摘要
地铁列车牵引电力消耗总量过大是目前地铁运营公司面临的一大问题。为量化评估地铁列车牵引能耗,促进厂家不断优化牵引系统设计,降低地铁列车牵引能耗,文章在综合分析影响地铁列车牵引能耗因素的基础上,根据地铁列车牵引能耗测试的控车需求,研制了一种用于地铁列车牵引能耗测试的便携式控车装置,其实现了通过模拟司控器级位信号控制不同厂家地铁列车的自动运行和采集、记录和分析地铁列车牵引能耗数据的目标。试验结果显示,该装置能保证试验过程中列车按照规划曲线运行的最大速度误差小于2 km/h,解决了因人工操纵造成的列车运行过程不一致、试验数据不可信的问题,可满足对不同厂家地铁列车进行牵引能耗测试时的控车需求。
Excessive total traction power consumption of metro train is a major problem faced by metro operation companies.In order to quantitatively evaluate traction energy consumption of subway trains, promote manufacturers to continuously optimize the design of traction system and reduce traction energy consumption of metro trains, this paper comprehensively analyzes the factors that affect energy consumption of subway trains, according to the vehicle control demand of traction energy consumption test of metro trains, a portable control device for traction energy consumption test is designed according to the requirements. Automatic operation of metro trains of different manufacturers is realized by simulating level signal of driver controller. Traction energy consumption data of metro trains is simultaneously collected and analyzed. Test result shows that the device can ensure that the maximum speed error of the trains which running according to the planned curves during the test is less than 2 km/h, solve the problems of inconsistent operation process and unreliable test data caused by manual operation of trains, and can meet the vehicle control requirements for traction energy consumption test of metro trains from different manufacturers.
