| 摘 要： | 有源电力滤波器作为补偿电网谐波的装置,其性能很大程度上取决于能否快速精确地检测出谐波电流,而谐波检测算法中的低通滤波器的设计直接影响到检测结果的好坏.为提高谐波检测的精确性和实时性,通过对滤波器边带选择性的分析,提出了一种同时满足精确性和实时性的滤波器优化方法.理论分析、仿真和实验结果都证明了该方法的正确性和有效性.

| Abstract: | Fast and precise detection of the harmonic current is the key factor which determines the integrative filtering preferment of active power filter(APF),to compensate the harmonic current in power system.While the design of the low pass filter(LPF) is very important in the harmonic detecting.An optimum design based on band-edge selectivity was proposed.The results of simulation and experiment prove that the optimum design is correct and effective. |
