摘要
铁路机车运行能耗对铁路运输成本具有重要影响,为定量分析机车能耗的影响因素,通过利用牵引电算软件,对不同机车能耗影响因素进行仿真和对比研究,从坡道设计、停站次数、牵引总重、编组辆数、惰行距离5个方面定量分析各影响因素对机车运行能耗的影响。试验表明:坡度越大、停站次数越多、牵引总重越大、编组辆数越多、惰行距离越短,其能耗越大,反之越小。机车运行能耗影响因素仿真研究结论为合理确定机车能耗水平、优化线路设计、节能运营组织提供了更为直观的参考依据。
The energy consumption of locomotive operation has a crucial impact on the cost of railway transportation. Based on the electric calculation software for electric traction, this paper uses the computer simulation technology to set up different simulation environments respectively and makes the quantitative study on each influence factor for the energy consumption of locomotive operation in terms of ramp design, number of stops, total traction weight, number of formation cars, and coasting distance, drawing a conclusion on the importance and sensitivity of each factor for energy consumption. Through the quantitative analysis instead of qualitative analysis to settle key problems, a more intuitive reference and basis can be provided for reasonably determining the energy consumption level of locomotives, optimizing track design, and achieving energy saving in operation organization.
