| Abstract: | Active power filter is a type of novel harmonic suppression device. When used in unbalanced three phase circuits, it can compensate harmonic and negative sequence currents simultaneously. For this puropse, the sum of harmonic and furdamental negative sequence currents should be detected precisely. A real time detecting method for harmonic and fundamental negative sequence currents in unbalanced three phase circuits was theoretically analyzed, the simulation and experiment were done. The results made it evident that harmonic and fundamental negative sequence currents could be detected precisely by using this method. |
