Abstract
In the paper, working principles of the direct power control for the active power filter based on virtual flux was introduced, and a new control scheme for the three-phase three-wire active power filter was proposed. In the scheme, virtual flux was used to oriente, and the use of the voltage sensor in the conventional voltage orientation was omitted. As to attain the frequency control , the driving pulse was produced by the space vector pulse modulation (SVPWM)link. At the same time, the fuzzy PI controller was applied to the voltage control link of the direct power control system, with robustness and fast dynamic response as the advantages. The simulation results verified that the direct power control system for the active power filter based on virtual flux designed in this paper was correct and effective.关键词
