Modelling of AC Electric Railway System using PSCAD/EMTDC

This paper introduces a complete model of the AC traction electrification system. The model consists of the supply, the Scott- and auto-transformers, and the catenary system. The motor is simulated as an asynchronous machine. The v/f control is used for achieving the motor speed. The model is carried out in PSCAD/EMTDC. Analysis of simulation results are introduced, which pointed out the accuracy of the proposed model for the traction load, drives, and train movement. The results show that the model can be a designing and planning tool for the AC electric railway electrification system.
