摘　　要：通过观测的风速数据拟合出风速的威布尔分布曲线,了解风资源的分布情况。并根据风的随机性建立风速变化模型,应用Matlab软件对风速波形进行仿真,进而建立变桨距风机转子的仿真模型。了解在最大风能下,对应的风轮机输出转矩的变化特性以及随着风速的变化所对应的功率变化曲线。仿真结果表明所建立的风力机模型能较好的跟踪风速的变化,实现最大风能跟踪。By observing the wind speed data to get the Weibull wind speed distribution curve,the distribution of wind resources was found.According to the randomness of the wind speed change,wind speed model was established by Matlab.Afterwards simulation model of a variable pitch wind turbine rotor was set up.The output torque characteristics and the power conversion curve in the condition of maximum power point tracking was gained.The simulation results showed that the wind turbine model was able to track the change of wind speed and realize the maximum power point tracking.
