摘　　要：对笼型异步电机与电力电子变换器结合构成发电系统进行了研究 ,说明了采用直接转矩控制策略可使这种发电系统具有很好的输出电压特性。文中介绍了异步发电机直接转矩控制的原理与实现方法 。This paper presents a configuration of electrical generation system that composed of a cage type induction generator(IG)and a power electronic converter, and researches its control technology.The research work indicates that if the instantaneous active power of IG is controlled by means of controlling its instantaneous electromagnetic torque,this IG generation system can have better dynamic performance than the other approaches.This paper deduces the basic mathematical formula of direct torque control (DTC) of induction generator based on space vectors and the IG mathematical model.The system will be improved on its dynamic performance further by using load torque forward feed control strategy.The implementation of this IG generation system is introduced.The simulation and experimental results are also presented.
