【摘要】 永磁同步发电机在风力发电中得到广泛应用,根据控制目标的不同,永磁同步发电机矢量控制方式分别有:零d轴电流控制、最大转矩电流比控制、单位功率因数控制和效率最优控制等。文章建立了永磁同步发电机的数学模型,介绍了几种不同目标下的矢量控制策略,并分析了每种控制策略的优缺点,对几种控制策略进行了对比。更多还原

【Abstract】 Permanent Synchronous Generator(PMSG) is widely used in wind power generation system.Considering different control strategy,PMSG vector control strategies can be classified as zero d-axis control,maximum torque per ampere control,unity power factor control and minimum loss control.The PMSG model is set up in this paper.Different control strategies are introduced,and the advantages and disadvantages of each control strategies are analyzed and compared.更多还原
