Improved Method for Detection and Classification of Transients and Waveform Distortions Using Sine Fitting Algorithms

Abstract. In this paper, a method for detection and classification of some power quality disturbances (namely transients and waveform distortions) is presented. The proposed method uses sine fitting algorithms for extraction of the event from the voltage signal and for its classification. The performance of the proposed method is demonstrated by examples of measured events. Key words Power quality detection and classification, transients, waveform distortions, sine fitting algorithms. 1
