三相 VSR 的一种改进型前馈补偿控制策略研究
Study on an improved feed-forward compensation control strategy for three-phase VSR
摘要
Abstract
According to the working principle of three-phase voltage source PWM rectifier (VSR), the projects are of-tenused in the traditional voltage current double closed loop control strategy , which causes problems such as voltage overshoot , weak anti-interference ability and low power factor .The paper puts forward a modified control strategy , in which an active voltage feed-forward compensationcan be introduced into the current inner-loop, and a load current feed-forward compensation can be introduced into voltage outer-loop.This modified double closed-loop control strategy is able to decrease the voltage overshoot , improve the anti-interference ability of the system , and improve the power factor.Finally, the simulation of the control system was built with Matlab/Simulink, the simulation results have veri-fied the feasibility and effectiveness of the modified control strategy .关键词
