Abstract

The paper presents a method of analysis of non-stationary nonsinusoidal modes of electric power systems (EPS) based on the
packet wavelet transform. Wavelet transform (WT) in contrast to the Short Time Fourier transform allows analyzing of higher harmonics in three-dimensional plane (amplitude, frequency, time). Absences of necessity to select window width when implementing WT avoids the negative effect of spectrum leakage. The use of WT calculation of higher harmonics will improve the accuracy of the assessment additional losses in EPS and develop events to improve energy efficiency of power systems.
