摘　　要：采用等效电路的方法,建立了包括风力机、发电机侧PWM整流器在内的直驱式永磁风力发电机的机侧数学模型,应用坐标变换将三相静止坐标系上的数学模型转化成了d-q旋转坐标系上的数学模型。采用电流内环和电压外环的双闭环控制策略,并利用Matlab/Simulink软件平台搭建了系统的仿真模型并进行仿真。仿真结果证明了机侧功率因数控制的可行性与有效性。Using the method of equivalent circuit,the directly-driven permanent magnet wind generator＇s mathematical model is built,which includes the wind turbine model and the generator-side PWM rectifier model.Applying of the coordinate transformation,three-phase stationary coordinate system mathematical model is transformed into the mathematical model on d-q rotating coordinate system,and the double-loop control strategy of current inner loop and outer voltage loop is applied.Then,Matlab/Simulink software platform is used to establish the simulation model of the entire system and start to simulate.The simulation results show the feasibility and effectiveness of power factor of generator-side＇s control.
