Kriegers Flak Combined Grid Solutions (KF CGS) HVDC

Integrating renewable power and enabling energy trade between Denmark and Germany SOV, (Denmark) and 50Hertz Transmission GmbH (Germany) have awarded Hitachi ABB Power Grids a contract to supply a complete turnkey, back-to-back converter station.

This 410 MW HVDC station connects the Kriegers Flak offshore-grid to the German grid in Bentwisch, northern Germany. The HVDC system will help secure the energy supply in Denmark as well as support energy trading with Germany and integrate four offshore wind farms.

Hitachi ABB Power Grids will design, engineer, supply and install the converter station, including high-voltage equipment such as power transformers, converter valves, cooling systems and a state of the art MACH control and protection system.

HVDC Light® technology provides sophisticated features to the network such as the “black-start” power restoration capability and exceptional power control, to regulate the system with changes in the wind speed.
