for example, immediately suggests that further investigation is desirable, even if both the old and new values in isolation would be

considered as falling within the acceptable range. Specialised software is available from suppliers like Megger, which

makes the storage, trending and analysis of battery test data straightforward tasks.

At first sight, monitoring the condition of storage batteries may appear to be a complicated undertaking.

As this article has shown, however, if the testing regime is properly planned and split into simple tasks that can readily be carried out with modern instruments, the overall effort and inconvenience is small.

This is particularly true when a comparison is made with the inconvenience and costs – direct and consequential – of a battery failure. Megger’s advice on batteries is, therefore, straightforward – keep an eye on your batteries with regular testing...

As their temperatures rise solar panels become less efficient, producing less electricity. Some defects can cause them to break down or even produce a reverse current, which might damage the

entire solar plant. Thermal imaging cameras can be used to detect hot spots in the panels from a distance, which makes it a lot easier to find defects before they become devastating breakdowns.

The Italian solar panel installation company ELEM srl is one of the companies that is working together with Thermographic S.A.S. di Ermoni Alberto e C., an experienced thermographic inspection agency to offer thermal imaging inspections to their clients. This Melzo, Italy, based thermography agency offers thermographers with several decades of experience with thermography. One of these inspectors is Alberto Ermoni, a Level II certified thermographer.

“Thermal imaging cameras from FLIR Systems are the ideal tools for the inspection of solar panels,” says Ermoni. “This inspection method is non-destructive and non-invasive. You can use thermal imaging to inspect the solar panels under load, so no shutdown is required. When used properly, thermal imaging cameras will show accurate temperature differences between cells or within a single cell that allow you to identify faults in an early stage.”

Inspect the entire systemThese inspections are also not limited to the solar panels alone. “You

can use thermal imaging to inspect the entire system, from the solar panels themselves to connections, inverters, fuses and all other electrical components in the system”, explains Ermoni. “If any part of the systems starts to wear down or develops a higher resistance for some other reason, the corresponding increase in temperature can be detected very easily with a thermal imaging camera, so you can fix the problem before the system fails.”

The thermal imaging camera Ermoni uses for these inspections is the FLIR T640bx. “This camera combines top notch image quality with advanced features like wireless WiFi connectivity with a Tablet PC and a wireless Bluetooth connection to selected Extech test & measurement

tools with the MeterLink feature, such as the Extech EX845 clamp meter. These wireless connections really make a huge difference. Another feature that I use often is the Picture-in-Picture feature. This overlay of a thermal image over the visual image allows me to better localize the hot spots.”

Wireless connection with Tablet PC or smartphone

The FLIR T640bx thermal imaging camera contains a microbolometer detector that produces thermal images with a resolution of 640x480 pixels and at a thermal sensitivity of 35 mK (0.035°C). The ergonomic design allows the thermographer to look at objects from all possible angles. With its bright LCD screen and viewfinder it operates well, even in the sunny conditions that are ideal for solar panel inspections.

The wireless WiFi connection between the FLIR T640bx thermal imaging camera and a Tablet PC or smartphone that is running the FLIR Viewer App makes it easy to show inspection results to clients on site and allows the inspector to produce reports on location, reducing the amount of time spent behind a desk.

The sales of solar panels are soaring, which help in reducing CO2 emissions at electricity plants. Over a time solar panels may develop defects that can be easily fixed if detected on time, but can cause a severe drop in energy production and in some cases even start a fire if left unchecked. That is why more and more solar panel installers cooperate with experienced thermographers – that offer regular thermal imaging inspections to ensure the safety and effective deployment of solar systems...

The MeterLink connection over Bluetooth allows the FLIR thermal imaging camera to automatically embed measurements from selected Extech measurement devices with the MeterLink feature, making writing down the measurements on a piece of paper redundant. This not only speeds up inspections, it also reduces the risk of human errors.

Interchangeable lensesOne other very important factor in Ermoni’s choice for the FLIR

T640bx thermal imaging camera is the fact that it has interchangeable

lenses. “In some cases you are standing on a raised platform inspecting solar panels from a distance of 10 meters, but in another situation you might be inspecting the back end of panels from less than one meter distance. In these different situations you need different optics, a telephoto lens for the inspection from a distance and a wide angle lens for the short distance inspections. Many other thermal imaging camera models do not feature this flexibility in optics.”

