Abstract

This study presents a method for determining the contribution of harmonic distortions generated by utility and customer at the Point of Common Coupling (PCC) in power distribution systems. The method is known as the RLC method as the customer load is modeled with RLC components using measured voltage and current at the PCC and the system is represented by a Norton equivalent circuit. The contributions of harmonic voltage and current distortions from utility and customer sides of the system are derived by estimating the customer impedance and then calculating the harmonic currents at customer and utility sides. Several case studies have been made to verify the accuracy of the proposed RLC method in determining the contribution of utility and customer harmonic distortions by making a comparison with the IEEE1459-2000 standard based method. Results showed that the proposed RLC method can accurately determine the harmonic contributions of utility and customer for measurements made at the PCC.
