Power Conversion builds customized solutions

to meet your specifi c space requirements

Examples for possible arrangements for each kind of topology

which reflected pumped storage power plants with variable

speed approach. Needed space inside the power plant is strictly

connected to the specific requirements on our equipment and

design of the machine set. Power Conversion is investigating

and checking all relevant data to provide the best solution to fit

in the appropriate rooms for green field and brown field projects.

Power Conversion uses rugged, robust press-pack IGBT

technology, which is superior to standard grade IGBT

technology. Press-pack IGBT yields better surge current

rating, improved thermal cycling and longest lifetime.

Press pack IGBTs do not use failure prone bond wires.

Power Conversion’s control technology supports different

algorithms for line side control, as well as various operation

modes that are required by grid operators around the world.

Extensive expertise in

variable speed projects for hydro

With our variable speed drive technology, pumped storage plant

operators are better able to meet the need for peak supplies

of power while in turbine mode. Also, the plant achieves higher

efficiency levels in partial-load conditions because the machine

speed can be adjusted to meet the grid’s changing power

requirements while maintaining the turbine close to its highest

efficiency point. At last operators have greater control over the

plant’s performance in pump mode, by being able to control

the power consumed from the grid while refilling the upper reservoir.

However, in order to react to changing wind and solar power

conditions that can undermine grid reliability, pumped storage

power plants need to have greater flexibility and shorter

response time. Reversible pump turbines with variable speed

motor-generator provide adjustable discharge and power in

both turbine and pump operation, plus enhanced grid services

like virtual inertia.

Engineered solutions for complex drive and control applications

PROVEN DRIVES CONTROL TECHNOLOGY

If you currently rely on vintage SFC drive controls like

VME or Syconumdrive controller, you cannot ignore

the risk of obsolescence. A reliable and cost-effective

upgrade can save you the time and expense of a

complete system’s replacement.

This simple upgrade will modernize your controls and

data interfaces, substantially improving control

capabilities and performance. Extensive diagnostics

and comprehensive testing can make systems easier to

maintain, with GE’s outstanding drive services helping

you get the greatest possible value from your MV drives’ controls.

The external control interface -GE’s P80i Control

System toolbox-is widely considered as one of the best

tools for configuring, troubleshooting and maintaining

legacy SFC drives and controls.

IMPROVED CONTROL CAPABILITIES & PERFORMANCE

A well planned and executed upgrade by GE Power

Conversion experts can save time and cost of an

extensive system replacement and help you extend the

life of critical power equipment.

The Intellix™ MO150 transformer monitoring system, from GE Energy, is an intelligent, cost-effective

solution which provides comprehensive monitoring and interactive transformer condition diagnostics,

to provide early warning of incipient failure conditions.

Based on field-proven technology, the Intellix MO150 uses various sensors such as the Hydran™ and

state-of-the-art transformer mathematical models based on IEEE® or IEC® standards, to provide real

time information on the overall performance of the transformer to assist utility operations managers

and system operators in making critical decisions.

Key Benefits

On-line monitoring and performing real-time, transformer diagnostics can help reduce the risk of

unexpected and sometimes catastrophic failures. This also helps you avoid expensive replacement

and clean-up costs, unplanned downtime and overall improvement in asset. Reliability. Early detection

of potential transformer problems is vital tothe lifespan extension of critical transformers and brings

significant business and operational benefits:

• Reduce inspection and maintenance costs by confidently stretching out the time between routine

maintenance activities

• Optimize equipment life by monitoring cooling system performance

• Reduce the probability of an unplanned outage with continuous condition monitoring

• Provides greater lifespan confidence through the use of on-line model computation providing real

time transformer condition information

• Defer major replacement costs by optimizing your transformer’s performance and extending its

lifespan
