The invention discloses a superconducting magnetic energy storage device applied to regenerative braking of a subway train and is connected with a traction power supply system. The device comprises apower conversion module, an energy storage module and a measurement and control unit, wherein the measurement and control unit is used for judging the current working modes of the traction power supply system and the superconducting magnetic energy storage device and controlling the working state of the power conversion module, so the energy storage module can absorb and store energy automaticallygenerated by train regeneration and release electric energy to the traction network under the traction working condition of the train, and thereby energy is provided for the train. The device can fully absorb excess energy generated during train braking and effectively store the excess energy with low loss, the excess energy is fed back to a traction network to be used by a train under the traction working condition of the train, the network voltage is stabilized while the regenerative braking energy of the train is reasonably utilized, the electric energy quality is improved, and power supply reliability is improved. The invention further discloses a control method of the device.
