L.S. Safavian, Witold Kinsner, H. M. Turanli · 2006
This paper presents a study of wavelet analysis of transients in power systems. Short-term and non-stationary nature of transients necessitates the use of advanced signal processing techniques in order to detect, characterize and classify them. The paper examines the fundamental properties of a number of mother wavelets, and provides guidelines for the selection of suitable wavelets for the purpose of characterization and extraction of features of transients in power systems. As an indispensable part of such a study, the paper also presents the results of wavelet analysis of typical types of transients obtained using simulation
