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

Abstract

The invention discloses a train brake recovery system and method and a train. The system comprises a traction net, a train and an energy storage electric station, wherein the train comprises an electric brake, a battery, a charging capacitor, a power distributor, a first two-way DC / DC converter, a second two-way DC / DC converter and a first controller, wherein the power distributor is connected with the electric brake; a node is formed between the power distributor and the electric brake; one end of the first two-way DC / DC converter is connected with the battery; the other end of the first two-way DC / DC converter is connected with the node; one end of the second two-way DC / DC converter is connected with the charging capacitor; the other end of the second two-way DC / DC converter is connected with the node; the first controller is used for controlling the battery or the charging capacitor to absorb the braking electric energy according to the voltage of the traction net during the train braking; the energy storage electric station is connected with the traction net; a second controller of the energy storage electric station controls the energy storage electric station to perform charging or discharging according to the voltage of the traction net. The charging and the discharging of the battery, the charging capacitor and the energy storage electric station are controlled through monitoring the voltage of the traction net; the recovery and the reutilization of the braking electric energy can be realized; the energy sources are effectively saved.

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...
