摘　　要：漂浮式风电机组存在平台六自由度运动,使得风电机组气动特性的非定常性显著。本文采用自由涡尾迹法对NREL 5MW风电机组的气动特性进行了模拟。为了能清晰比较单个平台运动对气动性能的影响,将浮式平台的纵摇、纵荡以及横摇运动简化为给定的正弦函数,研究了不同振幅的平台纵荡、纵摇、横摇运动以及两者和三者之间耦合运动下风电机组的气动功率和推力变化。结果表明:浮式平台的运动会导致风电机组功率和推力的波动,平台纵摇运动影响最大,横摇运动的影响最小;较剧烈的耦合运动会显著增加平均发电量;平台三自由度耦合运动中,增大纵荡振幅可以增大平均功率输出,并减少平均推力。The floating wind turbine has six degrees of freedom movement of the platform,which makes the aerodynamic characteristics of the wind turbine significantly unsteadiness.In this paper,the aerodynamic characteristics of NREL 5MW wind turbine are simulated by free vortex wake method.In order to clearly compare the influence of single platform motion on aerodynamic performance,the pitch,surge and roll motions of floating platform were simplified as given sine functions,and the aerodynamic power and thrust of wind turbine under different amplitude of platform pitch,surge and roll motion and their coupling motions were studied.The results show that the motion of floating platform causes the fluctuation of wind turbine power and thrust,and the platform pitch motion has the greatest influence,while the roll motion has the least influence.The more intense coupling movement significantly increases the average power generation.Increasing the amplitude of surge can increase the average power output and reduce the average thrust in the three coupled motion of the platform.
