There are a series of problems such as short distance between urban rail transit stations, large energy consumption, and heat treatment difficulty when trains start and stop. By optimizing the interval time and improving the efficiency of the regenerative braking energy of subway trains, these problems can be solved. In this paper, the primary entry point of the analysis is the condition of “traction -- idling -- braking” in the inter-station block partition. The energy utilization rate of the regenerative brake is calculated by using the overlapping time of the front and rear vehicle traction brakes. The utilization rate of the regenerative braking energy is expressed by the area method. On this basis, a model of 12 operating conditions is established, and the total traction power of train operation minus regenerative braking energy is taken as the objective function, and the train travel time, stop time, departure interval time, and other constraints are taken as constraints, and an optimization model of regenerative braking energy utilization of subway train based on block partition is designed.
