Reliability and Maintainability Symposium (RAMS), Annual, 2009
5000kM high-speed railways with speed of 350km/h are being constructed in China in the next five years. A high-speed railway has many traction power substations (TPS) which convert the high voltage electricity of the public bulk power system to 25kV single phase electricity and supply it to the high-speed locomotives through the catenary system.

Modeling of influence of traction power supply system on railway automatics devices
2017 International Symposium on Electromagnetic Compatibility - EMC EUROPE, 2017A mathematical model of a. c. traction power supply system had been improved. It can be stated as a scientific base for the measurement method of harmonics of the return traction current. The track circuits work in the worst conditions situated near traction substations and locomotives, because the current of harmonics interferences will be greatest ...
