摘　　要：带有电流控制电压型逆变器的新型双绕组异步发电机不仅克服了传统异步发电机电压随负载变化的缺点,而且提高了系统的电磁兼容性。其控制系统由两个PI电压控制器和一个滞环电流控制器组成。为了对其电压控制性能和调节速度进行研究,本文建立了计及磁路饱和的双绕组异步发电机及其控制系统的数学模型。对负载、转速突然变化等动态过程中电压控制性能进行了仿真研究。结果表明,该系统具有较好的电压控制性能和响应速度。To overcome the drawback of voltage varying with the load for traditional selfexcited induction generator and improve the electromagnetic compatibility, a novel dual stator winding selfexcited induction generator with a current controlled voltage source inverter (CCVSI) is presented in this paper. The control scheme consists of two PI voltage controllers and one hysteresis current controller. In order to study the performance and speed of voltage control, the mathematical model of this type of generator and its control system considering the magnetic saturation is proposed. The simulation shows that good performance and speed of voltage control can be achieved by this scheme.
