摘要
Abstract
Firstly, the advantages and disadvantages of some harmonic detection methods applied in active power filter (APF) are introduced, and a new harmonic detection method based on instantaneous reactive power theory is put forward. In this method, fundamental voltage is detected by ip-iq method without phase lock loop at first, which is used to calculated in p -q method; then, in the final the fundamental active current, reactive current and harmonic current can be detected accurately. Based on the proposed algorithm, a model is built and simulated with matlab7.0/simulink. The results prove that the method is accurate and feasible.关键词
