Brake recuperation system for train, control center and method for train dispatching

Abstract

The invention discloses a train brake recovery system, a control center for train dispatching and a method. The system comprises a traction net, a train, a plurality of energy storage electric stations and a control center, 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; the first controller is used for controlling the power distributor and the two-way DC / DC converter to feed back braking electric energy to the traction net during the train braking; the energy storage electric stations are connected with the traction net; each energy storage electric station comprises a second controller; the second controllers are used for controlling the energy storage electric stations to perform discharging to the traction net when the voltage of the traction net is smaller than a first preset threshold value; the control center is used for obtaining the electric quantity of the plurality of energy storage electric stations and performing discharging power distribution according to the electric quantity of the plurality of energy storage electric stations. Therefore the plurality of energy storage electric stations can be controlled to perform balanced and harmonious work; when the plurality of energy storage electric stations are controlled to perform sufficient discharging, the over discharging of the energy storage electric stations can be effectively prevented; the service life of the battery 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
