化工物流铁路运输节能策略研究

Research on Energy Conservation in Chemicals Logistics Rail Transport

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。

Rail transport is one of the main means of transport of chemical logistics. From the absolute amount of energy consumption, the energy consumption of rail transport is huge, so it is the key sectors of energy conservation. Then the optimization model of energy conservation strategies is established, considering the line type, blocking the way, the running time for the interval, the station operat- ing time, interval velocity, station interval and the interval to be bound train track. Finally, numerical examples are verified. The re- suits show that when using this program optimization, a slight increase in the basis of＂ the train running time, greatly reducing the overall operating costs, get a good energy conservation effect.
