This paper deals about one of the FACTS devices which is called UPFC (Unified Power Flow Controller). It is used to control reactive (KVAR) and active power (KW) by means of adjusting bus voltage at the located line. UPFC can improve the quality of power within their limits on the targeted line. That’s why this device has the different way of controlling the power flow and voltage stability. Without UPFC, it is impossible to control voltage, reactive and active power. In this thesis, we can also analyze by attaching fuzzy logic controller to this system. The simulation models are made in MATLAB software. Under simulation we get results for with and without using UPFC and then we compare these results in the form of active and reactive power in the required line. By comparing these results, we decide that UPFC is an ideal controller.
