Transient Stability Improvement of Interconnected System Using STATCOM Controller

Abstract

The static synchronous compensator (STATCOM) is one type of FACTS devices which resembles in many respects a rotating synchronous condenser used for voltage control and reactive power compensation. The STATCOM can increase transmission capacity, damping low frequency oscillation, and improving transient stability. This project presents a control block diagram of STATCOM for the transient stability improvement. The SIMULINK/MATLAB software package is used for simulation of test system. In this project the STATCOM is connected to the 500kVline for atypical two machine transmission system. The study demonstrates that STATCOM can improve transient stability and also compensate the reactive power in power system networks.