Good solar panel inspections require more than just a good thermal imaging panel alone, however, Ermoni stresses. “Performing solar panel inspections properly can be quite a challenge. When you inspect the front of the panels you need to know how to choose the right vantage point and viewing angle to prevent reflections, but you also need to know about emissivity and reflected temperature, if you want to get accurate temperature readings."

ITC certifiedFor that reason Ermoni has followed several courses at the FLIR

Infrared Training Center (ITC). “You really need this type of training to be able to deliver accurate reports,” says Ermoni. After becoming a Level II certified thermographer, Ermoni even became ITC instructor himself. “Having seen the importance of proper training in the field I am eager to share the knowledge I have gained with other thermographers.”

To Ermoni, the choice for a FLIR thermal imaging camera was an obvious one. “FLIR offers the whole package: very high quality cameras with advanced features and excellent image quality, good software, very good after sales service and training courses to match.”

Automatic Particle Counters are used for an array of

specific specialized applications, including quality control of liquid filled power transformers. Due to the high amount of transferred voltage, transformers are rapidly heated up, and thus need to be adequately cooled. Power transformers are usually cooled with oil (e.g., mineral oil or silicone transformer liquid). The insulating oil does not only serve as coolant, but it also insulates empty spaces between conductive materials. Particles in the oil adversely affect the dielectric strength of the insulating oil. Depending on type, size and quantity of particles (metallic, water etc.), a flash-over could be generated, which can be hazardous. The oil itself turns into an electrical conductor and hence loses its insulating function.

Before a transformer is put into operation, the insulating oil needs to be monitored with a particle counter. In the case of an alarmingly high particle concentration, the oil must be treated or replaced in order to decrease the possibility of a flash-over. Water droplets in the oil (for instance) can be eliminated through prior drying. Solid particles are removed through filtration. While the oil is being processed or while the transformer is being filled with oil for the first time, the particle counter monitors the oil cleanliness. As soon as pre-defined oil cleanliness is achieved, the flushing process is stopped automatically. The oil cycle of a filled transformer is hermetically sealed, so contaminants from the external environment are unable to enter the system. Due to case vibrations and mechanical switches, however, the particle number in the insulating oil rises during operation. It is therefore imperative to monitor the insulating oil regularly during operation. If too many particles are

counted, filtration or exchange of the insulating oil will ensure trouble-free and safe operation.

The analysing methods for particle counting of insulating liquids are standardised in the IEC 60970 and the ASTM D6786. Both standards require the calibration of Automatic Particle Counters according to ISO 11171.

Founded in 1992, PAMAS develops, liquid particle counters to measure particulate contamination in liquids. The highly sophisticated optical sensors are manufactured at the company’s plant in Germany. Due to its own R&D, PAMAS is the market leader for high-quality liquid particle counting systems. Manufacturers and operators of transformer systems acknowledge and appreciate PAMAS (www.pamas.de) particle counters due to their reliability, their measuring accuracy and their multiple application profiles.

In India, Pamas has a full-fledged application and service lab in Bangalore, and the company operates through a network of distributors throughout the country. For further information – E-mail: [email protected]

The demand of power is continuously increasing. Therefore, regenerative energy mix has become an increasingly

important energy source from ecological as well as economical point of view. In addition to thermal power, photovoltaic is also fast gaining importance. Solar Power is the most efficient and clean solution for alternate power sources. Innovation for green ecological power generation is becoming important in power technology. Maximum availability of all system components is the basic perquisite for economical and safe operation.

According to the statistics of the insurers, the most frequent cause of damage to electrical items and of their failure are surge voltages caused by lightning strikes and switching operations. Lightning surges in the PV system can damage PV modules and inverters. This can have serious consequences for the operation of the system as it can lead to break down of the plant. Firstly, high repair costs, for example, those of the inverter have a negative effect, and secondly, the system failure can result in considerable revenue loss for the operator of the plant.

Increased availability of photovoltaic system

Photovoltaic plants are generally installed in exposed locations, it is important to consider that the exposed location of PV systems presents an acute threat of damage due to lightning currents and surge voltage. The threat of damage from surge voltage is ongoing and just one incident can cause the huge financial loss and erosion of considerable profit margin. Surge protection for photovoltaic systems is preventive, avoids unnecessary annoyance and helps plants run incessantly on track. Hence, there is a need for protection device for photovoltaic system in order to avoid any damage and shutdown resulting in huge loss.

