The invention particularly relates to a capacity configuration scheme of an unmanned subway ground type super-capacitor energy storage system, which belongs to the technical field of urban rail transit regenerative braking energy storage and utilization. Single-vehicle regenerative braking energy is obtained according to the unmanned subway train load, the auxiliary power and the braking characteristic curve, residual regenerative braking energy of multiple vehicles in the power supply interval of the super-capacitor energy storage system is calculated in combination with the running chart andthe line information, and the capacity of the ground super-capacitor energy storage system is configured; whether the system capacity configuration needs to be adjusted or not is determined by judging whether the residual regenerative braking energy is completely absorbed or not, finally, an optimization objective function is established according to the energy-saving efficiency and the investment cost of the configuration scheme, the capacity configuration scheme is adjusted with the minimum objective function value as the optimal value, and therefore the optimal configuration of the capacity of the super-capacitor energy storage system is achieved.
