城轨车辆ATO模式节能策略研究

Research on ATO Mode Energy Saving Strategy of Urban Rail Vehicles

通过计算牵引能耗、制动能耗、辅助能耗对城轨车辆电耗的影响程度可知,牵引能耗、制动能耗占研究样本中单车能耗的99.2%。因此降低城轨车辆能耗应从降低牵引和制动能耗入手,辅助以控制辅助能耗的节能策略。城轨车辆牵引、制动能耗主要发生在列车出站加速及进站减速过程中,以北京轨道交通昌平线为例,与市中心线相比,郊区线路站间距长,更适宜结合运行图排布及长大区间对列车ATO自动控制系统进行节能优化,达到节能减排的目的。

By calculating the impact of traction energy consumption,braking energy consumption,and auxiliary energy consumption on the power consumption of urban rail vehicles,it can be seen that traction energy consumption and braking energy consumption account for 99.2% of the single vehicle energy consumption in the research sample.Therefore,reducing energy consumption of urban rail vehicles should start with reducing traction and braking energy consumption,and assist in controlling auxiliary energy consumption through energy-saving strategies.The energy consumption of traction and braking of urban rail vehicles mainly occurs during the acceleration and deceleration process of trains at the exit and entry.Taking the Changping Line of Beijing Rail Transit as an example,compared with the city center line,the distance between stations on suburban lines is longer,making it more suitable to optimize the ATO automatic control system of trains based on the layout of train diagrams and long and long intervals,in order to achieve the goal of energy conservation and emission reduction.