Phoenix Contact surge protection – Lightning protection concepts for PV systemsProtection circuit devices

Surge protection devices must be considered for all circuits: On the DC side between L+, L- and the earth potential, and on the AC side

between the phases L1, L2, L3, the neutral wire and the earth potential. In addition, all other circuits (e.g., data and measuring technology circuits), which are connected to the inverter, must be protected with specially designed surge protection devices for solar application.Direct and indirect lightning protection

Direct (exterior) lightning protection must be implemented by observing the protection zones and galvanic separations by means of lightning rods for the PV generator. For induced effect of lightning impulses, there is a need to provide surge protection device on the power supply side (Both AC & DC).

These must be tested against both lightning and switching means T1 T2 SPD need to be installed at inverter box, and string combiner box in case installation has more than 4 PV panels. Phoenix Contact offers surge protection for voltages from 24 VDC – 1500VDC applications.

What kind of post-sales support do you give? How do you manage that?It is a known fact that customers buy products from us for the value proposition offered once – but they continue to come back to us again and again depending on how we as suppliers engage with them in the post sales scenario. Starting with our founder, we all at Rishabh follow the strong philosophy of ‘Customer First’. Customer satisfaction is the prime focus of each and every team member at Rishabh – and till date we have adhered to this principle very dedicatedly and will do so going forward too. We have always made special efforts to keep our customers engaged. In addition to periodic updates through e-mailer, we have also given our customers an option to reach out to us at a nodal point electronically with their views and issues. Further, we have started with Customer Engagement Programs in the form of half day meets in select cities/towns. We also often conduct in-house seminars at customer’s facility where our team provides product training focused on helping customers team understand how they can use our products more efficiently in their respective processes or applications. In addition, we have a strong team of after sales service at HO, and also in the regional offices who can provide post sales support, should any need arise, in real time. Rishabh has designed a website training program, which serves as an online training module covering our entire product range – this is another mechanism available for self learning about Rishabh offerings and get trained on usage. We believe in customer feedback being crucial to understand their expectations and how we stand up to it. Finally, this helps us in serving them better. For this purpose starting with self, all functional leaders and select team members across R&D, Engineering, Production, and Marketing etc., travel to meet customers from time to time.

or business verticals like IT, services, logistics, hospitality etc. over the medium to long term. It would be difficult to cover all aspects of this emerging scenario wherein control and test & measuring instruments would find usage, hence focusing on one of these viz. power sector. We clearly see sufficient availability of power for all users across India over the next few years becoming a reality. With both base load and peak load deficits expected to see a down trend in most tier I and tier II locations in the country, the new emerging domain, in the power sector, would be quality of power. In time to come, attention of entire power instruments users will be drawn to better power quality. The ultimate performance of equipment or machine in question would depend on the quality of power it is receiving. In light of this, manufacturers of such equipment will have to design and produce equipment with suitable configurations wrt power utilization but test & measuring instrument OEMs will also have to develop products that help analyze quality of the power – and subsequently also improve the same. At Rishabh, we have a clear road map to address this need of the industry and we are coming up with high-end devices like panel mounted Power Quality Analyzer, hand held (Portable) Power Quality Analyzer, Power Factor Controllers etc. The only message we would like to give for all power instruments users is to remain aware, bring more focus on assured power quality as this will have a direct impact – not only on the equipment but also on their overall business economics. Another important factor which needs to be highlighted is safety. Lack of proper safety provisions in power instruments which one is using is like riding a bike in a race without a helmet. It is critical that customers choose products prudently. Checking for safety features available with the product is very critical since finally there is human life and well being linked to that instrument being used in field conditions. Decisions taken only with one dimension of lower prices but may be by compromising on the quality or safety features can prove to have substantial fall outs. We encourage our customers to study the standards the product being procured is complaint to in addition to price and external appearance of the product since finally performance matters. Hence, I would like to recommend potential buyers to remain insistent on safety, latest standards, guaranteed product performance and proven track record of the manufacturer.

The group is planning to expand the production of large diameter bearings, which can be used as key components for blade and jaw adjustment in wind turbines...

On the Guaratinguetá site, the Liebherr Group runs two production companies: Liebherr Brasil Ltda., founded in 1974, manufactures excavators, wheel loaders, tower cranes, mixing plants and truck

mixers, along with maritime cranes for the Brazilian market. Liebherr Aerospace Brasil Ltda. specialises in precision processing, surface treatment and assembly of high-tech parts for flight control and actuation systems, air management systems and landing gear systems for the aviation industry.

