城市轨道交通运行图优化节能方案研究

摘要地铁具有运量大、定时、安全、环保等优点，但总能耗仍然巨大，因此研究地铁的节能方法非要重要。地铁列车的再生制动能量按一定比例被相邻列车利用，剩余部分被列车或线路上的吸收电阻以热的形式消耗掉。合理调整时刻表就是合理调整线路上列车的启动、制动情况，可使尽可能多的再生制动能量流向需要能量的车辆，节约总能耗。
本论文采用遗传算法，以南京地铁一号线为例对地铁时刻表中车辆停站时间优化减少总能耗进行研究。首先分析南京地铁及其供电系统；在此基础上以减少总能耗为目的，采用实数编码的遗传算法对地铁时刻表中停站时间优化；最后分析其优化效果。仿真结果表明采用实数编码的遗传算法优化地铁时刻表可以显著地减少地铁列车总能耗。9394

Title   the study of timetable optimization for energy saving in urban rail transit
Abstract
Subway features large volume, timing, safety, environmental protection, etc. However, its total energy consumption is very large. Therefore, it is important to study the energy saving method of subway. Regenerative braking energy is used by adjacent train according to a certain proportion, and the rest is absorbed on the train resistance or line resistance in the form of heat. Careful train scheduling can adjust train's starting and braking, make much more regenerative braking energy flows to the train in need of energy, save energy.
This paper employs genetic algorithms to optimize train scheduling and use the Nanjing Metro as an example. First analyzing Nanjing Metro and its power supply system. Then using real-coded genetic algorithm to optimize the dwell time for the purpose of reducing energy consumption of all trains. Finally analyzing the optimization effect. Simulation results show that the proposed method can significantly reduce the energy consumption of all trains.
Keywords Electrical railway system    Genetic algorithms    dwell time    Timetable    optimization and energy saving
