DYNAMIC RESPONSE ANALYSIS OF OFFSHORE WIND TURBINE CONSIDERING ROTOR-NACELLE ASSEMBLY (RNA) OPERATION

  • 摘要: 在风、浪的长期耦合作用下,海上风电结构的振动问题不仅会影响发电机组的电能输出,还会加剧结构的累积疲劳损伤,危害结构安全。为更加科学、合理地认识近海风电结构的动力特性,该文通过考虑风轮-机舱组件(rotor-nacelle assembly, RNA)运行作用及风、浪相关性,采用Von Karman风谱模型模拟湍流风场并计算气动荷载,通过莫里森方程求取单桩基础结构的波浪荷载,对NREL 5MW单桩风电塔进行动力响应分析,对比其在不同状态下的动态行为模式;通过批处理程序,开展对近海风电结构在3 m/s~30 m/s风速范围内的响应计算,探究RNA运行作用下近海风电结构位移、加速度响应随风速的变化规律。结果表明:近海风电结构在不同工作状态下的动力响应具有不同的频谱特征,其位移、加速度峰值响应会被RNA运行作用放大。
