This article utilizes wavelet analysis, a relatively new
mathematical tool, designed to develop an algorithm of
analysis for electrical transients in electric power
systems. Techniques, which are currently used, fall into
two main categories: time domain or the integral
transform domain. Both of the aforementioned categories
can be stressed when solving equations with a wide
spectrum or when a system of equations is subjected to a
nonstationary forcing function. One of the benefits of
wavelet analysis, however, is the ability to resolve
nonstationary nature signals easily. Based on the discrete
time domain approximation, the system components such
as resistor and inductor are modeled in discrete wavelet
domain for purpose of transient analysis. The method can
be implemented by any kind of orthogonal wavelet
transform. Computer simulations verified the
effectiveness of the proposed method. The proposed
algorithm can be implemented to calculate the shortcircuits
in electric power systems
