北京市轨道交通列车运行节能控制方案研究与应用

Research and Application of Energy Conservation Program for Train Operation Control of Beijing Rail Transit

城市轨道交通线路由于站间距较短,在运行过程中列车启动、制动频繁,能耗较大,造成资源浪费和成本增加。通过对北京轨道交通线路实际能耗和运营情况统计分析,从列车运行控制策略及运行图合理适配的角度出发,提出单车ATO节能、多车ATS与ATO联动节能、ATS-ATO自适应节能3种列车运行节能控制方案及分阶段递进实施的重点。目前正在改造或试验的线路数据表明,利用在站间增加列车惰行距离,减少不必要的牵引制动切换,提升坡道、弯道智能预判,科学设计ATS与ATO系统配合关系等策略,可以有效降低牵引能耗和运营成本,试验后可在北京轨道线网中推广应用。

Due to the short distances between the stations of urban rail transit lines, the trains start and brake frequently during their operation, resulting in large energy consumption, waste of resources, and increased costs. Through statistical analysis of the actual energy consumption and operation status of Beijing rail transit lines, this paper approached from the perspective of properly adapting strategies of train operation control and the train timetable and put forward three energy conservation programs for train operation control and the stage-by-stage progressive implementation focus. The three programs are respectively energy conservation based on automatic train operation(ATO) of a single train, energy conservation based on automatic train supervision(ATS) and ATO linkage of multiple trains, and self-adaptive ATSATO energy conservation. According to the data from the lines currently under transformation or testing, traction energy consumption and operation costs can be effectively lowered by increasing the coasting distances between stations for the trains, reducing unnecessary traction and braking switches, improving the intelligent prediction of ramps and curves, and scientifically designing the cooperation relationship between ATS and ATO subsystems. The proposed program can be applied to the Beijing rail transit network after testing.
