An Improved Method for Determining Contribution of Utility and Customer Harmonic Distortions In A Power Distribution System

چکیده
This paper presents an improved method for determining the share of harmonic distortion generated by utility and customer in a distribution system. The method is based on a Norton equivalent circuit to represent the whole system, modeling the customer side with RLC components by using measured voltage and current at the point of common coupling (PCC). The proposed method evaluates the contribution of harmonic voltage and current distortion, which may appear from utility and customer sides of the system. Several case studies have been made to verify the accuracy of the method in determining the share of utility and customer harmonic distortions. Results showed that the proposed method can accurately determine harmonic contributions of utility and customer sides for measurement made at the PCC.

A New Procedure for Determining Current Harmonic Contribution around an Operation Point at PCC Using Load Modelling Based on Crossed Frequency Admittance Matrix
Abstract:Today, one of the important issues of power quality (PQ) in power systems is the current harmonics. Increasing expansion of nonlinear loads at different parts of the electric network makes harmonic distortion flow through the network. This causes the network to have background voltage and current harmonic distortion and even affect on the PQ of linear load performance. Therefore, it is...
