Excitation Control System for a Dual Stator-winding Induction Generator based on Hysteresis Control

设计了双绕组感应电机发电系统。在电机定子上设置了功率绕组和控制绕组,前者接负载,后者接励磁调节器,采用控制绕组电压定向矢量控制,使用滞环控制器触发驱动逆变桥,实现了对端电压良好的控制,也不会给电网系统带来无功负担。在变负载和转速情况下,对端电压动态和稳态性能进行实验分析证明,该系统动态响应速度快,稳态性能良好。

A dual stator-winding induction generator is designed.Power winding and control winding are set on the stator. The power winding is connected to the load and the control winding is connected to the excitation adjuster.The system adopts certain direction voltage vector control of the control winding,uses the hysteresis controller to drive the inverter bridge,terminal voltage is well controlled and does not bring reactive burden to the system.Under the conditions of varying load and rotating speed,the dynamic and static performances of the terminal voltage are analysed.The experimental resuits verified that the system has high dynamic response speed and predominant stability.
