摘要：The proliferation of nonlinear household appliances has resulted in significant harmonic distortion in low voltage distribution networks. Harmonic modeling is the prerequisite to evaluate the harmonic pollution caused by nonlinear household appliances. This paper presents a harmonic coupled admittance matrix (HCAM) model of the nonlinear household appliance based on the measured voltage and current data. Compared to constant current source model, the HCAM model can illustrate the coupling relationship between harmonic voltages and harmonic currents, which contributes to a high harmonic modeling accuracy. The parameters of HCAM model are estimated by using widely linear complex partial least square (WL-CPLS) method which can effectively overcome the collinearity problem among data. Experiments have been done for multiple different household appliances, the results of which demonstrate the validity and accuracy of the proposed model. © 2019 IEEE.
