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, a plurality of trains and a control center, wherein the plurality of trains are connected onto the traction net; 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 first controller is used for controlling the power distributor and the two-way DC / DC converter to feed back the braking electric energy to the traction net during the train braking; the control center is used for obtaining the state of the traction net; when the traction net fails, the batteries of the plurality of trains are controlled to perform discharging so as to supply electricity to the trains; meanwhile, the plurality of trains are subjected to emergency dispatching. Therefore, when the traction net fails, passengers in the trains operating on the traction net can be safely brought out to the station through emergency dispatching; the safety of users 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
