摘　　要：以永磁直驱风力发电机组为研究对象,建立了包括风力机、传动部分、永磁直驱发电机、矢量控制策略、最大风能捕获策略的整体数学模型;应用Matlab/Simulink工具,以建立的数学模型为基础搭建了永磁直驱风力发电机组仿真模型,并以两次阶跃风速为例对所建模型并网后运行特性进行了仿真研究。实现了永磁直驱风力发电机组的最大风能捕获和功率解耦控制,仿真结果表明,永磁直驱风力发电机组具有良好的运行特性,同时验证了所建模型的正确性和有效性。This paper focuses on the permanent magnet direct-driven wind power generation system. An overall mathematical model comprising the wind turbine, drive system, permanent magnet synchronous generators, vector control tactics, and maximum power point tracking tactics, is established. With this mathematical model, a permanent magnet direct-driven wind power system simulation model based on Matlab/Simulink is set up. Simulation is conducted on step changing wind speed as an example to examine the operation characteristics of the model after it is integrated into the grid. The simulation realizes the maximum power point tracking and the decoupling control of power for permanent magnet directdriven wind power generation system. Results show that the system has satisfactory operation properties, and also validates correctness and effectiveness of the model established.
