Ground energy storage method for regenerative braking energy of long ramp

The invention relates to the technical field of energy storage, in particular to a ground energy storage method for regenerative braking energy on a long ramp, when a train runs on a ramp down from the long ramp, a super-capacitor energy storage device is controlled to charge and absorb regenerative braking energy generated by the train, so that the voltage of a contact network is reduced, and the voltage of the contact network is recovered to a normal range; when the train travels on the long ramp, the super-capacitor energy storage device is controlled to release electric energy, the contact voltage is increased, and the voltage of the overhead line system is recovered to be within the normal range; therefore, the regenerative braking of the train is ensured not to fail, and the running safety of the train and the regenerative braking energy utilization rate are improved. 本发明涉及储能技术领域，尤其涉及一种长大坡道再生制动能量地面储能的方法，当列车行驶在长大坡道下坡道时，控制超级电容储能装置进行充电，吸收列车所产生的再生制动能量，从而降低接触网电压，使得接触网电压恢复至正常范围；当列车行驶在长大坡道上坡道时，控制超级电容储能装置释放电能，提
