Under the motto "Future comes as standard", the 64th

International Auto Show (IAA) will open its doors in

Frankfurt, Germany from September 15 to 25, 2011.

This year‘s show will focus on electric mobility. With the

"Ecosystem Electric Mobility" in Hall 4, there will be for

the first time an exhibition area offering a comprehen-

sive overview of all aspects of electric mobility, so that

visitors and exhibitors can engage in intense dialog.

The program will also include a specialist convention

of the same name, bringing together all the leading

vendors from all the industries involved.

For Siemens, the IAA 2011 is all about integrated elec-

tric mobility. Siemens is taking this opportunity to pre-

sent its "Boulevard of the Future" at IAA Hall 4.0, Booth

B 19. This will give visitors an insight into the extensive

product portfolio by means of interactive modules. The

portfolio ranges from components for the electrical

powertrain, through suitable charging infrastructure,

all the way to customized software solutions. This posi-

tions the "Boulevard of the Future" as the IAA interface

between automobile manufacturers and energy ven-

dors, and makes it immediately accessible to visitors.

You can find more detailed information on the Siemens

presence at the IAA shortly at

IAA 2011: With the "Boulevard of the Future" Siemens is backing electric mobility

Electric mobility in practice

Siemens is investigating the suitability of electric

vehicles for daily use nationwide with its internal

pilot project, Project 4-S (4Sustainelectromobility).

Siemens employees have been testing a fleet of 100

vehicles since November 2010. As well as garnering

more precise knowledge of how the vehicles behave

in use, the aim of the project is also to gain sound

information on possible vehicle and infrastructure

requirements. With this field experiment, Siemens

is underlining its integrated approach to the future-

oriented market of electric mobility.

All-round efficiency concept pays offThe energy requirements of an industrial plant

can best be reduced by applying a holistic concept

based on the phases identify, evaluate and imple-

ment. All the optimization phases have to be con-

verted into technical solutions, and all the energy-

relevant components of the plant have to work

together perfectly, especially those in the drive

trains. This is because drives consume two thirds of

the electricity used in industry.

In order to reduce the energy requirements of an

industrial plant, the energy consumption of the plant

must first be determined. The Siemens Sentron ran-

ge provide the right measuring instruments for this

task. Visualization and analysis are handled by energy

management software solutions, such as the Siemens

"Simatic powerrate". The "energy guzzlers" are often

found to be drive components. Therefore, in the next

step, the drives are evaluated using the Siemens "Sina-

Save" evaluation software tool. It analyzes plant and

application-specific characteristics such as the individu-

al operating times, delivery rates and delivery profiles

of the plant components under investigation. From this

data, the tool calculates the actual savings and states

how quickly investing in an energy-efficient motor

will pay off in network operation or with a frequency

converter for variable speed operation. The calculated

savings potential is then put into practice in the final,

implementation phase. In order to fully realize this po-

tential, especially in the drive systems, all parts of the

plant have to work together optimally with the com-

ponents of the drive train, as well as with the plant's

automation, communication and control equipment.

Selecting suitable components is the key to achieving

the highest possible energy efficiency. The initial focus

is on the motor, the heart of a drive system. The effici-

ency of motors can be considerably increased by design

measures and by using specific combinations of materi-

als. The operating mode of the motors is also a decis-

ive factor in determining the efficiency of the overall

system. For example, it pays to run a motor at a variab-

le speed controlled by a frequency converter, especially

in pump and fan applications. Under partial load, these

devices, such as those in the Siemens Sinamics range,

continuously match power consumption to the actual

requirements. This avoids energy being wasted which,

in turn, enables savings of up to 60 percent to be achie-

ved. The other way of saving energy with frequency

converters is through regeneration.

Their high savings potential makes drives the key to an

energy-efficient plant. In order to achieve the maxi-

mum possible energy efficiency for a whole plant,

the drive systems have to be fully integrated into the

factory automation environment. This is the only way

for all phases of the energy management system to

intermesh perfectly.

Economical pumps

The economic and ecological balance of a combined

heat and power plant can be substantially improved

by using energy-efficient drive systems. The Stadt-

werke public utility in Chemnitz therefore operates

the cooling water and district heating pumps in its

combined heat and power plant in variable speed

mode. This has cut energy requirements to a mere

fraction of their former level.

The Chemnitz combined heat and power plant supplies

the city's 240,000 residents with reliable and environ-

mentally acceptable electricity and district heating. It is

an ecologically acceptable solution because the com-

bined heat and power cycle allows the steam used to

generate electricity to be used again in a downstream

phase for heating water. The hot water then passes

through an extensive network of pipes to provide dis-

trict heating to a large number of residents who use it

for heating and hot water. There is considerable poten-

tial for making savings in the pumps which transport

the district heating water or, to put it more precisely, in

the drive systems of the pumps.

As the demand for district heating fluctuates very wi-

dely, the Stadtwerke Chemnitz decided to convert the

flow control system for the hot water circulation pumps

from a hydrokinetic coupling to speed control with

frequency converters. The objective was to optimize

the power plant's internal energy balance, because the

pump drives had always run at the speed producing the

maximum delivery rate, although this was not really

necessary.

