摘　　要：针对永磁直驱风力发电机组建立了包括风力机、传动系统、永磁同步发电机、变流器各部分的数学模型;根据最大风能跟踪原理,提出了发电机侧和电网侧变流器的控制策略;在Matlab/Simulink仿真环境下建立了永磁直驱风电机组的仿真模型,对风速阶跃变化时机组运行情况进行了仿真。仿真结果验证了所提出控制策略的正确性和模型的合理性。A mathematical model of direct-drive permanent magnet wind power system was built,which includes wind turbine model,drive train model,permanent magnet synchronous generator model and converter model as well.According to the maximum wind tracking principle,control strategies of converters at generator and power grid sides were put forward.The simulation model of the wind power system was built in Matlab/Simulink software environment,and the case of wind speed stepping change was simulated.The simulation result verified the validity of the control stratesy and the feasibility of the model.
