Problems solved by technology

These methods are all qualitative energy-saving adjustments, which can achieve energy-saving effects during daily off-peak hours, but are less effective during peak hours, and cannot achieve the effect of effectively utilizing the regenerative energy of multiple trains, and do not consider the energy-saving utilization of trains. In addition, the method given by ATS Energy Saving has not been reflected in the specific timetable compilation work

Embodiment Construction

[0058]The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0059] The multi-train operation energy-saving optimization model refers to reducing the total energy consumption of multi-train operation under the constraints of the timetable. For each train, different operation strategies determine the energy consumption of the train, and for multiple trains as a whole, the proposal of regenerative braking energy makes the dispatching strategy between trains the key to energy saving.

Abstract

The invention discloses an urban rail transit ATS energy-saving time table compilation method. By analyzing energy-saving operation modes of a plurality of trains, decomposing operation stages and approximately calculating the available energy-saving operation overlapping time, train operation energy consumption is provided for energy consumption calculation; and in addition, the genetic algorithm is introduced, the aim of minimizing the total energy consumption is transformed into the aim of optimizing the optimal arriving time and departure time of the multiple trains, and the multiple trains are subjected to subsection calculation in an off-line calculation mode. An ATS energy-saving time table generated through the method can achieve the purpose of reducing the total operation energy consumption of the multiple trains.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to an urban rail transit ATS energy-saving schedule preparation method. Background technique [0002] In the urban rail transit signal control system, the train control system based on wireless communication (CBTC for short) has gradually become the mainstream. With the popularization of CBTC technology application, the biggest change of this signaling system is the change of train driving mode. [0003] According to statistics, during the operation of the subway, train energy consumption accounts for more than 50% of the total energy consumption. The existing energy-saving methods mainly include lightweight vehicles, reducing running resistance, improving power supply efficiency, energy-saving driving, and regenerative braking applications. Among them, the energy-saving timetable has the greatest impact on the energy consumption of multi-train operation. Realizing ener...
