Start from Beijing-Tianjin intercity dedicated passenger line, a new 2 × 25 kV autotransformer feeding is applied to China high-speed railway. The traction power supply system is different from China common-speed electrified railway. In this paper, the traction power supply system, the course of fault isolation and supply recovery are introduced. According to normal operation and emergency operation,...
In view of the special structural characteristics of traction power supply system, the paper proposed a new method based on the principle of double-ended voltage travelling waves to make fault location. Double-ended travelling waves fault location avoids the drawbacks of impedance method, and it makes huge significance to the high-speed electrified railway of China. Application system of this method...
