Abstract: This paper analyzes the performance of traction system under various faults. The faults are generated in three phase grid and between the substations. To understand the effects and severity of faults the whole traction system is embedded and developed using MATLAB/Simulink model. Voltage sag and harmonic issues are source of concern when such type of fault occurs in traction system. FC-TCR (SVC) is used as a compensator which not only improves the voltage profile but also mitigates harmonics.
