The quality of power supplied is affected by various internal and external factors of the power system. The presence of harmonics, voltage and frequency variations deteriorate the performance of the system. In this project the frequently occurring power quality problem- voltage variation is discussed. The voltage sag/dip is the most frequently occurring problem. To overcome the problem related to power quality many power devices are introduced. A number of power quality solutions are provided by these power devices. At present, a wide range of very flexible controllers, which capitalize on newly available power electronics components, are emerging for power applications. Among these, the static compensator is use in the present work. The fast response of static compensator makes it the efficient solution for improving power quality in distribution system. STATCOM can use with different types of controllers. The device consider in this work is Static Synchronous Compensator (STATCOM) to improve the power quality under different abnormal conditions like single line to ground fault, double line to ground fault in distribution networks with static linear and static non-linear loads.
