| 摘 要： | 台风严重制约着海上风电发展。通过台风影响风机的空气动力学分析，计算作用于叶片、塔筒及风电机组整体风荷载，剖析其强度承载能力。结合IEC 61400和GB/T 31519-2015、GB/T 18451.1-2012等设计标准要求，对风机制造各主要部件成本及现有抗台风手段进行分析，提出调整风机叶片材料强度、增加伸缩式叶片定位机械臂来固定风机叶片、将风机塔筒中部固定螺栓连接改为上部塔筒可下沉式折叠结构以及调整海上风机抗台风控制策略等多项措施增强海上风电机组抗台风能力，以期实现海上风电机组成本低、工程实用性强、抗台风效果显著。

| Abstract: | Different from European offshore wind farm, typhoon seriously restricts offshore wind development in China. Based on aerodynamic analysis of offshore wind turbine in typhoon condition, wind pressure on blade, tower and turbine winding are calculated. Anti-typhoon cost is analyzed with IEC 61400 and GB/T 31519-2015, GB/T 18451.1-2012 standard requirement. Then measures of offshore wind turbine are proposed to improve typhoon resistance. Those measures include strengthen offshore wind turbine blade material, lengthen of retractable blade positioning mechanical arm to fix blade, change central tower structure from bolt connection to subsided upper tower and improved anti-typhoon control strategy. All those measures can help to build cost effective and practical anti-typhoon offshore wind turbine. |
