Study on the Construction Rules and Sequencing Method of Train Operating Condition Sequence Based on Regenerative Energy

Abstract

Obtaining an effective sorting method for train operating conditions is the premise for studying the optimization method of renewable energy utilization in the operation of urban rail trains. But there are few studies in this field. So that, in this paper, firstly, based on the given running time of the train, the construction rules of the running condition sequence of the interval train are given for the interval of different speed limiting types. Then, based on the train operating condition sequence solution set obtained by the construction rules, the regenerative energy utilized in the traction phase of each sequence and the regenerative energy utilized in the braking phase are used as ranking indices, and the interval number is used to express the uncertainty of the two ranking indices. The interval numbers of all solutions are obtained and sorted by the TOPSIS method based on entropy weight, and the sequence values of all train operating conditions corresponding to the interval are obtained. Finally, an example is given to illustrate the practical application of this sorting method.
