Embodiment Construction

[0065] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0066] In this example, see figure 1 As shown, the present invention proposes a matching control method of a virtual rail transit train distributed power supply system, comprising steps:

[0067] S11. Calculate the normal and emergency running conditions of different trains according to the line conditions and vehicle parameters;

[0068] S12. According to the driving industrial control, match the motor train unit and each trailer unit in the distributed power supply system to obtain a matching scheme;

[0069] S13, formulate a control strategy according to the distributed power supply matching scheme, and control the operation status of each distributed power supply system of the train.

[0070] As an optimization scheme of the above-mentioned embodiment, in step S11, ...

Abstract

The invention discloses a distributed power system for virtual rail transit trains and a matching control method, and belongs to the technical field of rail transit trains. The method includes the steps of calculating the running conditions of different compartments according to line conditions and train parameters; conducting matching optimization on distributed energy storage packs in the distributed power system according to the running conditions and constraints to obtain a matching scheme; making a distributed power system control strategy according to the matching result, and controllingthe energy output of the train distributed power system through a train energy management controller and an energy storage pack management system. The distributed power system for virtual rail transit trains and the matching control method can realize flexible marshalling combination of virtual rail trains and improve the power supply reliability and the emergency power supply capability.

Description

technical field [0001] The invention belongs to the technical field of rail transit trains, and in particular relates to a virtual rail transit train distributed power supply system and a matching control method. Background technique [0002] Virtual rail transit does not need to lay physical tracks and set up waiting platforms. It has the characteristics of flexible control of urban public transportation and the characteristics of large traffic volume of urban rail transit such as subways and light rails. It perfectly combines the advantages of both. Flexible marshalling transport organization means that according to the passenger flow characteristics of urban rail transit in different sections and time periods, under the condition of ensuring a high train service frequency, by flexibly changing the length of the train marshalling at the depot or station to achieve the optimum passenger flow demand and transport capacity. The best coordinated transportation organization tec...
