Train brake recovery system, control center for train dispatching and method

Abstract

The invention discloses a train brake recovery system, a control center for train dispatching and a method. The system comprises a traction net, trains, energy storage electric stations and a control center, wherein the traction net comprises a plurality of sections; each 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 power distributor and the electric brake; 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 energy storage electric stations are connected with the traction net; at least one energy storage electric station is arranged in each section; the control center is used for obtaining the operation state of the plurality of trains operating on the traction net, judging whether a line fault occurs or not in the section, and controlling the at least one energy storage electric station corresponding to the section generating the line fault to perform discharging when the condition that the line fault occurs at the section is judged. Therefore, when any one section generates the line fault and cannot supply electricity to the trains, the energy storage electric stations of the section are used for emergency power supply; the normal operation of the train is ensured.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a train braking recovery system, a control center for train dispatching, a train braking recovery method and a control method for train dispatching. 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...

AI Technical Summary

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
