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. The system comprises a traction net and an energy storage electric station, wherein the energy storage electric station is connected with the traction net, and comprises a two-way DC/DC converter and a controller; the controller is used for controlling the two-way DC/DC converter according to the voltage of the traction net so as to control the energy storage electric station to perform charging or discharging. According to the embodiment of the invention, the braking electric energy is absorbed through the energy storage electric station, so that the recovery and the reutilization of the braking electric energy are realized; the energy source waste is reduced; the traction net load is reduced; the voltage of the traction net is effectively monitored; parts of the system are protected; the damage of electric appliances on the traction net is avoided; the system safety is improved. The embodiment of the invention also provides the energy storage electric station and a control center for train dispatching.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a train brake recovery system, an energy storage power station, a control center for train dispatching 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 ...
