By analyzing the necessity of setting up the on-board energy storage system of rail transit vehicles, the rationality of using the super capacitor type energy storage system is put forward. The model of braking energy storage system for urban rail transit vehicles is established. The working principle of braking energy storage system is introduced, and the selection criteria of the main components are analyzed. The selection of super capacitor voltage range, supercapacitor capacity, supercapacitor Determination of the amount and inductance. The size of regenerative braking energy is calculated through simulation, and the optimal initial charging voltage is determined based on the power-capacitance constraint. The optimal configuration of the supercapacitor array is completed, which provides a theoretical basis for the overall structural design of the energy storage system and the selection of inductors and capacitors .
