A train schedule adjustment method and system based on invalid stop time allocation

Abstract

The invention relates to the technical field of railway dispatching, in particular to a train schedule adjustment method and system based on invalid stop time allocation. The method includes: calculating the effective stop time and the invalid stop time; dividing the invalid stop time into equal parts, and distributing the equalized invalid stop time to the train diagram one by one, calculating the energy consumption reduction ratio, and finding the optimal energy drop ratio; according to the optimal energy drop ratio obtained, the optimized train diagram is obtained; the optimized train diagram is subjected to stability judgment, if the stability judgment is satisfied, then the train diagram is the target train operation picture. The invention adjusts the stop time on the basis of ensuring the stability of the front and rear train schedules. Judging whether there is an invalid stop time for the train, and allocating the invalid stop time not only ensures the safety interval of the train, station operation, passenger boarding and landing and other related constraints, but also reduces the energy consumption of the train operation and reduces the operating cost of the railway.

Description

technical field [0001] The invention relates to the technical field of railway dispatching, in particular to a train schedule adjustment method and system based on invalid stop time allocation. Background technique [0002] Due to the rapid development of high-speed railways in recent years and the use of electrified railways. From the perspective of power supply, the higher the speed of the train, the greater the traction force required, and the greater the power consumption. Therefore, there is an inverse proportional relationship between the running speed of the train in the section and the energy consumption. The greater the train speed, the greater the energy consumption. [0003] At present, there are two main ways to save train energy consumption in my country: (1) Adjust the running time of trains. The method to achieve energy saving is generally divided into two aspects. On the one hand, in general, the running time of the train directly affects the traction energ...

AI Technical Summary

Problems solved by technology

However, most studies assume that trains run on straight tracks, or only consider single characteristics such as train characteristics, ramps, and curves, which are quite different from the actual operating line standards.

When optimizing train energy saving, most of the existing studies only aim at the minimum energy consumption of trains, and seldom consider train travel time
