摘要
针对有源电力滤波器(APF)投入电网启动时的冲击电流、电压问题,在已有的直流侧电容电压控制方法基础上,提出一种改进型多比例积分(PI)控制器的控制策略进行软启动,使电容电压从零到电容电压期望值的上升率、超调量得到有效控制。在Matlab/Simulink中进行仿真验证,并在60 kVA实验样机中进行实验,结果证明了该方法的正确性和可行性。
For the issue of over current and over voltage which occurs while the active power filter （APF） is started into the grid,an improved multi proportional integral（PI） control strategy in the method for soft-start is presented based on the control method of the existing DC capacitor voltage, making capacitor voltage be controlled from zero to capac- itor voltage expectation effectively in rate of its rise and the overshoot.The results by Matlab/Simulink and a 60 kVA experiment prototype demonstrate the correctness and the validity of the theory.
