摘　　要：有源滤波器具有动态跟踪补偿、滤除任意次谐波特点,是治理谐波有效手段。但能否实时补偿谐波,是有源滤波装置的关键。现有的有源滤波器通常忽略本身的延迟,影响谐波补偿效果。文章在分析影响有源滤波器时延因素基础上,经过对现有时延补偿方法对比分析,提出对现有谐波检测算法改进方法。改进后的谐波检测算法通过仿真验证,证明该方法具有计算简单,可补偿因有源滤波器本身时延对电网谐波补偿的不良影响。The characteristics of active power filter with dynamic track compensation and remove any times harmonic. It is an effective method for harmonic control. But can compensate harmonic in real time, is the key to active power filter. First analysis of active power filter compensate the delay caused by the factors, and the improved detection algorithm to solve the time delay problem of harmonics in theory, and use Matllab simulation to test its feasibility.
