摘　　要：有源电力滤波器(APF)被认为是抑制谐波最有效的设备之一,其补偿电流的检测和反馈控制环节是决定其工作特性的关键性环节,直接影响到APF的补偿精度和补偿速度.为提高补偿电流环节的精确性与快速性,以并联有源电力滤波器为研究对象,重点对其参考信号控制方式进行深入研究,指出传统的谐波参考信号控制方式的弊病,并在对APF工作机理深入研究的基础上提出一种不同于传统方式的新型控制信号生成方式——基波参考信号控制方式,最后通过仿真验证这种新型控制信号生成方式的有效性和先进性.Active power filter（APF） has been widely researched and developed in the recent years.The compensation current detection and feedback control link are a critical part to determine its operating characteristics,impacting the APF compensation accuracy and compensation speed directly.In order to improve the accuracy and rapidity of the compensation current aspects,shunt active power filer was studied in this paper,focusing on its reference signal generated approach.The shortcomings of traditional harmonic reference signal control method were pointed out and a new method to generate the control signal was put forward.Further,effectiveness and advancement of the new method to generate the control signal were proved by simulation.
