Discussion on Structural Design Method of Offshore Substation

According to the established offshore wind power development goal of National Energy Administration, about 100 offshore substation platforms will be built until 2020 which means large construction scale of offshore substations will appear in China. "Offshore substation"(OSS) epitomizes the combination of electrical engineering and ocean engineering, what becomes the key issue of developing offshore wind power is to build OSS for transmitting electricity power generated by offshore wind farms. This paper shows ideas, principles, contents of OSS structural design and then puts emphasis on design considerations and analysis contents of different OSS structural design stages, provides a set of feasible method for structural design of Offshore substation.
