摘　　要：海上风电机组工作环境复杂、恶劣。热带气旋影响海域,极端环境条件作用往往导致结构的失效破坏。工程设计中往往遵循规范建议的传统方法,简单选取极端海况组合作为校核条件。本研究拟采用数值模拟、概率分析、灰色预测结合的方法,建立嵌套模型对热带气旋诱发的极端海况对风电机组支撑结构的作用进行分析。结果表明该方法合理,并可应用于热带气旋作用下海洋结构整体可靠度计算。The offshore wind turbine system works in the severe sea states.Especially in the regions which influenced by tropical cyclones,the extreme sea states induced by storms will lead to the structure failures and make large losing.At present in the field of engineering,the combination of wind,wave and current with some return period is selected according to the design code for the response analysis of structures.In this study,numerical simulation,probability analysis and prediction based on theory of grey system are used to propose a nested model for the reliability analysis of offshore wind turbine system.Using the nested model,the influence of tropical cyclone to the offshore wind turbine system in the South China Sea is analyzed.According to the calculation result,the reliability analysis of offshore wind turbine system can be performed.
