JEE_V7_N1_RP6 Rammurthy B.M. K.V. Satheesh Babu Journal on Electrical Engineering 2230 – 7176 7 1 41 48 Hybrid Power Flow Controller (HPFC), Flexible AC Transmission Line (FACTS), Transient Stability This paper is based on the practical contingency condition of a transmission line, over which a study using HPFC is done without sacrificing the available generation capacity. The Hybrid Power Flow Controller (HPFC) is the most versatile and complex power electronic equipment that has emerged for the control and optimization of power flow in electrical power transmission system. Installing the HPFC makes it possible to control an amount of real and reactive power flow through the line. This paper presents the control of power flow through multiple overloaded/under loaded lines under study. Simulation is carried out using MATLAB software to overcome the contingency condition by using HPFC. July - September 2013 Copyright © 2013 i-manager publications.
