FACTS, UPFC and Damping of Power System Oscillations


This paper investigates the effective control signals for damping of oscillations by using Unified Power Flow Controller (UPFC) in coordination with Power Oscillation Damping Controller (POD). Modified Phillips-Heffron Model of SMIB system with UPFC is considered for the analysis. POD is designed to achieve improved damping performance of the SMIB system by selecting effective control signal. Investigations reveal that coordinated tuning of UPFC and POD provide the robust dynamic performance. Eigen value analysis validate the performance of various damping controllers.
