Unified Power Flow Controller (UPFC) is the greatest multipurpose Flexible AC Transmission System (FACTS) scheme due to its capacity to control real and reactive power on transmission lines and adjusting the voltage of the bus to which it is attached. It is compulsory to analyze its effect of UPFC on power system network when the fault occurs in the power system and therefore whole system goes to severe transients. By using PSS and AVR we can simply stabilize the system. FACTS devices like TCSC, SVC, STATCOM, and UPFC are important device to suppress the power system oscillations under faults occurrence and enhance the damping of the system. The power electronic devicetermed as UPFC which efficiently control the active and reactive power. To carry out small signal stability analysis with the proposed method, a SMIB linear model of Philip-Heffron model, a recognized model for synchronous generator has been employed. Recent past has witnessed the advancements of Power System Stabilizers (PSS) and their variants for enhancing the stability of power system. But the added advantages of FACTS based design outperformed PSS in terms of performance and implementation perspective. The simulation results show that PSS and FL based PSS improves the stability of the SMIB scheme and power system fluctuations are successfully damped out. The unified power flow controller (UPFC) has various applications together with loop flow control, power flow control load sharing among parallel passages, modification of system oscillations, and voltage (reactive power) regulation and development of transient stability. In this thesis, MATLAB simulation package is employed to simulate the UPFC model.
