针对追踪运行地铁列车群,分析晚点情况下的常规“赶点”运行调整措施的缺陷,提出在晚点列车“赶点”运行调整措施的基础上,扩充后续列车的“延赶结合”运行调整策略:在晚点发生期间“延点”运行,以提高列车群分担时段客流的合理水平并挖掘节能运行的潜力;在晚点发生之后“赶点”运行,以消除前、后列车之间的晚点传播效应。基于此策略,后车ATO系统根据“追踪间隔”与“发到间隔”的双重均衡原则,以晚点时分的动态递增为依据,实时更新ATO模式曲线,并根据列车v-t实迹曲线的时序特征,动态调整牵引末速或制动初速,避免列车v-t实迹曲线与最优ATO模式曲线冲突,实现基于最优ATO模式曲线的实时的列车速度控制。根据牵引电机有功电流、列车牵引加速度及其变化趋势的综合作用对于列车能耗的决定性影响的分析可知:在牵引电机有功电流与列车牵引加速度分别相等条件下,与“正点”运行相比较,“延点”运行的节能量能够弥补“赶点”运行的费能量,实现列车能耗的总量节省。
Aiming at the tracing subway train fleet and analyzing the shortcomings of the conventional “rush hour” operation adjustment measures in the case of late arrival, the article proposes that the adjustment strategy of “late rush and combined operation” of subsequent trains should be expanded on the basis of the adjustment measures of “rush hour” : “Delay point” operation during the late period to improve the reasonable level of passenger flow in the train group sharing the time and tap the potential of energy-saving operation; and “catch-up” operation after late occurrence so as to eliminate the late-propagating effect between the front and rear trains . Based on this strategy, the ATO system of rear vehicle updates the ATO mode curve in real time based on the principle of “double interval between tracking interval” and “interval to send interval” based on the dynamic increment of late time point. According to the timing characteristics of real- Dynamically adjust the trailing speed or braking speed to avoid the real train speed control based on the optimal ATO mode curve by avoiding the collision between the train vt real trace curve and the optimal ATO mode curve. According to the analysis of the decisive influence of traction current and train traction acceleration and its changing tendency on the train energy consumption, it is found that when the active current of the traction motor and the train traction acceleration are equal respectively, compared with the “punctual” operation, Delay point “energy saving operation can make up for the” rush "operation fee energy, to achieve the total energy consumption of train savings.
