In order to obtain better power regulation performance during the startup of doubly-fed induction generator(DFIG),a sliding mode controller(SMC)is introduced based on the power regulation of DFIG side.The method is to add a dynamic sliding mode variable structure controller based on exponential reaching law to the reactive power regulation voltage section.Simulation results show that the addition of SMC controller,achieves about 1s reduction in start regula-tion time of active power and reactive power and improvement in stability performance of the system indicating the effec-tiveness,rationality,and practicability of the method.
