Effects of three-dimensional wind field parameters on aerodynamic loads and tower base loads of a floating offshore wind turbine

为研究三维风场参数对风机气动载荷和塔基载荷的影响,基于浮式风机一体化耦合分析方法,采用NREL 5MW风机和OC4-DeepCwind半潜式浮式风机基础作为分析对象,分别选取不同的风速和风向参数,对浮式风机的整体动力响应进行计算,得到气动载荷和塔基载荷随参数变化的响应结果。分析结果表明,风速和风向均对浮式风机的气动载荷和塔基载荷有显著影响。

This paper focuses on the effects of three-dimensional wind field parameters on the aerodynamic loads and tower base loads.Based on the integrated coupling analysis method of floating offshore wind turbine,the NREL 5MW wind turbine and the OC4-DeepCwind semi-submersible floating structure were used as the analysis objects.The overall dynamic responses of the floating offshore wind turbine were calculated with different wind speeds and wind directions,and the aerodynamic loads and tower base loads were obtained.The analytical results show that both wind speed and direction have significant effects on the aerodynamic loads and tower base loads.
