The developing countries use thyritor, GTO, IGBT, MOSFET, and many other electronic device. These are use for switching devices because its initial cost is low. The switching device are mechanical and then operating signal are sent to circuit where final control action take place, these are the slow process. Another problem are also associated with mechanical switch that it cannot control frequently[2]. To reduced this problem use in FACTS technology. It is developed in 1990. It can also use series and shunt condition. It is power electronic based and static device such as Thyristors, Gate turn offs(GTO), Insulated gate bipolar transistors(IGBT), Insulated Gate Commutated thyristors (IGCT),they can be controlled very fast as well as different control algorithms adapted to various situations[5]. The FACTS technology is use for controlling the both types of powers and enhancing the USAble capacity of present transmission systems[6]. It has increase line capacity .The ability of FACTS controllers to adjust the power system electrical parameters including series and shunt impedances, current, voltage, phase angle, and the damping oscillations etc. The FACTS devices has various power electronics devices [1]
