Pretact® – React in advance Keeping grids resilient - at all times

General introduction

The Siemens resilience concept, named Pretact®, for resilient grids comprises a three-pillar-plan to enable our customers to prevent failures, protect their equipment and react in cases of emergency and any other kind of bypasses.

Customer challenge

• Network outages due to maintenance or transformer failure

• It takes too much time to order a spare / replacement unit


Pretact® – React in advance Keeping grids resilient – at all times

Save time & money while enjoying perfect peace of mind in terms of grid resilience

The concept

• A comprehensive concept to increase grid resilience & network availability

• To prevent, protect and react at the entire energy value chain (end to end)

• Modular feature & solution architecture to meet almost all regional or application needs, combining approved technologies and latest innovations

• The right choice for emergencies, retrofit, upgrades and new installations for your intermediate or long-term solution to network stability challenges

• Ecofriendly transformers for highly populated as well as rural areas


Pretact® – Bypass transformers Keeping grids resilient – at all times

Beneficial solution for the customer • Installation time: within the shortest possible time instead of

weeks • Dimensions & weight to meet transportation limits • Cost efficient solutions for planned and forced

outages • Applicable to all grid structures

Block load flow –

Phase shifters The most efficient device for load flow control


A phase shifter transformer is the most efficient way to control the active power flow in a line of a meshed grid. Load flow control is done, via manipulation of the phase angle between voltage at source side and load side. Even blocking or reversing the power flow is possible.

Customer challenge

• Transmission bottlenecks resulting in overloading of specific lines

• Unwanted power flow from adjacent grid operators through own network

• Unwanted physical power flows not covered by commercial contracts

• Difficulty to reconnect networks with large phase angles

Enforce load flow


Phase shifters Grid stability – Flexibility – Maximized utilization of existing hardware

Beneficial solution for the customer

• Increased power capacity of grid, due to better utilization • Cost efficient solution for power flow control • Grid stability due to avoidance of overloading and additional possibility for

voltage regulation • Independence of adjacent grid operators and protection of own grid from

unwanted loading • Maximized commercial trading possibilities • Reduction / Elimination of loop flows

Siemens highlights

1) value achieved without sound house


Variable shunt reactors Perfectly adapting to changing network conditions


Shunt reactors compensate capacitive reactive power from high voltage lines. While fixed shunt reactors are designed for defined system condition, variable shunt reactors allow continuous adjustment of the reactor power rating via tap changer to actual needs, dependent e.g. on current line loading or active network paths.

Customer challenge

• Volatile line loading e.g. from renewables or demand cycles resulting in voltage fluctuation

• Future network changes – e.g. grid extensions, switch from overhead lines to cable

• Voltage stability and grid efficiency

Variable shunt reactors A profitable investment


• Cost efficient solution for flexible reactive power - Profitable due to reduced reactive power purchase

• Increased grid efficiency • Reduced reactive power loading

- Reduced network losses - Better network voltage control

• Independence of adjacent grid operators • Cheap spare concept if variable shunt reactor is combined with

DC Compensation To overcome the negative effects of half cycle saturation

General introduction Direct current in electric power grid affects the grid’s components in a negative way. Even though this issue is not fully clarified so far the following sources have been identified:

• Power electronics (e.g. SVC substations) • Renewable power generation (wind, solar) • HVDC transmission • Neutral offset by DC drives • DC operated railroad or subway systems Customer challenge • Significant increase in noise level (critical in sensitive

areas w/ high population) • Transformer reactive power rises sharply • Increase of no-load losses

Transformers for urban applications For the challenges of megacities and urban regions

The customer challenge

Customer projects in urban areas need to deal with several challenges:

• Requirements to comply with strict regulations on:

- Environmental safety

- Noise emission

• Maximum reliability and safety in operation

• Maximum usage of applied resources

- Economic value add

- High performance and low losses


Transformers for urban applications For the challenges of megacities and urban regions

Siemens offers unique solutions for the customer

Alternative insulation liquids - Esters • Renewable, eco-friendly and fully biodegradable • Safe & reliable in operation • High acceptance in urban areas and mega cities Low noise • Noise emission compliance becomes more and more important in

urban regions • Siemens low noise transformers comply with the strictest noise

performance requirements Waste heat usage • Waste heat usage maximizes utilization of resources and energy • Allows greater flexibility in site configuration and smaller space

Tank Rupture Prevention A stand alone solution for an additional extra in safety

Our experience from in-depth analysis reveals the critical zones for each individual customer design and finds the optimum extra protection.

Transformer Requirements How to be sure power transformers for working environments with highest security requirements are really safe?

Solution

A detailed static & dynamic simulation and calculation results in an improved tank design according to individual customer transformer requirements.

Advantages • Higher safety for assets and personnel in case of failure

due to rupture prevention measures (e.g. specific tank pressure protection against internal arc’s)

• Same footprint with higher safety, as no external measures are required


Tank Rupture Prevention A stand alone solution for an additional extra in safety

Transformer Requirements How to bring transformer power in sound sensitive proximities without compromising power rating and loss levels?

Solution

• Especially proven for densely populated residential areas.

• Fully compatible with all other Siemens transformer design concepts like Natural Ester and Tank Rupture Prevention

Advantages • Comprising internal and external noise reducing

arrangements thus cutting sound levels by 23.9 dB(A)* at same technical limits

Siemens AG Österreich - Transformers Weiz Application and benefit of bullet resistant transformers

Transformer Requirements The attack on an electric power station in San Jose, California highlighted the threat that high-powered weapons can pose to transformers and reactors. The attack, which was carried out with a high-powered rifle, was able to surgically knock out 17 large transformers in approximately 19 minutes. It took utility workers 27 days to make repairs before reopening the substation

Solution • Polymer concrete panels are capable of withstanding

Class 9 bullets while Class 12 rounds have successfully been stopped from penetrating high-hardness steel sheets

• Mobile/ fast replacement • Other applications possible such as seismic proof,

explosion prevention


Designed to withstand GIC-safe power transformers Transformer Requirements GIC effects on the power grid • Transmission lines and transformers are linked to

geomagnetic field changes • Moderate GIC levels are able to last for several days • Adverse impacts to the transformer

- Increased loss of life due to higher hotspots and gassing

• Worst case: Black out of the power grid

Solution

• Detailed studies of the transformer behavior during a solar storm can be performed

• Special test arrangements in laboratories can be used to verify the GIC strength of power transformers

• GIC risk evaluation with only a few transformer design parameters can be performed


Why highlight Alternative Insulating Liquid

• Meet regulations regarding environment impacts • Siemens provides proven equipment with

appropriate designs • Siemens has been delivering ester units • Distribution Transformers for over 20 years • Power Transformers since 2004 • Committees and publications on alternative
