Voltage Collapse Avoidance by using STATCOM

Abstract

This paper deals with modelling and simulation of STATCOM in IEEE 14 bus System with Induction Motor load for avoiding voltage collapse. Three Phases to ground fault is applied in predominant Induction motor load bus for voltage collapse analysis. The effect of Critical Fault Clearing Time [CFCT] of the system due to facing the fault, to prevent permanent voltage collapse has been analyzed with and without STATCOM. Simulations of the STATCOM were carried out by using Power System Computer Aided Design (PSCAD) software. Simulation results prove that the STATCOM is capable of mitigating voltage collapse with minimum clearing Time.
