Description :
Power quality may be defined as the measure analysis and improvement of the bus voltage usually load bus voltage to be pure sinusoid at rated magnitude and frequency. Due to increase use of non-linear and electronic based equipment’s the load bus voltage and current waveforms will not be a pure sinusoid in rated magnitude and frequency. This creates the disturbances in the system. In power system there are various kinds of power quality disturbances such as voltage sags (dips), swells, transients, flickers, harmonics etc. Among these voltage dips (sag) particularly troublesome, since sags in modern power system leads to tripping or misoperation of customer equipment and reduced life of the equipment. This paper presents the various power quality issues and various detection methods for determining the voltage sag and voltage swell. The prediction of voltage sag and swell in a power system is necessary for the analysis of supply reliability.
