随着大型海上风电场的建设逐渐从浅海向深海发展，浮式风电机组已成为各国海上风能开发的热门话题。传统的固定式基础已不能满足海上风电机组的性能要求。本文设计了一种三柱式半潜式浮式风电机组的基础结构，并考虑到海上平台和陆上风电机组的特点，利用海洋工程商业软件SESAM对半潜式平台的完整稳性和破损稳性进行了数值分析，主要研究了当平台倾斜角度较大、舱室破损倾斜时，浮式风力机是否会倾覆。仿真结果表明，当一舱或两舱破损时，浮式风力机不会倾覆，风力机能保证正常发电。
With constructiodn of the large-scale offshore wind farm developing gradually from the shallow sea to the deep sea,floating wind turbines have become a hot topic of offshore wind energy development in many countries.The traditional fixed type foundation can not meet the performance requirements of offshore wind turbines.This paper designs a triple-column semi-submersible as the foundation structure of floating wind turbines,and considering the characteristics of offshore platforms and wind turbines on the land,the commercial software SESAM for ocean engineering is used to do a numerical analysis on intact stability and damaged stability of the semi-submersible platform.The paper is mainly concerned with when the platform is inclined with a large angle and when the cabin is damaged to incline,if the floating wind turbine will overturn.Simulation results show that when one cabin or two cabins damage,the floating wind turbine will not overturn.The wind turbine can guarantee normal power generation.
