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, damp low frequency oscillation, and improve transient stability. This paper 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 paper the STATCOM is connected to the 230 kV line for a typical two machine transmission system. The study demonstrates that STATCOM not only considerably improves transient stability but also compensates the reactive power in steady state.
