根据脉动风速的功率谱和相干函数,采用谐波合成法(HSM),实现了对近海风力机脉动风场脉动风速时程的模拟。在此基础上,结合动量叶素理论对风机气动性能的计算结果,得到由脉动风场引起的风力涡轮机的随机空气动力荷载,为海上风力机支撑结构的动力反应计算提供了外部荷载。 According to the power spectrum and the coherence function of the pulsating wind speed, a harmonic synthesis method (HSM) was used to simulate the fluctuating wind speed time history of the wind farm fluctuating wind field. Based on this, the random aerodynamic load of wind turbines caused by pulsating wind field is obtained by the calculation of the aerodynamic performance of fan with momentum valence factor theory, which provides an external load for the dynamic response calculation of offshore wind turbine support structure.
