Traction Power

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.
