海上变电站结构设计探讨

Discussion on Structural Design Method of Offshore Substation

按照国家能源局制定的海上风电发展目标,到2020年全国将出现100座左右的海上变电站平台,海上变电站的建设规模巨大。"海上变电站"(OSS)集中体现了电力工程与海洋工程的结合,建设满足海上风电场电能安全稳定送出的海上升压站,已然成为我国发展海上风电必须面临和解决的关键问题。文章介绍了OSS结构设计思路、设计原则及设计内容等,并重点探讨了不同设计阶段OSS结构的设计考虑及分析内容,为OSS结构设计提供了一套切实可行的设计方法。

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.
