TRAIN BRAKE RECOVERY SYSTEM AND METHOD AND TRAIN

WIPO Patent Application WO/2018/054007

A1

Disclosed are a train brake recovery system and method and a train. The system comprises: a traction network (1), a train (2), and an energy storage power station (3). The energy storage power station (3) is connected to the traction network (1), and comprises a second controller which controls, according to the voltage of the traction network (1), the energy storage power station (3) to charge or discharge. The train (2) comprises: an electric brake (201); a battery (202); a power distributor (203) connected to the electric brake (201), there being a node between the power distributor (203) and the electric brake (201); a bidirectional DC-DC converter (204), one end of which is connected to the battery (202) and the other end thereof is connected to the node; a first controller (205) used for controlling the power distributor (203) and the bidirectional DC-DC converter (204) to feed back braking electrical energy of the train (2) to the traction network (1) during braking of the train (2), and controlling, according to the voltage of the traction network (1), the bidirectional DC-DC converter (204) to absorb the braking electrical energy of the train (2) by means of the battery (202).
