中文摘要	在谐波电压较严重的电网中,对于以电源侧电流补偿为正弦波作为控制目标的有源电力滤波器(APF),需要考虑APF接入点处畸变电压的影响。本文分析了此类APF基于正弦波电源电压的控制方式的缺点,提出了一种具有接入点处谐波电压前馈控制的闭环控制新方法。这种控制方法不仅计算简单,便于工程实现,而且有效地提高了有源电力滤波器的动态响应速度。仿真结果表明,即使在电源电压严重畸变的情况下,APF也能取得很好的滤波效果。; The harmonic voltage becomes serious as more and more dynamic power sources and nonlinear loads are connected to the power grid. In some cases, an Active Power Filter (APF), which is paralleled to a point (called PCC: Point of Common Coupling) of the grid, is used to compensate the current of the power source side at PCC into a sinusoidal waveform. So it is necessary for the control strategy of APF to consider the influence of distorted PCC voltage. This paper points out the disadvantages of traditional control methods based on sinusoidal voltage and proposes a control method which adds a feed-forward loop of PCC voltage to a traditional closed control loop of APF. The algorithm of the method is easy to be implemented and the APF achieves satisfying compensation result even if the PCC voltage is badly distorted. The simulation confirms the performance of the method.
