Nowadays, the development of urban rail transit is getting faster and faster, but its consequent electric consumption problem is getting more attention, and how to better solve the problem of regenerative braking energy absorption and utilization, which accounts for a larger portion of electric consumption, is gradually becoming one of the hot spots of research nowadays. This paper adopts energy storage technology and designs a wayside energy storage system (WESS). Firstly, the commonly used topologies of energy storage converters are compared, and finally a three-phase staggered parallel fly-across capacitor DC/DC converter is selected as the topology of energy storage converter; then its working characteristics are described from the three-level technology and staggered parallel technology respectively; then the WESS is added into the existing traction power supply system and MATLAB simulation is established. Finally, the simulation is carried out to verify the characteristics of the energy storage converter and the regenerative braking energy absorption effect. The results show that the designed WESS can be better adapted to the actual operation of urban railways and achieve the maximum utilization of energy, which provides good technical support for its energy-saving operation.
