摘要(Abstract)：

以Matlab/Simulink为平台搭建永磁同步风力发电系统,通过对基于移动指数平均算法(EMA)的功率误差控制器对永磁风电系统功率环的波形影响进行分析,发现可以以一个函数实现EMA控制算法对功率误差的作用。在此基础上提出以一个新的函数代替EMA算法中的模糊逻辑控制器为基础的改进型EMA算法,并将其作为永磁风力发电系统的功率误差控制器。经过Simulink仿真平台分析波形,得出改进型EMA算法具有对永磁风力发电系统功率优化的功能;且通过对比传统EMA算法和改进后的移动指数平均算法的仿真波形与数据及其算法的数学结构,可知所用的新函数具有代替模糊逻辑控制器实现移动指数平均算法在PMSG功率控制上所具有的优化功能。
