Abstract

This paper presents the fault analysis of Korean AC electric railway system. The AC electric railway system is modeled by PSCAD/EMTDC tool. This system model is composed of the Scott-transformer, the autotransformer, the running rails, the protection wires, the feeders, messenger wires and contact wires, etc. After obtaining the models of the fundamental elements describing Korean AC electric railway system, studies for the steady state and fault conditions are carried out. Simulation result and hand calculation for the fault analysis are compared with field data. Finally, we acquire the specific characteristic of Korean AC electric railway system. The proposed model would be a powerful tool for designing and planning Korean AC electric railway system.