Now, the group is planning further investments to expand the production of large diameter bearings, which can be used as key components for blade and jaw adjustment in wind turbines. With an additional production area of 6,000m² on the Guaratinguetá site in Brazil, Liebherr extends the international production network for components.

"We maintain close cooperation with our customers and business partners. Therefore, we focus on proximity to the leading manufacturers of wind turbines also with regard to the production of large diameter bearings in Guaratinguetá. At the same time, we see vast potential in further development of the South American market and other branches of

industry," says Oliver Wennheller, Sales Manager for Large Diameter Bearings and Wind Industry at Liebherr-Components AG.

The modern machine pool at the production site as well as the extensive know-how of the employees at Liebherr Brasil Ltda., guarantee high-quality components from Guaratinguetá. All future production workers on the Guaratinguetá site have been trained and instructed in the use of

the technical equipment accordingly by Liebherr in Biberach (Germany) and Monterrey (Mexico). The machine pool extends from facilities for the machining and inductive hardening of bearing raceways through Liebherr machines for milling the gears of slewing rings to surface coating. Production will now commence with various product qualifications, so that the first large diameter bearings will be delivered to customers in the second half of 2016.

The large diameter bearings measuring up to 4,500 mm in diameter are mainly designed for use in wind turbines for the adjustment of both rotor blade and azimuth pitches. “We call upon the same high quality standards for large diameter bearings as on our production sites in Germany and Mexico. In this way, we can guarantee reliability and efficiency of bearings during their entire life cycle,” says Karl Glaser, Head of Business Unit Large Diameter Bearings at Liebherr-Components Biberach GmbH.

The Mercom Capital Group expects an additional 5 GW of PV capacity to be installed in 2016, which would make solar energy the fastest growing generator of renewable energy in India...

India has one of the fastest growing solar markets in the world. According to the Mercom Capital Group, a total of 8.1 Gigawatts (GW) of photovoltaic (PV) capacity had been installed in the country by

August 2016, and 21 additional GW are already in the pipeline. These figures present the ideal backdrop against which to hold Intersolar India. From October 19–21, around 230 exhibitors – 15% more than last year – will showcase their products and services to visitors at India’s largest exhibition and conference for the solar industry. Since the Indian prime minister, Narendra Modi, declared energy a top priority, the solar market has boomed. The country has already implemented numerous projects, while many more are currently underway or at the planning stage. The Mercom Capital Group expects an additional 5 GW of PV capacity to be installed in 2016, which would make solar energy the fastest growing generator of renewable energy in India.

25 years of Intersolar This year, Intersolar is celebrating its 25th anniversary. Having started

life as a student initiative in 1991, over the years, it has established itself as a global source of inspiration and catalyst for the industry. Intersolar India is joining in with the celebrations and has prepared a few new features for its visitors to mark the anniversary. For example, the Intersolar India Business to Government Forum is being launched this year (Oct. 19, 11:30am–1:00pm, hall 1) to give company representatives the chance to discuss the latest industry challenges with political decision makers. High-profile speakers, such as Dilip Nigam, Director of the National Solar Mission at the Ministry of New and Renewable Energy, and Veena Sinha, Director at the MNRE, have already confirmed their attendance.

The Buyer Seller Forum, which is also new for 2016, gives Intersolar India exhibitors the opportunity to meet potential clients in a designated

pavilion. Company representatives can use the platform to convince future clients of their products and services.

Intersolar India accompanying program A central focus of Intersolar India is smart renewable energy, which

refers to the combination of energy generation, storage, grid integration and energy management. The Presentation Stage in hall 1 will shine the spotlight on the topic on October 20. To find out more, visitors can attend presentations. A further highlight on the Presentation Stage is the talk by Sushil Reddy, a graduate of the IIT Bombay Energy Science Department. In summer 2016, he traveled 7,000 km through five Indian states on his solar-powered electric bike to raise awareness of the potential of solar energy.

Two important award ceremonies will be held at Intersolar India 2016. The Solar Today Awards 2016 will be presented at 11:00am on October

21 (Presentation Stage, hall 1) by global business magazine Solar Today. The prize pays tribute to companies that perform pioneering work for the solar industry and is awarded in 16 categories.

