Ground hybrid energy storage system for urban rail transit

The utility model discloses a ground hybrid energy storage system for urban rail transit, and belongs to the technical field of energy management. Comprising a regeneration feeder cabinet and a regeneration cathode cabinet, the regeneration feeder cabinet and the regeneration cathode cabinet are electrically connected with a DCP converter cabinet, the DCP converter cabinet is electrically connected with an energy storage cabinet, and the energy storage cabinet is electrically connected with a control cabinet. The energy storage device can reduce ripples of voltage of a high-voltage side, is provided with the battery cabinet and the super capacitor cabinet, and has certain peak clipping and voltage stabilizing capabilities while ensuring the regenerative braking energy recovery performance of the energy storage device. The emergency traction function is achieved, when a direct-current power supply network is powered off due to urban power grid faults, power can be supplied to the power supply network, a train
