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 brake recovery system for a train, a control center and a method for train dispatching, the system includes: a traction network; a train, the train includes: an electric brake; a battery; a distributor, the distributor Connected to the electric brake, there is a node between the distributor and the electric brake; a bidirectional DC / DC converter, one end of the bidirectional DC / DC converter is connected to the battery, and the bidirectional DC / DC The other end of the converter is connected to the node; a first controller; a plurality of energy storage power stations, the plurality of energy storage power stations are connected to the traction network; Monitoring is carried out, and when the substation fails, the plurality of energy storage power stations are controlled to discharge. Therefore, the embodiment of the present invention uses the energy storage power station on the traction network to provide emergency power supply when the substation fails to serve as the traction network to ensure the normal operation of the train.

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...
