Abstract

The use of FACTS devices for reactive power compensation offers a lot of benefits. However, these devices affect the distance protection scheme used by the transmission line protection system. This paper examines the impact of the TCSC on the apparent impedance seen by distance relay on the transmission line of Nigeria 330kv transmission network. The system mathematical model was developed and simulated using MATLAB/SIMULINK. Analytical study based on voltages and currents symmetrical components for single phase to ground fault, to show the impact of TCSC on distance relay was investigated. The simulation result showed that the distance relay over-reach or under-reach when power flow was controlled in the system using TCSC.

Keywords
