中文摘要:

根据三相电压型PWM整流器(三相VSR)工作原理,工程上常采用传统的电压电流双闭环控制系统,其存在启动时电压过冲、抗干扰能力弱、功率因数降低等问题。为此,本文提出了在电流内环引入有功电压前馈补偿,在电压外环引入负载电流前馈补偿的控制思想,优化了d-q坐标系下的电压电流双闭环控制策略，抑制了启动过程中的电压过冲问题，增强了系统的抗干扰能力，提高了功率因数。最后通过Matlab/ Simulink软件仿真分析,仿真结果验证了改进后的控制策略的可行性和有效性。

英文摘要:

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.
