Harmonic Identification by DQ Axis with Fourier Method for Active Power Filters
This paper proposes a new method of harmonic identification named DQ axis with Fourier (DQF) method.It lies on the basis of the DQ axis method enhanced by the sliding window Fourier analysis (SWFA).The SWFA component and the zero-sequence current considered inside the DQF method Exploration Sets account for its excellent results on harmonic elimina
