Abstract: The aim of this paper is to present modeling of power quality disturbances based on parametric equations. Parametric equations are considered for transients, short-duration voltage variations, harmonics, voltage sag with harmonics, voltage swell with harmonics, voltage fluctuations, and voltage flicker. The short-duration voltage variations include voltage interruption, voltage sag and voltage swell for a short period. The classification of power quality disturbances is based upon the magnitude of the disturbance and duration of occurrence. The power quality disturbances results in reduction of stability of the power system. So there is a necessity for proper evaluation of power quality disturbances. Power quality solutions along with required monitoring equipment are chosen by evaluating the type of power quality disturbances. The effect of power quality disturbances can be reduced only after their identification by providing an accurate analysis. The modeling of power quality disturbances performs an important role in power quality evaluation. Any of the signal processing techniques can be applied for extracting useful information from the signals. Waveforms for transients, interruption, sag, swell, harmonics, voltage sag with harmonics, voltage swell with harmonics, voltage fluctuations, and voltage flicker are generated using a suitable code based on parametric equations in MATLAB environment.
