Voltage Sag Mitigation by using SVC

Abstract

This paper deals with modeling and simulation of SVC in IEEE 14 bus System with Induction Motor load for avoiding voltage sag. Single phase to ground fault is applied in predominant Induction motor load bus for voltage sag analysis. The effect of reactive power compensation to prevent sag has been analyzed with and without SVC. Simulations of the SVC were carried out by using Power System Computer Aided Design (PSCAD) software. Simulation results prove that the SVC is capable of mitigating voltage sag with proper reactive Power support.
