Identification of Harmonic Injection and Distortion Power at Customer Location

Abstract

This paper focuses on identifying harmonic injection by non-linear load at customer location. Presently, customer harmonic contribution cannot be accurately measured leading to penalizing customers not causing harmonic pollution. Hence this matter is of utmost importance since more non-linear loads penetrate into system. These harmonic currents causes voltage distortion at PCC affecting the linear loads. As a result distortion powers flows in the system creating additional power loss. A new index is defined for accurately identifying the harmonic injection of individual customer and distortion power is calculated as per IEEE standard 1459-2010. Simulation results validate the proposed method. Further development can lead to a tariff regime where only actual harmonic polluters be penalized.
