摘要
提出了一种简易的双馈电机的控制方法,通过检测转子侧的电流,控制转子电压与转子电流同相或反相.双馈调速时,如果转子电压矢量与转子矢量始终保持同相(对应于超同步)或反相(对应于亚同步),就能保证转子侧的功率因数为1,可以减小转子侧的变频率容量.本文对这一方案进行了分析、进行了仿真和实验.
A simple vector control method for doubly-fed machine is presented in this paper. It can be achieved by detecting the rotor current so as to keep the direction between the voltage and current inphase or outphase, and so, the power factor could approach 1.0, which can reduce the capacity of the inverter. Also presented in this paper are the analysis, simulation results and experiment on the method.
