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 parameters of line, train operating conditions and timetable, the utilization of train regenerative braking energy in the same power supply section is analyzed, and a multi-car energy saving optimization model based on regenerative braking energy utilization and operation schedule design is established. The concentration immune algorithm is introduced to adjust train departure time, stop time and running time in the train timetable and optimize the train operation conditions to solve the energy saving operation schedule and multi-vehicle energy saving driving strategy under the actual route. According to the simulation data of a power supply section of Nanning Metro Line 1, it is proved that the utilization of regenerative braking energy is increased by 11.4% and the total energy consumption of the train operation is reduced by using the optimized energy-saving operation schedule under the premise of meeting the punctual operation 16.9%.
