摘要
动车组能耗评估对于列车顶层参数设计、新建线路能耗评估等工作意义重大,其关键在于动车组能耗的准确测算。文中采用基于牵引效率曲线的能耗计算方式进行仿真计算。根据实测动车组牵引效率曲线,总结不同级位下牵引效率特点,并将其作为能耗测算的输入条件,建立能耗计算模型进行仿真计算。将能耗仿真计算结果与实际线路测试的能耗数据进行对比分析,误差在2.4%~7.3%之间,验证了该能耗仿真计算模型及方法的实用性和准确性。
The assessment of energy consumption for China Railway High-speed Train has great significance for design of top-level parameters and energy consumption evaluation of newly-built railway.The key is to calculate the energy consumption of high-speed train accurately.In this research,energy consumption is computed by simulation based on traction efficiency curve.According to measured traction efficiency curve of high-speed train,the features of traction efficiency in different power grades are summarized.As input conditions,these features are applied to build calculate model of energy consumption.The results of energy consumption between simulation and on-site test data are analyzed and contrasted.The contrast results indicate that the error is from 2.4%to 7.3%,which verify practicability and accuracy of mathematical model and simulation methods of energy consumption.
