Abstract

Low-frequency voltage fluctuations severely impact the equipment security and transportation order of Electrified Railway, which have been frequently reported in China Electrified Railway. In order to suppress such fluctuations, this paper presents an effective method by impedance regulation of the locomotive- Tpss(traction power supply system) interaction system which has been adopted in a practical railway Hub, Xuzhou Railway Hub in China. In this Hub, the original transformer of North Xuzhou substation has been replaced by an expanded one with a larger capacity and a smaller short circuit voltage to reduce the impedance of the interaction system. The practical operation shows that the reconstructed substation with proposed method successfully removed the voltage fluctuation. Furthermore, the feasibility of the mitigation technology is verified by the compared field tests.
