ABSTRACT A simulation model of static synchronous compensator (STATCOM) has been constructed on Matlab/Simulink software to examine its capability for voltage sag mitigation due to starting high power induction motor. In this paper, the main structure of Simulink (STATCOM) model is described briefly. Its capability to compensate reactive power to the system when the voltage sag occurs was described. A phase control thyristor (SCR) based voltage source inverter (VSI) is employed for this application. The influences of the initial operation point and DC capacitance are considered. The behavior of this system during voltage sag caused by starting of motor load has been examined. Simulation result shows the fast response and the STATCOM capability for mitigate voltage sag.
