GE IS420UCSBH4A - Controller Module, Compact, High-Speed

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.

An SFC provides multiple features, including independent reactive power control for both grids

and the capability to supply the railway from a weak three-phase grid with low short circuit

power, ensuring perfect voltage balancing between phases.

It synchronizes the SFC along the line using the Phasor Management Unit (PMU), such as the

GE Vernova Multilin N60. which assists in balancing power across substations. The system is

protected by protection and control relays like the GE Vernova Multilin Agile. Additionally, it

supervises and manages the entire traction power supply to optimize availability. Faults along the

line are located using Travel Wave Form Localization (TWFL) technology, enabling faster recovery

of line supply.
