Introduction According to the offshore wind farms layout and typical delivery scheme of Guangdong area, the paper discusses the two joint delivery schemes of 300 MW offshore wind farm.
Method From the aspects of electrical single line diagram, submarined cable′s selection, reliability analysis, cable laying and supply, comparable investment and so on were compared.
Result To provide an optimization for the joint delivery of offshore wind farm, setting two 220 kV offshore booster station and one onshore control center, one of the booster station connect to another with one 3×1 000 mm2 submarine cable, then sent out with two 3×1 000 mm2 submarine cable to onshore control center.
Conclusion The scheme of two joint delivery schemes of 300 MW offshore wind farm can save the investment and reduce the area of sea which offers reference for the prospective electrical design of offshore wind farm.
