三相VSR的一种改进型前馈补偿控制策略研究
The Study of a improved feedforward compensation control strategy for Three-Phase VSR
According to the working principle of three-phase voltage source PWM rectifier(VSR), Projects often use traditional voltage current double closed loop control strategy, which has the problem of the voltage overshoot,weak anti-interference ability and low power factor.To this end, the paper put forward a modified controy strategy, whitch an active voltage feed-forward compensation introduced in the current inner loop, a load current feed-forward compensation introduced in voltage outer loop.The modified controy strategy suppressed the voltage overshoot, improved the anti-interference ability of the system, and improved the power factor. Finally, by Matlab/Simulink software, the simulation results verifyed the feasibility and effectiveness of the modified control strategy.
