Paper Title
Wavelet Based Novel Approach Of Voltage Events For Evaluating Reliable Power Quality

The paper develops an approach based on wavelet transform for the evaluation of harmonic contents of power system waveforms. The new algorithm can simultaneously identify all harmonics including integer, non-integer and sub harmonics. In the first step of the approach, the frequency spectrum of the waveform is decomposed into sub bands using discrete wavelet packet transform filter banks. In the second step continuous wavelet transform is applied to nonzero sub bands to evaluate the harmonic contents.
