Research on the responsibility partition of harmonic pollution and harmonic impedance based on the total least-squares regression method

摘要

This paper introduces a method for the responsibility partition of harmonic pollution of harmonic source, which is based on the total least-squares regression. Through the NORTON circuit transformation to construct harmonic impedance of binary linear regression equation in the system side and customer side. Utilizing the signals of harmonic current and harmonic voltage measured at PCC(Point of Common Coupling), the system side and customer side harmonic impedance are worked out through the total least-squares regression, then the harmonic power of system side and customer side are calculate. The simulation analysis indicate that the proposed method is valid and feasible.
