Embodiment Construction

[0029] The preferred embodiments will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0030] The scheme adopted in the present invention is based on the following assumptions:

[0031] 1. The timetable information in the model has been determined, and what is adjusted is the external force on the train and the operation strategy of the train.

[0032] 2. The trains are all in the same power supply section, and the regenerative braking energy generated by the braking train can be used by other trains.

[0033] 3. The braking energy is fed back to the catenary and can be used by the traction train in time. If there is no traction train at this time, the braking energy produced will be consumed by the resistance.

[0034] 4. Each train decides the operation strategy of this section when it departs. If ev...

Abstract

The invention discloses an energy-saving optimization method for cooperative control on multiple trains. The method comprises the steps of adopting a stop position of each station on a train running route as a decision position of a train, and adopting the train passing by the decision position at the current moment as a decision train; acquiring the information of other trains in the same power supply interval at the current moment by the decision train; setting a decision strategy of all trains at a next moment in the same power supply interval; calculating renewable kinetic energy of all the trains in the same power supply interval; determining the decision strategy of the decision train at the next moment according to the renewable kinetic energy. By adopting the method, the utilization of renewable brake energy is realized, and the total energy consumption of all the trains on the route can be reduced.

Description

technical field [0001] The invention belongs to the technical field of train operation control, and in particular relates to an energy-saving optimization method for coordinated control of multiple trains. Background technique [0002] With the rapid development of urban rail transit in my country, urban rail transit, as the main means of transportation for modern people, plays an important role in people's lives. Under the background of the global development of low-carbon economy, urban rail transit, as the main line of urban public transportation and the main artery of passenger flow, consumes a lot of energy. Therefore, the research on energy-saving technology is undoubtedly of great practical significance. Energy saving has become one of the important goals of train optimization, which is mainly studied and improved from the energy-saving optimized driving of a single train and the coordinated control of multiple trains. [0003] The energy-saving driving of a single t...
