Abstract

This paper presents application of continuous wavelet transform to identify power system transients and disturbances. A mother wavelet basis function (Littlewood-Paley (L-P)) with dyadic nonoverlapping frequency bands has been used. A few power signals with power quality (PQ) disturbances have been analyzed to show the effectiveness of the proposed technique. The purpose of the paper is to highlight an alternative way of PQ signal analysis, which enables to identify the duration of disturbance accurately. Classification of various power quality disturbances is also possible through this timefrequency based wavelet analysis.
