基于对比分析中国船级社规范《海上风力发电机组认证规范》、日本规范《风电塔支撑结构设计指南·同解说》(2010年版)、国际电工委员会的《海上风力发电机组设计标准》(IEC/TC88 61400-3)、挪威船级社规范“Design on offshore wind turbine structures”(DNV-OS-J101),研究风电机塔架在风荷载、地震荷载、波浪荷载作用下的设计要求。并选用轮毂高度为88.5m的风电塔为算例,由于海洋环境中风荷载、波浪荷载起主导作用,因此对比分析四种典型规范下风电塔在年平均风速和极端风速及其相应波浪荷载作用下的剪力及弯矩,为风电塔结构风荷载、地震荷载、波浪荷载作用下的设计提供指导。
Based on the comparative analysis of the norms of CCS Rules for Offshore Wind Turbine Certification, the Japanese Code of Conduct on Wind Power Tower Supporting Structure Design Guidelines (2010 Edition), the International Electrotechnical Commission’s “Design Standards for Offshore Wind Turbines” (IEC / TC88 61400-3), Det Norske Veritas Design on offshore wind turbine structures (DNV-OS-J101) to study the design requirements of wind turbine tower under wind, seismic and wave loads. And wind tower with hub height of 88.5m is chosen as an example. Because of the wind load and wave load in the marine environment, the wind power tower plays an important role in the analysis of four typical wind power towers under the influence of annual average wind speed and extreme wind speed and their corresponding wave loads Shear and moment of the wind tower for wind power structure, earthquake load, wave load under the guidance of the design.
