Implementation of UPFC for Improvement of Power Stability

Abstract

Abstract:The FACTS device which is usually called Unified Power Flow Controller (UPFC) can give synchronous control of basic power system parameters like voltage, flow of active power, flow of the reactive power, the impedance and the phase angle. In this research work, simulation models for various multi machine systems are carried out, e.g. a hybrid power system, a power system with two synchronized hydro power stations etc., without UPFC &with UPFC presented at the load end of the power system, has been developed. Simulation models have been intergrated into MATLAB based Power System Toolbox (PST) for analysis of their voltage stability. The study of these models were for voltage, active power flow, and reactive power flow and phase angle, with and without UPFC. The results of the power system with UPFC and without UPFC are compared.
