Influence of Unified Power Flow Controller on Flexible Alternating Current Transmission System Devices in 500 kV Transmission Line

Power system maintenance and reliability has become an important aspect of research. In this paper the performance of unified power flow controller to control the power flow on the transmission line has been discussed. The voltage source model was used to study the UPFC's behavior in regulating active power, reactive power and voltage curves. Summarized the different results to see the benefits of UPFC in the power system by installing the Power system modeling in MATLAB and installation of UPFC in transmission link.
