摘要
通过对动车组能耗的各种影响因素的分析,按照动车组运行过程的起停、运行、调速制动、出入库等环节,针对每一环节分别研究其能耗计算方法,考虑坡道附加能耗和空调能耗,分别建立数学模型、确定修正系数。研究提供的动车组能耗计算方法可以进行能耗计算与预测,以及对能耗影响因素进行分析。以广深客运专线为例,动车组能耗计算结果与实际能耗的拟合性好,可以为合理确定既有线和客运专线动车组能耗水平提供帮助。
By analyzing all the factors that influence the EMU energy consumption,the energy consumption calculation method for all the steps including starting,running,braking,in/out the yard is studied,considering additional consumption for slope sections and air conditioning system.The simulation model is established and the correction factor is determined.Energy consumption calculation and prediction can be done based on this model and the influence factors can be analyzed.The case study is based on Guangzhou-Shenzhen PDL,on which line the calculation result is quite close to the actual energy consumption.This study will be useful to the determination of EMU energy consumption level on existing lines and PDLs.
