Arc burning phenomenon of insulated rail joint at cut-off point is one of important challenges in high-speed railway (HSR) stations. In order to study this issue in specific, by utilizing MATLAB/Simulink software, the equivalent integration model of electric multiple units (EMU) running in the station traction network is established to perform simulation analysis. The actual traction power supply...
The High Speed/High Capacity railway lines uses the 2×25 kV − 50Hz power supply system that is supplied at high-voltage by dedicated lines that can be placed in close proximity to the railway line. The power system adopted for High Speed railway lines includes a lot of sources of disturbance and inject harmonic components in signaling circuits. This paper presents a detailed model for the railway...
A 2 25-kV 50 Hz traction power system was analyzed and modeled in the time domain in order to simulate short-circuit conditions and to attain a practical method to identify the short circuit behavior of the traction system. In particular, due to the difficulty in assessing the track-line parameters which mainly depend on changing environmental conditions, the possibility of neglecting the...
