摘要:

分析城市轨道交通接触网系统发热原理及能耗情况，总结接触网能耗计算的基本方法和影响接触网能耗的主要因素，提出基于列车运行调整的改善触网电压、降低触网能耗的优化策略.进而以触网焦耳能耗最小为目标，考虑列车运行图和牵引特性等多重约束条件，运用蚁群算法，对基于无线通信列车自动控制原理的列车运行建立优化调整控制模型.最后根据上海地铁2号线一期实际参数进行仿真实验，验证优化策略的有效性和可行性.该策略对于计划运行图的改进及列车运行安排的实时调整优化均具有一定的指导价值.

Abstract:

By analyzing the thermal principle and energy consumption of catenary system in urban mass transit, this paper summarizes the calculation methods and main influencing factors of the catenary energy consumption.The optimization strategy for improving voltage and reducing energy consumption of catenary is presented based on train operation regulation. And a model minimizing the Joule energy consumption of catenary at the most is built to optimize and regulate the train operation schedule based on communication based train control system(CBTC) with the ant colony optimization algorithm under multiple constraints.At last the optimization strategy has been simulated with the practical parameter of the urban mass transit line 2 in shanghai and its effectiveness and feasibility are verified．The proposed strategy has a guiding value for improving the contemplated schedule and real time optimal regulation of train operation arrangement.
