    Abstract: Introduction was made to the structure of super-capacitor energy storage systems and functional characteristics of bi-directional DC-DC converters. This paper enacted the voltage outer ring of bi-directional DC-DC converters and current inner ring of double PI control strategy. During the initialization phase, the traction network voltage dropped and the super-capacitor output energy; during the train deboost phase, the traction network voltage rose and the super-capacitor absorbed energy. The 1 500 V DC-electrified railway simulation platform was established and carried out simulation. The simulation result verifies that the super-capacitor energy storage system absorbs the regenerative braking energy and reduces the loss of subway energy, which effectively controls the traction network voltage’s fall and rise.
    Key words: urban railway transit; ultra-capacitor; bi-directional DC-DC converter
