Steady State Voltage Vulnerability and Stability Limit Analysis of Bangladesh Power System Using STATCOM as a Shunt Compensator

Abstract

Highest consistency of transmission line is very noteworthy due to enhancement of demand. Voltage stability and steady state limit are matter of great concentration as it plays an imperative function in Bangladesh Power System (BPS). In this paper we have used Modal analysis technique to scrutinize steady state voltage vulnerability and Continuation Power Flow (CPF) technique to assess steady state voltage stability limit in East-West Interconnector System (EWIS) of BPS using NEPLAN software. Inadequate reactive power in the power system causes voltage collapse which is mainly a local problem. This can be overcome by adding shunt compensative device like Static Synchronous Compensator (STATCOM). Inclusion of shunt FACTS (Flexible AC Transmission System) increases the stability and loading factor. The comparative result with and without STATCOM is also shown in BPS.
