Abstract: In any power system, unexpected outages of lines or transformers occur due to faults or other disturbances. These events, referred to as contingencies, may cause significant overloading of transmission lines or transformers, which in turn may lead. Flexible AC Transmission System (FACTS) controllers provide a new facilities, both in steady state power flow control and dynamic stability control. Static VAR controllers control only one of three important parameters (voltage, impedance, phase angle) determining the power flow in the AC power system viz. the amplitude of voltage at selected terminals of transmission line .Overloading Power flow control, in an existing long transmission line, plays a vital role in Power System area. In this the Static Var Compensator (SVC) and Thyrister Controlled Series Capacitor (TSCS) based FACTS device for minimize the losses and power flow in long distance transmission line. The problem of determining the optimal SVC and TCSC parameters is formulated as an optimization problem and a N-R method based approach is applied to solve the Optimal Power Flow (OPF) problem. Simulations are done on IEEE 30 bus system for a few harmful contingencies.
