Detecting Method for Harmonic and Fundamental Negative Sequence and Zero Sequence Currents in Unbalanced Three-Phase Four-Wire Circuits

Article Preview

Abstract:

Shunt Active Power Filter (SAPF) is a new device for compensating harmonic currents in power system [1]. For unbalanced three-phase four-wire circuits, it need detect the total of harmonic and fundamental negative sequence and zero sequence currents at the same time. Base on traditional method of ip-iq, a detecting method which is suitable for unbalanced three-phase four-wire is proposed and analyzed by mathematical reasoning. At last, correctness of the result is verified by simulation.