Storage >>

For the home electricity supply of the future, most experts currently assume that new types of storage will come into wide use. The Fraunhofer Institute for Solar Energy Systems ISE is now working on two research projects to address the aspects related to the acceptance and dissemination of the lithium-ion battery technology…

In 2016, more than 35% of our electricity will come from renewable energy sources. Increasing the flexibility of the energy system through storage systems is therefore being addressed by science

and industry at all levels. One focus is the development of storage solutions based on lithium-ion batteries for private households. These batteries are especially efficient and durable. To date, however, adequate standards and testing procedures do not exist for this technology. The Fraunhofer Institute for Solar Energy Systems ISE is now working on two research projects, which address the aspects related to the acceptance and dissemination of the technology. The German Federal Ministry for Economic Affairs and Energy (BMWi) provides funding for both projects.

For the home electricity supply of the future, most experts currently assume that new types of storage will come into wide use. Particular focus is on lithium-ion batteries, which have a longer lifetime, better efficiency, higher provision of services and require less space compared to conventional lead-acid batteries. Besides their use in electric mobility applications, lithium-ion batteries are gaining popularity for use in stationary applications (grid-coupled and grid-independent). Synergy effects can be realized here that quickly lead to economies-of-scale effects although the storage requirements for the two applications differ.

Safety, a central issue for lithium-ion batteries, depends on different factors weighted according to the application. Heat localized over a small area at defects will dissipate slowly and can lead to material failure or fire in the worst case. There are many different approaches to ensure safety. The basic prerequisites are the selection of cells with high quality, a reliable battery management system and an efficient thermal management. Fraunhofer ISE has been working on lithium-ion battery research for many years. "Whereas lead-acid batteries have been tested in the practice for many years, lithium-ion batteries must first prove themselves in stationary applications in order to win the trust of consumers. Long-term experience is not yet been

available and therefore cannot be applied,” says Dr. Matthias Vetter, Department Head of ‘PV Off-Grid Solutions and Battery System Technology’, at Fraunhofer ISE.

Project ‘SafetyFirst’: Safe Grid-Supportive Storage for Households

In the joint research project, Fraunhofer ISE partners with the Karlsruhe Institute for Technology (KIT) and the Center for Solar Energy and Hydrogen Research (ZSW) to investigate the current safety, quality and grid suitability of commercial electricity storage systems for households. In the ‘SafetyFirst’ project, the scientists will develop recommendations for manufacturers, standardization bodies and authorities based on their investigations on commercially available home storage systems for self-produced electricity. “Grid-supportive home storage systems based on lithium-ion batteries are becoming increasingly inexpensive and thus more attractive for the end user. Up to now, however, standardized, verifiable criteria for assessing the efficiency and safety of these systems has been lacking. In the project ‘SafetyFirst’, our goal is to couple the safety guidelines for lithium-ion home storage with commercially available PV home storage systems in order to prepare future standards,” explains Stephan Lux, Team Leader at Fraunhofer ISE.

In the project, twenty grid-supportive home storage systems undergo long-term tests, carried out on test rigs that imitate the actual operation in private households. Using special load profiles, it is not only possible to analyze the safety of new batteries direct from the factory but also at later aging stages. Data is collected on the safety properties, changing efficiencies and the expected lifetime of the storage systems. Complementary to the analyses on the home storage systems, singular lithium-ion battery cells are selected and analyzed at Fraunhofer ISE and at ZSW.

Fraunhofer ISE analyzes and evaluates the aging properties of various cell types and the entire system in parallel. With this acquired knowledge, information about aging and safety can be collected in the future by merely performing short investigative tests. Based on the results in the laboratory, the research team compiles recommendations

so that the properties of modern lithium-ion batteries are factored into the standards, test specifications and funding.

Project ‘SpeiSi’: Safety of Stationary Storage Systems for Solar Electricity

Fraunhofer ISE is additionally working on a research project, headed by TÜV Rheinland, on the topic of safety and reliability of PV systems with storage. The project ‘SpeiSi’ investigates the safety of such systems, which are installed mainly with the aim of increasing self-consumption. In cooperation with TÜV-Rheinland, the German Section of the International Solar Energy Society and the Center for Solar Energy and Hydrogen Research (ZSW), weak points in the handling, installation and operation are analyzed within the project. “Existing regulations for stationary battery systems consider separate battery rooms for systems with emergency or back-up power or for systems with an uninterruptable power supply,” says Hermann Laukamp of Fraunhofer ISE.

“The regulations must be adapted to accommodate a broader use of stationary energy storage with higher energy content like lithium-ion batteries in private homes,” supplements Georg Bopp, Team Leader at Fraunhofer ISE. Beyond, criteria for determining the performance of PV storage systems, among other things, shall be developed, allowing further information about the quality of the energy management to be gained.

