摘　　要：瞬时无功理论在三相有源电力滤波系统的谐波及无功电流检测中获得了广泛的应用。提出了使用移相构造法将瞬时无功理论应用于单相有源电力滤波系统谐波电流的检测。同时还介绍了将负载电流移相任意角度后构成两相电流在旋转坐标下进行电流谐波检测的方法。分别给出了其理论分析过程及应用在单相并联有源电力滤波系统中的仿真结果,通过仿真结果验证了结论。The instantaneous reactive power theory is widely used in the detections of harmonic and reactive current in three-phase active power filter. The method detecting harmonic current using instantaneous reactive power theory in single-phase active power filter by phase-shifting structured approach is presented. Also the harmonic current can be detected based on rotating reference frame method. The basic principle analysis and simulation results in single-phase parallel active power filter of these methods are presented. The simulation results verify the proposed methods.
