Abstract: In this research paper stability of power systems are analyzed by using a STATCOM. The STATCOM is a shunt connected facts devices. Mostly static compensator enhances the power system stability under three phase faults. The bus voltages are controlled using shunt type facts device. The control strategy is implemented by static synchronous compensator devices and it is found that system performance is enhanced under three phase faults. Due to three phase fault the problems arises in generator voltage, generator current, Infinite bus voltage, Infinite bus current and generator load angle of a power system are investigated in detail and resolved by designing and testing a test system using MATLAB/SIMULINK
