摘要
在对国内外铁路机车能耗模型进行分析的基础上,以我国传统铁路客贷共线运行列车为研究对象,从机车能耗产生的微观角度出发,运用列车运行计算的相关原理,设定了列车运行环境,建立铁路机车单耗测算模型。模型中引入"牵引运行能耗换算系数",通过微观数值计算方法测算机车单耗的宏观量,计算机车担当客、货运时的单位能耗值。根据机车数量比例和完成的运输工作量,通过加权平均法测算机车综合单耗。经过测算,内燃机车综合单位耗油量与电力机车综合单位耗电量的模型测算值与实际统计值较为吻合。
Based on analyzing the energy consumption model of railway locomotive in China and abroad,taking transitional trains on mixed transport of freight and passenger line,beginning from microcosmic view of locomotive energy consumption,train operation environment was settled and energy consumption model of railway locomotive was established by using relative principles of train operation calculation.The conversion coefficient of energy consumption for traction has been taken into the model to calculate the macroscopic locomotive energy consumption though microscopic numerical calculation method.The model could be used for calculating energy consumption of both passenger trains and freight trains.Unit comprehensive energy consumption of locomotive is calculated by using weighted average method according to locomotive proportion and transportation workload.Through calculating, the fuel consumption value of diesel locomotive and the electric consumption value of electric locomotive are close to actual statistics data.
