摘　　要：针对永磁同步发电机(permanent magnet synchronous generator,PMSG),以额定风速以下风能最大捕获为目标,采用直接反馈线性化理论设计的风力发电控制系统,在电力系统计算机辅助设计和电磁暂态模拟程序软件(power system computer aided design and electric magnetic transient in DC system,PSCAD/EMTDC)仿真平台上建立PMSG风力发电机组模型并进行仿真分析,仿真结果表明,直接反馈线性化方法能够有效实现风力发电机组的最大风能捕获和整个系统的稳定运行,具有较强的鲁棒性。Taking maximum wind energy capture below rated wind speed as a target,this paper uses direct feedback linearization theory to design wind power generation control system based on permanent magnetic synchronous generator（PMSG）.On the simulation platform called power system computer aided design and electric magnetic transient in DC system（PSCAD/EMTDC）,it establishes PMSG wind power generation unit model and carries out simulation analysis.Results indicate that the method of direct feedback linearization could effectively realize maximum wind energy capture of wind power generation unit and stable operation of the whole system which has stronger robustness.
