| 摘 要： | 针对并联型有源电力滤波器的直流侧电压控制特点,提出了一种对直流侧电压进行柔性控制的并联型有源电力滤波器控制策略。该策略中,在直流侧电压控制部分引入反馈低通滤波器,削弱直流侧固有谐波对输出电流控制的影响;在电流控制的输出部分通过增加直流侧电压前馈系数,抵制在变换桥中可能引入的直流侧电压谐波影响。仿真结果表明直流侧电压柔性控制策略能够降低APF系统补偿后的电源电流总谐波畸变率,从而改善并联型有源电力滤波器的谐波补偿性能。

| Abstract: | According to the characteristic of DC voltage control in shunt active power filter (APF) system,the Flexible DC voltage control strategy for APF was promoted.A low-pass filter could be embeded in the feedback channel of DC voltage,in order to weaken the its intrinsic hamonic impact on current control.A DC voltage feed forward coefficient could be introduced into the output part of current control chain,so as to shut off another pipeline of DC voltage hamonic influence on current control.Simulation results i... |
