Abstract

Abstract: With the continuous increase in the capacity and scale of offshore wind power units，the limitations of

conventional 35kVAC power collection schemes emerge，which are fewer interconnection wind turbines，longer submarine

cables and increasing costs per unit. A 66 kV AC power collection scheme with a high voltage level is proposed. Compared

with the 35 kV AC power collection scheme，it has more technical and economic advantages. It can not only transmit large

capacity power，but can also save investment and operating costs. The equipment for 66 kV AC power collection scheme is

investigated and its prospect is discussed in combination with the development trend of offshore wind power.

Key words: offshore wind power, AC current collection, voltage level, submarine cable, 35 kV, 66 kV
