列车牵引能耗计算方法

Calculation Method of Energy Consumption in Train Traction

针对列车牵引能耗既有计算方法缺乏统计标准和能耗预测手段,通过分析机车性能、线路属性等因素对列车牵引能耗的影响,提出新的能耗计算方法。算法步骤是:客车按照车次、货车按照机车交路确定列车运行经路;按照列车起停、运行、惰行及空转、出入段及调车、上坡5种牵引过程,分别计算各区段的列车牵引能耗;按照列车径路累加各区段的能耗值,并换算为油、电的消耗量,最终计算出能耗费用。据此开发列车牵引能耗计算软件系统,以宝成线、丰台机务段为例进行能耗计算及影响因素分析,以DJ4和SSJ3为例进行新型机车牵引能耗的预测。结果表明,应用此计算方法和系统能够及时掌握列车牵引能耗的变化。

Because there are no statistics standard and forecast measure in existing calculation method for energy consumption of train traction, a new method to calculate the energy consumption of train traction is put forward by analyzing the impact on the energy consumption of train traction by such factors as locomo- tive performance and railway line attribute, etc. The calculating steps are listed as follows. The transportation route of passenger train is chosen according to train number and that of freight transportation according to locomotive routing. The train traction energy consumption of every section is calculated by five traction processes including train starting ＆ stopping, running, coasting ＆ idling, leaving ＆ arriving at the depot, and shunting. Then the energy value of each section is accumulated according to the train route, and the sum energy is conversed to the quantity of diesel oil or electricity, and the cost is computed. Based on this, calculating software of train traction energy consumption is compiled, by which can calculate and forecast the quantity of traction energy consumption. Taking Baocheng line and Fengtai locomotive depot, DJ4 and SSJ3 as examples, calculation of energy consumption and analysis of affecting factors, prediction of energy consumption in train traction for new-type locomotives are carried out. Results show that this calculation method and system can master in time the change of energy consumption in train traction.
