Abstract :
The wavelet transform is introduced as
a method for analyzing electromagnetic transients associated
with power system faults and switching. This
method, like the Fourier transform, provides information
related to the frequency composition of a waveform, but
it is more appropriate than the familiar Fourier methods
for the non-periodic, wide-band signals associated with
electromagnetic transients. It appears that the frequency
domain data produced by the wavelet transform may be
useful for analyzing the sources of transients through
manual ,or. automated feature detection schemes. The
basic principles oi wavelet analysis are set forth, and examples
showing the application of the wavelet transform
to actual power system transients are presented.
