DC for Wind Power

The German company TenneT Offshore GmbH is using an 800 MW HVDC Light transmission system to connect offshore wind farms located in the North Sea DolWin1 cluster to the German national grid.

The wind farms will be connected with AC cables to an HVDC Light converter station installed on an offshore platform in the North Sea. The turbine-generated power will be transformed there and transmitted via a 75 km long DC undersea cable, then a further 90 km long land cable to an onshore HVDC converter station at the grid connection point. The HVDC Light system from ABB has a total capacity of 800 MW at ±320 kV.
