“…More important, passenger safety can not be guaranteed, trapping in the compartment for a long time [1]. To avoid this dilemma, a number of vehicle manufactures have proposed emergency traction technologies [2], which means that trains are only powered by on‐board energy storage systems (OESS) to take passengers to the nearest stations when a power outage occurs.…”

A power outage occurs when there is an interruption to traction power system. In such emergency situations, trains are expected to achieve autonomy operation powered by on‐board energy storage systems (OESS). This paper presents optimization models and methods to find optimal driving strategies for train emergency operation. Specifically, a nonlinear and non‐convex program is first formulated in space‐domain to minimize trip time under the limits of power and energy capacity of OESS. To improve computational efficiency, the time dynamics is removed from constraints and adjoined to the cost function. Furthermore, convex modelling steps are proposed to reformulate the problem as a convex program that can be solved efficiently. A bi‐level algorithm is designed to obtain optimal driving strategies that can arrive at destinations as soon as possible. Compared to energy‐optimal driving strategies, the proposed methods can effectively reduce the trip time.

“…To this end, a number of vehicle manufacturers are conducting research on emergency traction of vehicle batteries, and there are practical applications. 3 The Hitachi Research Institute cooperated with the Tokyo Metro Co., Ltd. to carry out the driving test of the train during emergency power supply. The test train was a 6-knot train on the Ginza line; when the driver switched the button to the emergency mode, he can continue driving for 1.2 km and take passengers to the nearest station.…”

Urban rail vehicle power supply short interruptions or prolonged paralysis situation sometimes occurs, which will cause the entire line outage. If the train through the battery to achieve emergency traction, it will be able to effectively solve the problem of train interval stop due to external power supply reasons. This article proposes an emergency traction system, using lithium-ion batteries as traction power, carrying out the design and research on the function of lithium-ion emergency traction system for rail transit vehicles. Through the design of the power supply system, the design of the emergency traction power supply, the design of the conversion control and safety protection circuit, the design of the traction system, and the design of the auxiliary system, the train can be run to the next station under the emergency power supply, and the effectiveness of the scheme is verified by simulation. Moreover, the transformation on the basis of the existing Shanghai 952 train illustrates the feasibility of the existing train to achieve the emergency traction function and provides guarantee for the safe operation of the train.
