摘要
为了解决普通异步发电机电压随转速或负载阻抗变化的问题,该文提出了一种新型定子双绕组自激异步发电机。其定子上布置有两套三相绕组,一套为功率绕组,直接给三相整流桥负载供电;另一套为控制绕组,接三相脉宽调制电压型逆变器励磁控制回路。通过调节逆变器输出的无功电流达到调节电压的目的。仿真和实验表明,该文提出的新型发电机是一种电压调节的有效手段。
The voltage of traditional induction generator varies with the rotor speed or the load impedance. In order to solve this problem, a novel stand-alone dual stator winding induction generator is proposed in this paper. There are two three-phase windings housed in the stator. One is the power winding which directly provides the power to the three-phase rectifier bridge load, the other is the control winding which is conrected to the excitation control circuit composing of a three-phase pulse width modulation voltage-source inverter. The voltage regulation can be achieved by controlling the reactive current of the inverter. The results of simulation and experiment show that this kind of novel generator is an effective way.
