Abstract

With the total 600MW power production capacity, Kriegers Flak will be the largest offshore wind power plant (OWPP) in Denmark. Kriegers Flak will utilize the two unequal sections, 400MW and 200MW, on the two offshore platforms interconnected via a 9 km 200kV cable and connected to the onshore substation via two 80 km 220kV cables. From the onshore 220kV substation, the 220kV connections continue to the two different 400/220kV substations of the Danish transmission grid. From the 400MW offshore platform, the connection continues to the 150kV offshore infrastructure of Germany. The Kriegers Flak grid connection resamples a meshed offshore grid (MOG) which increases complexity of and requirements to its overall voltage and reactive power control. This presentation describes how the overall voltage and reactive power control system is proposed and designed for optimized operation and reduction of the stress and efforts on the control equipment of the Kriegers Flak 220kV system.
