摘　　要：三相三线并联有源电力滤波器能够实时的补偿谐波电流和无功电流。目前,并联有源电力滤波器的补偿原理大多是补偿电流跟踪检测出的参考谐波电流。在分析以往的补偿原理之后,提出了把检测出的谐波功率作为参考功率信号,然后,采用直接功率控制方法,设计有源电力滤波器的控制器,使滤波器的输出的谐波功率跟踪参考功率,从而达到消除谐波的目的。仿真试验结果表明,采用这种控制策略设计出的有源电力滤波器具有良好的谐波补偿效果。Three-phase three-line shunt Active Power Filter （APF） can be used to restrain harmonic currents and compensate reactive power current on-line. At present, most of the compensation principles of APF are that the compensation currents track the detected reference harmonic currents. After the analysis of the previous compensation principles, a novel control method is proposed in this paper that harmonic power is detected to be the reference compensation power firstly. Then, adopting Direct Power Control （DPC） method, an APF controller is designed to make compensation power track the reference compensation power, so as to achieve the purpose of eliminating harmonics. At the end, simulation results indicate that the APF based on DPC shows perfect harmonic compensation performances.
