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 method for adjusting the high-speed railway train diagram based on the energy saving of the stop scheme includes the following steps:

[0101] 1) Analyze the travel situation of passengers on holidays and non-holidays, and determine the stop rate of each station according to the average daily passenger volume of each station;

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

[0103] 3) Under the constraint of satisfying the safety interval and stop time of high-speed railway trains, establish a dual-objective model with the shortest total travel time and energy saving;

[0104] 4) Using the 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, a suggestion for adjusting the stop plan based on energy saving is given.

[0106] In st...

Embodiment 2

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

[0167] Specifically, it includes: a total of 20 high-speed trains (maximum speed 300km / h) in the down direction. The selected trains have stops at Nanjing South and Shanghai Hongqiao. Therefore, Nanjing South is used as the starting station and Shanghai Hongqiao is 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 research 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 the trains in Zhenjiang South, Danyang North, Changzhou North, and Wuxi respectively. Parking at 6 intermediate stations in East, Suzhou North and Kunshan South increases energy c...

Embodiment 3

[0192] (1) Calculation of stop rate

[0193] For the calculation of stop rate, where is the daily average number of passengers arriving and departing at station s, that is, the average daily passenger volume of each station, and the average daily passenger volume of each station in the Nanjing South-Shanghai Hongqiao section of the Beijing-Shanghai high-speed railway (as shown in Table 7).

[0194] Table 7 Average daily passenger flow of each station

[0195]

[0196] In order to simplify the calculation process, the value of the passenger flow density k in this section is the average passenger flow density of the Beijing-Shanghai high-speed railway, which is 45.12 million people / km. According to the query on the 12306 official website, the number of high-speed trains operating in this section of the Beijing-Shanghai high-speed railway is 49, so I is taken as The value is 49. According to formula (1-1)

[0197]

[0198] Since Nanjing South Railway Station and Shangha...

Abstract

The invention discloses an energy-saving high-speed railway train working diagram adjusting method based on a stop scheme, and belongs to the technical field of high-speed railway train running schemes. In the invention, the station stop rate is determined according to passenger flow, the energy consumption value increased by train stop of each intermediate station is calculated, a double-target optimization model (the travel time is the shortest and the energy consumption value is the smallest) is established, and stop adjustment suggestions are given in combination with the relevance betweena high-speed railway train stop scheme and the energy consumption value. On the premise that the high-speed railway train meets the requirements for safety intervals, passenger flow and the like, energy conservation and emission reduction are achieved, the train travel time is shortened, and the route passing capacity and the passenger travel comfort are improved.

Description

technical field [0001] The invention relates to a timetable adjustment method for high-speed railway trains, in particular to an adjustment method for high-speed railway train operation diagrams based on energy-saving stop schemes, and belongs to the technical field of high-speed railway train running schemes. Background technique [0002] At present, the methods to reduce the energy consumption of high-speed railway trains in my country mainly include: 1. Adjust the running time of high-speed railway trains. In general, train running time directly affects traction energy consumption. However, under the premise of satisfying the safety interval, there is almost no room for adjustment of the running time of high-speed trains; or, although the running time is adjusted, the obtained 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 consumption is reduced by find...
