Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many of the details listed in the specification are only for readers to have a thorough understanding of one or more aspects of the invention, and these aspects of the invention can be practiced without these specific details.

[0026] like figure 1 As shown, during the operation of urban rail transit trains, a considerable part of the energy is consumed by line resistance. However, due to the large differences in the line environment of each operating interval, the energy consumed by the train in different operating intervals is different. The composition of traction energy consumption, such as figure 1 As shown, the traction energy consumption of the train is generated by the basic resistance of the train r...

Abstract

The invention discloses an energy-saving optimization operation method of urban rail transit trains. The train running time of each operation section is obtained by analyzing statistical data. Energyconsumption function, and forecast the capacity of each section, optimize and adjust the distribution of the total running time of the train in each running section, The expression of the total energyconsumption function of the train on the whole line is obtained, and the minimum energy consumption of the train on the whole line is taken as the optimization objective, the running time of the train on each running section is optimized, and the optimized running time of each section is obtained, which is used to generate the traction curve of the train, so as to achieve the purpose of energy saving. The invention can effectively reduce the traction energy consumption of the urban rail transit train, reduce the operation cost of the subway operation enterprise, has strong operability and does not cause additional burden to the operation enterprise.

Description

technical field [0001] The invention belongs to the technical field of energy-saving control of urban rail transit vehicles, and in particular relates to an energy-saving and optimized operation method for urban rail transit trains. Background technique [0002] At present, the running schedule of trains in each operating section is determined according to the line length, speed limit range and other factors of the operating section, mainly to meet the safety of train operation and passenger convenience as the starting point, and seldom consider the energy-saving optimization of trains . Foreign scholars are studying Madrid-Guadalajara, Guadalajara-Calatayud and Calatayud-Zaragoza The time optimization of the three operating sections of the same section of the railway is carried out. While maintaining the overall operating time at 1 hour and 28 minutes, changing the operating time of each section can achieve the highest energy saving goal of 33.63%. However, there are many...
