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