The use of the right motor-converter system enables

the speed of the hot water circulation pumps to be

adjusted to provide exactly the required delivery rate.

In this way, the frequency converter only consumes the

amount of energy that it actually requires at any given

moment, which can reduce the energy requirement

by some 35 percent. In Chemnitz, the drive system

uses Siemens type N 690 kW low-voltage motors and

Sinamics G150 frequency converters. The latter are re-

liable, quiet and ideal for single drives, such as pumps,

which do not require line regeneration.

The Stadtwerke Chemnitz exploits the advantages of

frequency conversion for its district heating pumps and

its cooling water pumps and benefits from an energy-

efficient, precise operating mode that places less stress

on plant components. As the drive system operates

on medium voltage due to the higher power ratings

involved, Siemens type H compact high-voltage motors

are used. The motor speed is controlled by Siemens

Robicon Perfect Harmony medium-voltage converters

which can be brought into operation on-site quite

simply on the plug-and-play principle, without needing

assembly units.

Variable speed operation has other advantages in

addition to saving energy. Delivery rates can be adjus-

ted considerably more quickly and precisely to current

demands. The mechanical systems along the entire

drive train start and stop softly, thus reducing wear and

maintenance expenditure and extending the service

life of the components. Furthermore, the Stadtwerke

Chemnitz no longer has to worry about pressure waves

in the pipe network.

Robust low and high-voltage motors provide the basis for smooth operation of the pumps in a combined heat and power plant.

Training: close to the real worldThe Bildungswerk der Niedersächsischen Wirtschaft

(BNW - the Vocational Training Institute in Lower

Saxony) aims to provide first-rate and, above all,

practical advanced training and retraining courses.

The BNW has recently acquired a DMG machine for

simultaneous five-axis machining, state-of-the-art

CNC technology and ten CNC training stations with

identical controllers.

As the largest and most important training provider in

Lower Saxony, the main task of the BNW is to prepare

people with different educational backgrounds for the

work they will be expected to do in companies. This in-

cludes, in particular, aligning the training content closely

with requirements in industry.

This is exactly what the metalwork shop in Lüneburg, a

branch of BNW, has achieved. Investing in two new DMG

machine tools – both equipped with Siemens high-end

CNC Sinumerik 840D sl – has enabled BNW to provide

practical training on machines similar to those installed

in many companies in Lower Saxony. Conventional

three-axis machining as well as 3+2-axis and simultane-

ous five-axis machining can all be taught on the DMU50

DMG milling center, which is equipped with five NC

axes.

Only if the employees of the companies know how to

exploit the potential of modern machines will they be

economically successful and satisfied in the long term.

This also includes being able to deal with controllers.

The Sinumerik 840D sl offers not only fast block exe-

cution and short cycle times, but also a modern user

interface. The latter has proven to be especially useful

because operation is easy to learn and largely self-ex-

planatory. Even employees without CNC experience can

quickly learn how to use it, and create simple programs.

If anything remains unclear after completing a course

of advanced training at BNW, the Help button will open

an easy-to-understand help menu on the operator's own

workstation.

The BNW in Lüneburg has bought ten SinuTrain licenses

for PCs and obtained certification as a training partner

so that it can better explain the features of turning and

milling programming in the classroom. Training on a PC

is in such high demand that more licenses have been

ordered. The workstations are laid out identically to the

workstations on the machines. When a trainee has com-

pleted his program, machining

can be virtually executed as a

3D graphic on the computer.

This enables mistakes to be

seen quickly, without wasting

expensive material. Finally, the

trainer tests the program and

transfers it via LAN link or USB

stick directly to the machine,

which promptly produces the

desired workpiece.

The BNW Lüneburg Training Center uses Siemens CNC Sinume-rik 840D sl for practical training purposes.

Siemens has received an order from Austrian com-

pany voestalpine Stahl GmbH to modernize the

main drives on the hot strip mill at voestalpine Stahl

in Linz. This will upgrade the drive control system to

the state of the art and integrate it into the existing

automation environment. Modernization will take

place stage-by-stage during short maintenance

shutdowns and is scheduled to be completed in the

spring of 2013.

After conversion, the hot strip mill belonging to voe-

stalpine Stahl in Linz will be able to produce 4.8 million

tons of hot-rolled strip per annum, in thicknesses ran-

ging from 1.5 to 20 millimeters, and in widths between

700 and 1,750 millimeters. The plant has a roughing

stand with an edger and a finishing mill with seven,

four-high stands. All eight stands are equipped with

Siemens double-motor drives.

The 16 synchronous drives, which feature cyclocon-

verters and Simadyn D controllers, will be fitted with

new Sinamics control components. The existing power

modules of the converters will be retained. This will

make the roll mill drives state-of-the-art without having

to completely replace the converters. Siemens will also

be responsible for configuration, detailed engineering,

installation and commissioning.

The award of this order had been preceded by the suc-

cessful piloting of the modernization concept on one

drive in the finishing mill in December 2010.
