Fault Analysis of an AC Electric Railway System

초록

This paper presents the accurate modeling of an AC electric railway system. The system model is composed of the Scott-transformer, the auto-transformer, the running rails, the protection wires, the feeders, messenger wires and contact wires. After obtaining the models of the fundamental elements describing the AC electric railway system and its behavior, we compare hand calculations with the results from the PSCAD/EMTDC simulation to verify the proposed model for the fault study. As a practical usage of the proposed model, the results of fault simulations for the Incheon International Railway in Korea are reported
