Power System Stability Enhancement Using FACTS Devices

Abstract

To utilize maximum cross section of installed power system conductors, the diversion of imaginary power should be must .With this; we can achieve maximum utilization of real power generated at the station. Generally preset passive inductive VAR generators may share conductor portion when low demand times. Active VAR generators are preferred to overcome this issue .Further control systems helps to determine the required VAR and type of VAR such that conduction period of switch varies according to the requirement of load which is very advantageous nature of active VAR generators. The simulink models of STATCOM and SVC are present in this paper. The results are analyzed accordingly in this paper.
