Selective harmonic current mitigation with a Shunt Active Power Filter

This paper proposes a Shunt Active Power Filter (SAPF) for harmonic mitigation based a selective harmonic current mitigation (SHCM) method. The proposed SHCM method improves the filtering efficiency and solves many issues existing in highly contaminated loads. The Fast Fourier Transform (FFT) is applied to a specific harmonic current detection of a three-phase circuit. A simulation study of a three-phase compensated system is carried out using Matlab/Simulink^® to validate the proposed method.
