Abstract: FACTS devices have different applications in power system related to operation and control of power system, such as scheduling power flow; damping the power oscillations and enhancing transient stability. It is proved that the FACTS devices are very much effective in power flow control and damping out the swing of the system during fault. Among all FACTS devices the UPFC most popular controller due to its wide area control over power both active and reactive, it also gives the system to be used for its maximum thermal limit. Oscillations in power system are major problem related to power system. This oscillations make the system unstable and system may collapse. To avoid this problem development of FACTS device is very much popular form last few years. Unified Power Flow Controller is one of the facts device use to damp the oscillations and system stability enhancement. The UPFC is the most flexible FACTS equipments. UPFC perform the functions of the static synchronous compensator (STATCOM), thyristor switched capacitor (TSC) , thyristor controlled reactor (TCR), and the phase angle regulator offering the flexibility for the static and dynamic operation of the power network. It controls all the electrical variables of the transmission network.
