| Summary: | Electric braking of urban rail vehicle produces considerable regenerative braking energy and secondary utilization of the surplus regenerative braking energy can improve energy saving rate of the system. This paper proposed a modularized super capacitor energy storage system. By using low voltage and high frequency converter modules, and connecting the converter modules in series and parallel, the energy storage system realizes two-way flow, stable charging and discharging voltage and current through the DC voltage division control of the series system. which can make the system respond quickly and the charging response time of the system is not more than 100 ms. Experimental verification of the proposed theoretical scheme on a 300 kW super capacitor energy storage device is carried out and the results show that its average power saving is 25 kW·h per day and the energy saving effect is good. |
