| Abstract: | A new energy storage device based on super capacitor, which provides traction for the train or absorbs the transient energy during regenerative braking through the bi-directional DC-DC converter, is proposed to solve the problem of the DC bus voltage impact caused by the train starting and braking. The composition and design method of the super capacitor energy storage device are described. Then the control strategy of the super capacitor energy storage system during charging and discharging is represented. The simulation platform of the 750 V DC electrified railway model is formed. The simulation results demonstrate the super-capacitor energy storage system is able to maintain the DC bus voltage, effectively prevent the load fluctuations in the power system of the subway and avoid waste of regenerative braking energy. |
