Optimization Configuration Method of On-board Super Capacitor for Urban Railway Transit

From aspects of power,capacity and the optimal discharge depth,the theory and optimal configuration of on-board super capacitor are studied to meet the vehicle braking energy recovery of urban rail transit.Through analyzing the super capacitor energy storage configuration method,a calculation method of minimum capacitance? and the optimal discharge depth is obtained,which shows that on the premise of meeting the energy storage,the capacitance capacitor device should be controlled in the smallest number.Example analysis indicates that super capacitor energy storage device capacitance device should not only consider the power and capacity requirements,but also consider the configuration of capacitance and the depth of discharge.
