| description | There are some advantages of harmonic detection method based on positive sequence fundamental extractor, such as simple structure, fast response and higher detection accuracy and so on. Total harmonic distortion of extracted fundamental current will be higher as system contains some low-order harmonics and its proportion coefficient is larger. Hence, a method eliminating gradually low-order harmonic which utilize the frequency-selection characteristic of positive sequence fundamental extractor was proposed, which can extract harmonic signal accurately and enhance filtering effect of APF. Simulation results show the effectiveness and feasibility of this method. |
