"双碳"目标下山区铁路线路参数对列车牵引碳排放的影响
Impact of Railway Line Parameters in Mountainous Areas on Train Traction Carbon Emissions under the Dual Carbon Target
摘要
Abstract
The major source of carbon emissions during the whole life cycle of railways in mountainous areas is the energy consumption of trains during the operation phase,and the railway line parameters have different impacts on this part of carbon emissions.To consider this part of carbon emissions at the design stage,this paper establishes a train-track longitudinal dynamics model to calculate the energy consumption per unit mileage of CRH1 electric multiple units under different railway line parameters in mountainous areas,and then converts it into carbon emissions for analysis.Calculation results show that station spacing is the factor with the greatest influence,which has a secondary effect on carbon emissions per unit mileage,and this effect gradually decreases with the increase of station spacing;slope gradient,slope length,and control speed have a linear positive correlation with carbon emissions per unit mileage,while the influence of curve radius is negligible.关键词
