铁路运输是化工物流主要的运输方式之一,从能源消耗的绝对量来看,铁路运输的能耗量巨大,是节能的重点行业。以列车在区间运行总能耗最低为优化目标,在考虑线路类型、闭塞方式的基础上,对区间运行时间、车站作业时间、区间速度、车站间隔时间和追踪列车间隔时间加以约束,建立了节能运行图编制优化的模型,并结合算例进行了验证。计算结果显示,当采用此方案优化时,在略微增加列车运行时间的基础上,大大减少了总的运营成本,得到很好的节能减排效果。
Railway transportation is one of the main modes of transport for chemical logistics. From the perspective of the absolute amount of energy consumption, rail transportation consumes a huge amount of energy and is a key energy-saving industry. Taking the minimum total energy consumption of the train in the interval as the optimization objective, the interval operation time, the station operation time, the interval speed, the station separation time and the tracing train separation time are constrained based on the type of the line and the occlusion method, and energy saving is established The diagram of running graph is optimized and validated by the example. The calculation results show that when this scheme is optimized, the total operation cost is greatly reduced and the effect of energy-saving and emission reduction is obtained with a slight increase of train running time.