Laukamp and his colleagues at Fraunhofer ISE are investigating three aspects affecting the safety of stationary PV storage systems. For one, a study was carried out on suitable storage technologies and their respective potential hazards. Secondly the probability of light arcs developing in the system and their detection – or better yet the avoidance thereof – was investigated. Thirdly the behaviour of switching and safety devices undergoing pronounced cyclical stress was analyzed. In particular, the researchers would like to find out if the electrical connections become weaker in the course of time, which would lead to a higher fire risk.

Research & Development >>

The U.S. Department of Energy’s ARPA-E has awarded $3.5 million in funding to a team that will be used to develop novel membranes and lithium-metal anodes for the next generation of high-energy-density, low-cost batteries...

Founded and led by some of the battery industry’s foremost inventors, scientists and entrepreneurs, 24M is headquartered in Cambridge. The U.S. Department of Energy’s Advanced Research

Projects Agency-Energy (ARPA-E) has awarded $3.5 million in funding to a team that includes 24M, Sepion Technologies, Berkeley Lab, and Carnegie Mellon University. The funds will be used to develop novel membranes and lithium-metal anodes for the next generation of high-energy-density, low-cost batteries.

According to the ARPA-E Announcement: 24M and team will use nano-composite organic-inorganic protective layers to enable reversible lithium metal electrodes and low-cost, high-energy batteries based on those electrodes. The team’s core innovation takes advantage of the interfaces between the polymer and inorganic components to provide the necessary dendrite blocking ability of ceramic-based conductors while still being highly conductive and manufacturable using traditional roll-to-roll processes.

Carnegie Mellon University energy experts Venkat Viswanathan, Assistant Professor of Mechanical Engineering, and Jay Whitacre, Professor of Engineering and Public Policy and Materials Science and Engineering, are involved with the R&D activities.

24M’s core technology is semisolid lithium-ion, a new class of lithium-ion batteries that will be initially deployed in stationary storage. With this ARPA-E program, 24M and its partners will extend the capabilities of semisolid electrodes to ultra-high-energy density cells that use lithium-metal anodes. Lithium metal is recognized as an enabler of high-energy density in rechargeable batteries, but has heretofore not been sufficiently stable for aggressive long-life applications. 24M and its partners have identified a new approach for stabilizing the lithium-metal anode, which, when combined with the inherent cost advantages of semisolid lithium-ion technology, can realize the energy-density promise of lithium metal, safely and at low cost.

More technically, when charged repeatedly, lithium-ion batteries run the risk of overheating, and even catching fire. This is due to the formation

of dendrites, or microscopic fibers of lithium that can form during the charging cycle. Over time, these dendrites can grow long enough that they connect the battery’s electrodes to one another, causing the battery to short-circuit and become a potential hazard. In order to fully implement future lithium-ion battery technologies, which could greatly increase the battery power of our smartphones, electric vehicles and more, engineers need to find a way to stop these dendrites from forming.

Viswanathan’s project will focus on the use of nano-composite protective layers in low-cost, high-energy lithium batteries. In collaboration with 24M Technologies, Inc., Lawrence Berkeley National Laboratory and Sepion Technologies, the project will leverage the interface between polymers and inorganic compounds to provide the dendrite-blocking capabilities found in ceramic conductors, while maintaining high conductivity and manufacturability. Viswanathan’s portion of the project will focus on the computational study of inorganic compounds to provide the

basis for the optimisation of organic-inorganic protective layers.Whitacre, along with collaborators from Tufts University, CUNY

Hunter, and Massachusetts-based company Ionic Materials, will optimize a new solid electrolyte made of polymer material, created by Ionic Materials. Their project, titled “Novel polymer electrolyte for solid state lithium metal battery technology,” aims to maximize the potential of this new material to enable a battery to endure hundreds of charging cycles with no dendrite formation. The team will use computer modeling to maximize desirable traits, such as life cycle and energy density, while ensuring a final product that is low-cost and manufacturable.

“By implementing new polymers that fight the formation of dendrites and enable the use of pure lithium metal electrodes, a more energy dense and safer lithium ion battery system is possible. This could lead to both a greater degree of safety, and more energy in the same size battery package,” says Whitacre.

ARPA-E looks to drive innovation by providing funding for high-impact energy technologies that are in stages too early for private investment. In total, Carnegie Mellon will receive over $1 million in funding from ARPA-E, expected to begin in the fall of 2016.
