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 and a train, wherein the train comprises an electric brake, a battery, a power distributor, a two-way DC / DC converter and a first controller; the power distributor is connected with the electric brake; a node is formed between the electric brake and the power distributor; one end of the two-way DC / DC converter is connected with the battery; the other end of the two-way DC / DC converter is connected with the node; the first controller is used for controlling the power distributor and the two-way DC / DC converter for feeding the braking electric energy back to the traction net during the train braking, controlling the two-way DC / DC converter to absorb the train braking electric energy through the battery according to the voltage of the traction net, controlling the power distributor to be switched off when the electric energy cannot be obtained from the traction net and controlling the two-way DC / DC converter so that the battery can supply the electricity to the train. According to the embodiment of the invention, the battery on the train is used for absorbing the braking electric energy; the emergency driving on the train is realized through the battery, so that the recovery and utilization of the braking electric energy can be realized; the energy source waste is reduced; in addition, the problem of dispatching difficulty due to halfway break down of the train is solved.

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...
