摘要：ABSTRACT: This paper presents transient stability and power flow models of static synchronous compensator (STATCOM) and current Sourced Inverter (CSI) based Flexible AC Transmission System (FACTS) Controllers. A model of the static synchronous compensator (STATCOM), the application of the static synchronous compensator (STATCOM) in improving transient stability in power systems.MATLAB/SIMULINK is used to simulate the system under study. 'This paper presents a control block diagram of STATCOM for the transient stability improvement. The MATLAB/SIMULINK software package is used for simulation of test system. In this paper the STATCOM is connected to the 230KV line for a typical two machine transmission system. The study demonstrates that STATCOM not only considerably improves transient stability in steady stat. Due to its simplicity, robustness and ease implementation, proportional integral derivative (PID) controller along with auxiliary feedback signals are used to control the inverter firing angle and hence control the reactive power exchange between the AC system and the STATCOM.
