This paper uses a FACTS device, UPFC for damping power oscillation in transmission systems as the power oscillations might increase risk of instability in the system and may also reduce power quality when the power system is being exposed to any disturbance. FACTS controllers permit newer approaches to system stabilization. In the proposed system, whenever power oscillations are detected due to any system disturbance the UPFC provides voltage support and improves the power system stability. The proposed system improves damping performance when compared with other methods. Harmonics is reduced in this proposed system. The quicker power oscillation damping using UPFC ensures smooth and reliable flow of the power through transmission line. This paper implements the control scheme and result is thus obtained for oscillations damping using Unified Power Flow Controller (UPFC) based on the computer simulations using the MATLAB software.
