| Abstract: | In response to the application of active power filter,an improved ip-iq algorithm for harmonic and fundamental reactive current detection based on instantaneous reactive power theory has been presented in this paper.The improved method can decrease the complex mathematical transformation and can be directly used in harmonic currents and fundamental current detection for three-phase three-wire,three-phase four-wire and single-phase distribution systems.A new dual-filter method of series filter technology is ... |
