Problems solved by technology
However, the braking electric energy generated when the train brakes is very large. If it is to be absorbed by the on-board battery, a large number of batteries need to be installed on the train, which will not only seriously increase the weight of the train, affect the energy consumption of the train, but also increase the necessary cost

The invention discloses a brake recovery system and method for a train and the train. The system includes: a traction network, a train and an energy storage power station, wherein the energy storage power station is connected to the traction network, the energy storage power station includes a second controller, and the energy storage power station includes a second controller. The second controller controls the energy storage power station to charge or discharge according to the voltage of the traction network. The train includes: electric brake; battery; distributor, which is connected to the electric brake, and there is a node between them; It is connected to the battery, and its other end is connected to the node; the first controller is used to control the distributor and the bidirectional DC / DC converter to feed back the braking electric energy to the traction grid when the train is braking, and control the power supply according to the voltage of the traction grid The bidirectional DC / DC converter absorbs the braking electric energy of the train through the battery. The invention controls the charging and discharging of the battery and the energy storage power station by monitoring the voltage of the traction network, realizes the recovery and reuse of braking electric energy, effectively saves energy, effectively controls the voltage of the traction network, and improves safety.
Description
technical field [0001] The invention relates to the technical field of rail transit, in particular to a train brake recovery system, a train with the system and a train brake recovery method. Background technique [0002] With the continuous expansion of the city scale, traffic congestion is increasing, rail trains, such as light rail, subway, etc., have become the main means of transportation in many cities. During the braking process of the train, a large amount of braking electric energy will be generated. With the deepening of the concept of green and environmental protection, the problem of recovering and reusing the braking electric energy of the train has become very urgent. At present, relevant technologies are disclosed, and batteries are installed in trains to recover braking electric energy and supply power to trains. However, the braking electric energy generated when the train brakes is very large. If it is to be absorbed by the on-board battery, a large number...
