Islanding and Non-Islanding Detection for Grid Connected Distribution System

Abstract:

In this paper, wavelet transform based approach is proposed for islanding detection in a distribution system. The negative sequence voltage and negative sequence current obtained due to disturbances are measured at the point of common coupling (PCC) and given to the wavelet processing module to extract features like standard deviation and energy content. The negative sequence voltage and current components are decomposed under various levels to filter out lower frequency components. From the obtained features suitable threshold value is fixed for classifying the islanding and non-islanding events.
