摘要：This study aims to determine the effect of UPFC as a Flexible AC Transmission System (FACTS) tool to improve dynamic stability. FACTS is a power electronic device used for various controls on power transmission systems. Power Flow Control, Oscillation Control System can be done by FACTS device. FACTS devices using the Unified Power Flow Controller (UPFC) are modelled to see the performance of dynamic oscillations through software-assisted simulations. Dynamic oscillation occurs due to a temporary disturbance or Short Circuit, causing instability. UPFC devices which are installed on the transmission line. Effect of UPFC to damp oscillation of power system with a model. The injection model is modelled by the active and reactive power supply equation of the injected UPFC to the transmission line. A dynamic oscillation repair is performed by regulating the shunt bus voltage of the reference value and which maintains the dc link on the capacitor voltage. Voltage, The magnitude in the shunt bus, depends on the injected reactive power, where the dc is connected to the capacitor on the UPFC device. The injection model is applied to the simulated effect of UPFC device, showing the simulated effect of UPFC mounting can improve the oscillation caused by disturbances in the power system. Speed Change Oscillations for the generator 1 dan Generator 2, the system without UPFC oscillates for Generator 1, with Over-shoot 6.5x10-1 while using UPFC Over-shoot of 4x10-4. UPFC can reduce the speed change in Generator 1 in about 7.5 seconds; the system returns the equilibrium position (Steady-State).
