Embodiment

[0091] Taking an actual subway line in urban rail transit as an example, the design steps of the train delay adjustment method considering energy consumption factors are as follows:

[0092] First, input the train operation scheduling data, train timetable data, train operation organization data, and train delay information to determine the simulation interval and simulation time. If the data is correct, the computer enters the E-Δt regression model analysis module;

[0093] Secondly, enter the E-Δt regression model analysis module, the specific steps include:

[0094] Step 1: Through actual measurement, the deviation Δt between the running time of each section of the train and the planned running time and the corresponding energy consumption value E are obtained.

[0095] Step 2: On the basis of the measured data, the regression equation of Δt and E is obtained through regression analysis, so as to determine the E-Δt regression model, and use this function model as one of the...

Abstract

The invention discloses an urban rail transit train delay adjustment method considering energy consumption influence factors. The method comprises the following steps: establishing a basic data module; establishing a regression equation of a deviation value delta t between different running time and planned running time of each interval of the train and interval running energy consumption E by utilizing a regression analysis method on the basis of the measured data, so as to determine an E-delta t regression mode; establishing a train delay adjustment model which comprises a delay train number model, a delay station model, a delay time model and a redundancy adjustment time model of subsequent interval stations; normalizing the total delay time of a train and the running energy consumption of the train, weighting to serve as a target function, taking train delay adjustment as a single-target optimization problem, and performing optimization adjustment after the train is delayed by adopting an improved particle swarm optimization IPSO, thereby determining an optimal adjustment strategy of the train. The invention provides data and theoretical support for delay adjustment of an actual train, and has relatively high use value and application prospect.

Description

technical field [0001] The invention belongs to the field of urban rail transit signal control, and in particular relates to an urban rail transit train delay adjustment method considering factors affecting energy consumption. Background technique [0002] The urban rail transit system as a whole presents the characteristics of giantization and networking, the actual operating conditions are becoming more and more complex, and the difficulty of operation management and control has increased sharply. Due to changes in passenger flow, equipment failures, emergencies and other factors in daily operations, trains are frequently delayed. If not adjusted in time, it will have a great impact on the operation quality and economic benefits of urban rail transit trains. Therefore, measures should be taken to adjust the train operation so that it can resume punctual operation as soon as possible. [0003] When the delay of the train is within a small range, the general train automatic...
