AC-CONNECTION OF AN OFF-SHORE WIND-PARK TO AN ON-SHORE ELECTRICITY GRID AND BOOSTER TRANSFORMER FOR PROVIDING SUCH AN AC-CONNECTION

摘要

The present invention relates to an AC-connection comprising an off-shore platform, an on-shore substation coupled to said off-shore platform, a sea-cable coupling said off-shore platform to said on-shore substation, said AC-connection coupleable or coupled to an on-shore electricity grid with a high-voltage switch-gear wherein, said off-shore platform comprises an electricity grid operating at medium voltage, a wind turbine generator, coupled to said electricity grid, a shunt reactor, coupled to said electricity grid operating at medium voltage, a power step-up transformer, positioned between said electricity grid and said sea-cable, so that said active and reactive power production capabilities of said AC-connection provide a plant capability curve as imposed by said on-shore electricity grid.
