Problems solved by technology

Reduce energy consumption by finding the best running state of trains, but most of the schemes do not consider the actual line conditions, and mostly assume straight roads, which are quite different from the actual operating line standards

Embodiment 1

[0100] The adjustment method of the high-speed railway train operation diagram based on the energy saving of the stop plan includes the following steps:

[0101] 1) Analyze the travel situation of passengers on holidays and non-holidays, and determine the stopping rate of each station according to the daily average number of passengers sent by each station;

[0102] 2) Use traction calculation software to calculate the energy consumption value added by high-speed railway train stops at each intermediate station;

[0103] 3) Under the constraints of the safety interval and stopping time of high-speed railway trains, a dual-objective model with the shortest total travel time and energy saving is established;

[0104] 4) Using fuzzy mathematical programming method to solve the dual-objective model;

[0105] 5) According to the relationship between the energy consumption value and the stop plan, give the adjustment suggestion for the stop plan based on energy saving.

Embodiment 2

[0166] Based on Embodiment 1, this embodiment selects the Nanjing South-Shanghai Hongqiao section in the non-holiday Beijing-Shanghai high-speed railway (such as image 3 shown), the technical solution will be described.

[0167] Specifically, there are 20 high-speed trains in the downward direction (the maximum speed is 300km / h). The selected trains have stops at Nanjing South and Shanghai Hongqiao. Therefore, Nanjing South is used as the starting station and Shanghai Hongqiao as the final station. , namely: β 1 =1, β 8 = 1; in addition, according to the safety interval standard of the existing timetable and the parameter values ​​of the study case selected according to the passenger flow demand (as shown in Table 2), the train traction calculation software is used to calculate the distance between Zhenjiang South, Danyang North, Changzhou North and Wuxi respectively. The parking of the 6 intermediate stations in the east, Suzhou north and Kunshan south increases the energy...

Embodiment 3

[0193] (1) Calculation of stop rate

[0194] For the calculation of the stop rate, where is the daily average number of passengers arriving and departing from station s, that is, the daily average passenger volume of each station, and the daily average passenger volume of each station in the Nanjing South-Shanghai Hongqiao section of the Beijing-Shanghai high-speed rail (as shown in Table 7).

[0195] Table 7 Average daily passenger flow of each station

[0196]

[0197] In order to simplify the calculation process, the passenger flow density k in this section is taken as the average passenger flow density of the Beijing-Shanghai high-speed railway of 45.12 million people / km. According to the 12306 official website query, it can be obtained that the number of high-speed trains running on the Beijing-Shanghai high-speed railway in this section is 49, so I takes The value is 49. According to formula (1-1)

[0198]

[0199] Since Nanjing South Railway Station and Shangh...

Abstract

The invention discloses an energy-saving adjustment method for a high-speed railway train running diagram based on a stop scheme, and belongs to the technical field of high-speed railway train running schemes. In the invention, the station stopping rate is determined based on passenger flow, the energy consumption value added by train stops at each intermediate station is calculated, a dual-objective optimization model (minimum travel time and minimum energy consumption value) is established, and the high-speed railway train stop plan and energy consumption are combined. The correlation between the consumption value gives suggestions for stop adjustment, so that high-speed railway trains can achieve energy saving and emission reduction under the premise of meeting the safety interval and passenger flow demand, etc., and also reduce train travel time, improve the line capacity and passenger travel. comfort.

Description

technical field [0001] The invention relates to a timetable adjustment method of a high-speed railway train, in particular to a method for adjusting the operation diagram of a high-speed railway train based on an energy-saving stop scheme, and belongs to the technical field of the high-speed railway train running scheme. Background technique [0002] At present, the methods for reducing the energy consumption of high-speed railway trains in my country mainly include: 1. Adjusting the running time of high-speed railway trains. In general, the train running time directly affects the traction energy consumption. However, under the premise of meeting the safety interval, the running time of high-speed railway trains has little room for adjustment; or, although the running time is adjusted, the resulting timetable It has a great impact on the passing capacity of the line and the time cost of passengers. 2. Optimize the driving of high-speed railway trains. The energy consumptio...
