This can be analysed by means of comparing the actual measured impedance at the relaying point and the ideal tripping characteristics of the relay. Two case locations of the Thyristor Controlled Series Capacitor (TCSC) on the Ikeja West to Benin transmission line in the Nigeria power system were considered with respect to the concerned distance relay, i.e. at near end and midpoint. The effects of installation of TCSC at different locations on the transmission line distance relay were investigated under different fault conditions by the simulation model of the TCSC, simulated in the Nigeria power system using MATLAB/ Simulink software. The simulation results were discussed and used to compare the impact of TCSC located at various points on the transmission line with respect to a fault.

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.
