Abstract

In this paper, the impact of Unified Power Flow Controller (UPFC) and series capacitor on transmission system reliability is examined. UPFC is used for natural sharing of power where as series compensator is used for reducing the effect of inductance. Addition of capacitance in series with the transmission line modifies the reactance of line. UPFC & series compensator are connected in series to each other to utilize more maximum power. Reliability analysis of the entire transmission system is being carried out by using load indices like Loss of Load Expectation (LOLE) & Loss of Energy Expectation (LOEE). A new noval approach of both components has been presented to show more improvement in the system reliability. A comparison has been carried out between the FACTS controllers (UPFC & TCSC (Thyristor Controlled Series Capacitor)), the results show a major improvement in the system reliability when using UPFC & series compensator.
