| 摘 要： | 永磁同步发电机目前在各种驱动系统中的应用越来越多,采用单位功率因数控制方法对PMSG进行控制,可以降低变流器的功率等级,但是常规的UPF控制实现比较复杂.采用一种近似UPF控制方法,在电机参数满足一定假设条件的情况下,对PMSG的UPF控制方法进行简化,并将这种方法应用于永磁直驱风电实验系统中.仿真和实验结果证实了所采用的PMSG近似UPF控制策略的有效性.表明所提出的近似UPF控制策略可以基本实现永磁直驱风电系统PMSG的单位功率因数控制,获得良好的控制效果.

| Abstract: | The application of permanent magnet synchronous generator (PMSG) in adjustable-speed drive system is more and more,the converter power rating can be reduced by using unity power factor (UPF) control strategy,however the realization of conventional UPF control is much complicated. A kind of approximate UPF control method was adopted to simplify the UPF control of PMSG,when the motor parameters meet some certain assumption,and the proposed method was applied in direct-driven wind energy conversion system (WEC... |
