Abstract

This paper proposes a Wavelet-based method for signal analysis. By generating the frequency and voltage responses of the different generators at a particular fix point of bus are studied. Wavelet transform (WT) based multiresolution analysis and its properties are studied for frequency and voltage responses of power system signals in smart grid. Considering wavelet energy of wavelet coefficients (WCs) as a criterion, order 2 Daubechies wavelet and scale 5 as the excellent wavelet function and optimal decomposition scale. The voltage and frequency responses are obtained in IEEE New England 39- bus system.
