Abstract

Abstract: Based on the distribution characteristics of neutral zones of tractive power supply system, a data-driven approach dealing with high speed trains' stopping in the neutral zone was proposed and the processing system was established, which can greatly improve the emergency efficiency and effectiveness of decision. The proposed approach can also mitigate the accident caused by the improper dealing methods that could cause the overhead line burn down. According to historical data, the problems dispatchers dealt with were combed, and the key factors, which affected the efficiency of emergency response and cause safety risks were analyzed. Therefore, based on the line data and the information of overhead contact line, visualization solution, including train control strategies, was shown to deal with the problem of stopping in the neutral zone. The results show that based on the proposed approach, the time dealing with trains' stopping in the neutral zone can be quartered, which can largely increase the emergency response efficiency.

Key words: high speed railway, electric multiple units(EMU), neutral zone, emergency response, data-driven
