Abstract

The location of FACTS device with respect to the distance relay has a significant effect on the apparent impedance seen by the protective relay. 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 mid-point. 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.
