Performance of Distance Relays in Presence of IPFC

Abstract

In this paper, the analytical and simulation results of the application of distance relay for the protection of transmission line incorporating Inter-line Power Flow Controller (IPFC) are presented. Firstly a detailed model of the IPFC and its control is proposed and then it is integrated into the 8-bus transmission system for the purposes of accurately simulating the fault transients. The simulation results show the impact of different operational mode of IPFC on the performance of a distance protection relays.
