摘　　要：分析永磁直驱风电机组的优点并建立各部分的数学模型,根据变流器的数学模型,提出变流器机侧和网侧的控制策略,能够实现风电机组有功功率和无功功率的独立控制,获得较好的电能质量;利用仿真软件MATLAB/SIMULINK建立永磁直驱风电机组的模型,仿真了机组在风速阶跃变化时的运行时情况,仿真结果验证了模型的正确性。Analysis of the advantages of direct-drive permanent magnet wind turbine and build a mathematical model of every part of turbine, based on the mathematical model of the converter, the control strategy at generate side and power grid sides of the converter is put forward, the active and reactive power of the wind turbine can independent control, and which is able to obtain better power quality; using the simulation software MATLAB/SIMULINK to build direct-drive per- manent magnet wind turbine model, and simulating runtime conditions when the wind speed is stepping change. The simulation results testify the validity of the model.
