Method, system and device for site selection of ground energy storage for urban rail transit

Abstract

The invention relates to a site selection method, system and device for urban rail transit ground energy storage. The method includes the following steps: (1) Obtaining train operating parameters during off-peak hours, including the number of operating trains and the average operating cycle of each train; (2) ) respectively calculate the piezoresistance number of each station, and the piezoresistance number is the sum of the number of times the brake resistor is turned on and the number of low voltage occurrences at the station when all trains run to the station in the full operation cycle; (3) according to the peak The piezoresistive number threshold is determined by the train operating parameters in the time period; (4) The station with the piezoresistive number not less than the piezoresistive number threshold is selected as the ground energy storage installation point. Compared with the prior art, the present invention can provide guidance for rapid and reasonable site selection of the urban rail transit ground energy storage system, and has the characteristics of little influence by working conditions and operation diagrams and good universality.

AI Technical Summary

Problems solved by technology

The results of literature analysis show that the engineering usability of the current urban rail transit ground energy storage site selection research needs to be improved, mainly in the following aspects: the site selection method is not user-friendly, the workload is huge, and the site selection period is long; there are no sensitive characteristic parameter indicators As a guide; method theory cannot be applied to multi-working conditions and diversity of different lines

These factors not only affect the accuracy of site selection, but also waste a lot of manpower, material and financial resources, which are not economical and universal
