Performance analysis of STATCOM in real time power system

Abstract

Power is a major concern that has generated interest in electrical utilities and consumers. To assure a reliable power system, all the buses are expected to maintain steady acceptable voltage before and after being subjected to any disturbance. Among the FACTs devices a static synchronous compensator,(STATCOM) is analyzed to provide a reliable and feasible solution. This paper presents a comprehensive analysis of STATCOM with a real time power system concerning the problem of variable loading and losses. A real time substation with 20 bus are analyzed with power flow analysis with and without STATCOM. Without the connection of STATCOM, a observable changes in the system voltage, line flows and losses results in a unexpected system behavior. This automatically influence the quality of grid and hence the customers are affected badly, indicating the need of power flow analysis and location of STATCOM on the system to improve the voltage profile. It is demonstrated that the described model works to an excellent level in bettering the substation performance.
