Abstract

An Unified Power Flow Controller (UPFC) is a typical Flexible AC Transmission System (FACTS) device playing a vital role as a stability aid for large transient disturbances in an interconnected power system. This paper deals with the design of Feedback Linearising Controller (FBLC) for UPFC. The 3-phase fault is created on the SMIB system and the results are simulated. The results proved the supremacy of the Power System Stabilizer (PSS) equipped with FBLC over the PSS equipped with Proportional Integral(PI) controller.
