摘要
利用电流型PWM变流器实现了绕线转子感应电动机串级调速,通过对变流器矢量控制方案的研究,实现了在调速的同时转子能量的回馈,同时利用转子回馈能量对电动机的功率因数进行补偿,使功率因数接近为1.0。调速系统具有可靠性高、寿命长、谐波含量小、成本低等优点。实验证明了方案的可行性。
This paper has proposed a kind of novel adjusting speed method about wired rotor induction motor with current-type PWM rectifier, the rotor energy is fed back while adjusting speed. The compensation of the reactive power by the energy from rotor can be done very easily, high efficiency, high liability, long life,lower price and unity power factor has been achieved. The experimental tests show excellent performance in both steady state and transient conditions.
