摘要
为落实“碳达峰、碳中和”相关政策要求,基于目前我国城市轨道交通发展现状,分析了国内城市轨道交通的能耗特点及现状,展开轨道交通绿色低碳发展可行路径的研究。本文主要对通风系统运行模式以及通风系统风机运行情况进行分析研究,并提出具体对策,从而降低碳排放,加快绿色低碳转型。首先,根据具体地铁客流情况分布,对地铁站通风系统运行模式分析,建立客流数据监测云平台,采用小新风模式、全新风模式,制定合理时间表;其次,根据通风系统风机运行情况,并结合客流因素建立CART决策树优化模型,对地铁站内风机设备的运行数据和客流数据进行分析、计算、研究,制定出大系统合理的运行方式;最后,通过实验验证表明,通过本次研究,能够加快轨道交通绿色低碳转型,为推进城轨行业做好“碳达峰、碳中和”工作提供借鉴。
In order to implement the relevant policy requirements of"carbon peak and carbon neutrality",based on the current development status of urban rail transit in China,the energy consumption characteristics and current situation of domestic urban rail transit were analyzed,and the feasible path of green and low-carbon development of rail transit was studied.This paper mainly analyzes and studies the operation mode of the ventilation system and the operation of the ventilation system fan,and proposes specific countermeasures to reduce carbon emissions and accelerate the green and low-carbon transformation.First of all,according to the specific distribution of subway passenger flow,the operation mode of the ventilation system of the subway station was analyzed,the passenger flow data monitoring cloud platform was established,and the small fresh air mode and fresh air mode were adopted to formulate a reasonable timetable.Secondly,according to the operation of the fan of the ventilation system,and combined with the passenger flow factor,the CART decision tree optimization model was established,and the operation data and passenger flow data of the fan equipment in the subway station were analyzed,calculated and studied,and the reasonable operation mode of the large system was formulated.Finally,the experimental verification shows that through this study,the green and low-carbon transformation of rail transit can be accelerated,and it can provide reference for promoting the urban rail industry to do a good job of"carbon peak and carbon neutrality".
