摘　　要：有源电力滤波器是一种消除电力系统谐波污染的重要装置,随着电力电子技术的发展,它的使用也越来越广泛。针对有源电力滤波器的特点,基于瞬时无功功率理论,提出一种对于任意指定次数的谐波电流的检测算法。该算法能够克服数字式控制器延迟时间对于谐波补偿的影响,可实现谐波的实时补偿。Active Power Filter is an important device to eliminate the pollution of harmonics and with the development of power electronics, this device becomes more popular. A new algorithm for random harmonic current detection of active power filter based on instantaneous reactive power theory is presented in this paper. This algorithm can overcome the infection of the digital controller's delay time to harmonic compensation and realize the real time compensation. Analyses and simulation prove the correctness of the algorithm.
