Determining IEEE 519 Compliance of a Customer in a Power System

Nonlinear loads inject harmonics in a power distribution network. The interaction of the nonlinear load harmonics with the network impedances creates voltage distortions at the point of common coupling (PCC) which in turn affects other loads connected to the same PCC. This paper presents a neural network based technique to establish determine the true current harmonic distortion of a customer in the presence of distorted voltage. The proposed method is applied at the primary metering point of a customer in a distribution network and the results are used to establish compliance with IEEE 519.
