Abstract

This paper presents an expert system that is able to classify different types of power quality (PQ) events. The expert system uses the voltage waveforms and distinguishes the different types of voltage dips and swells. Both Fourier and Wavelet analyses are applied for extracting distinct features of various types of events as well as for classifying the events.
