Timetable Design of Metro Train Based on Regenerative Braking Energy Utilization

结合线路参数、列车运行工况以及时刻表等因素,分析了同一供电区段内列车再生制动能量的利用情况,建立基于再生制动能量利用与运行时刻表设计的多车节能优化模型。通过引入浓度免疫算法,调整列车时刻表中发车间隔、停站时间、运行时间等要素并优化列车操纵工况,求解出实际线路下的节能运行时刻表及多车节能驾驶策略。结合南宁地铁1号线某供电区段的仿真数据证明,采用优化的节能运行时刻表在满足正点运行的前提下,提高再生制动能量的利用率达11.4%,降低列车运行的总能耗达16.9%。

Combined with the line parameters, running condition, operation schedule, and so on, tiae recovery ana utilization of regeneration braking energy was analyzed in the same power supply section. The multiple vehicles energy-saving optimization model was built based on the use of regenerative braking energy and the design of timetable. By introducing the immune algorithm, the headway, dwell time and running time were adjusted, and the train operation strategies was optimized. Finally, the energy-saving train operation schedule and multi vehicle energy-saving driving strategy were obtained in the actual line. The simulation data of one power supply section of Nanning metro line 1 proved that the utilization rate of regenerative braking energy was improved up to 11.4% and the total energy consumption of train was reduced up to 16.9% by using the optimized energy-saving schedules, which ensured the punctuality.
