摘要
为了在DFIG系统启动时获得更好的功率调节性能,在DFIG机侧引入滑模控制器(SMC).在无功功率调节电压环节加入基于指数趋近律的动态滑模变结构控制器,仿真结果显示在加入 SMC控制器后,有功功率及无功功率的启动调节时间约缩短了 1s,系统稳定性也有所提升,表明该方法有效、合理,适用于工程.
Abstract
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.
