Abstract: The increased demands on transmission, absence of long term planning and need to provide open access to generating companies and customers have together created tendency towards less security and reduced quality of supply. Essentially, FACTS opens up new opportunities for controlling power and enhancing the usable capacity. The development of FACTS controllers has followed 2 distinctly different technical approaches, both resulting in a compressive group of controllers able to address targeted transmission problems. The first group employs reactive impedances or a tap-changing transformer with thyristor switches as controlled-elements; the second group uses self-commutated static converters as controlled voltage sources. The Static Synchronous Compensator (STATCOM), based on the voltage source inverter is a widely used FACTS device. This study deals with the basic simulation of STATCOM and demonstration of transient stability enhancement using STATCOM through MATLAB/ SIMULINK.
