GE VMIVME-4150 - VMEbus Module, Compact, High-Performance

When investing in a pumped storage power plant, decision

makers identify and define the main requirements the plant

has to fulfill. Reasons may vary, for example with the main

drivers being to produce power from water as a renewable

energy source, to balance the grid or to build a large-scale

energy storage system to help manage the power grid

and security of supply. Investors and decision-makers need

to identify the best technology suitable to meet the project’s

specific purpose.

The PSPP Goldisthal is located in Thüringen (in the east-

southern region of Germany) and has a capacity of 1060MW.

The project has begun in 1997 and produced energy since

2003. There are two variable speed machine sets with

AC-excitation and asynchronous machine and two fixed

speed machine sets with start-up frequency converter and

synchronous machines.

Goldisthal is one of the first pumped storage power plants

where the decision was taken to use the variable speed

technology to improve operation behaviors and increase the

advantages in regard of efficiency in full load and especially

the significant improvement in part load operation.
