Abstract

Quantitatively evaluating the harmonic responsibility of harmonic source at the point of common coupling (PCC) is an important task of power quality management. Considering the change of background harmonic and the fact that the current monitoring system can only provide the voltage and current statistical values, a method called partial linear regression method for accurately calculating harmonic responsibility under PQDIF is proposed. By means of measuring the information of PCC, the proposed method builds a more accurate partial linear regression model of calculation of the equivalent harmonic impedance, and then design two-stage method to calculate the unbiased estimation of the equivalent harmonic impedance and the background harmonic voltage, finally implement the accurate calculation of harmonic responsibility under PQDIF . Simulation results of IEEE 14-bus system show the effectiveness and accuracy of the proposed method.
