当今节能减排、低碳发展已成为地铁交通网络化综合化发展的重中之重。着眼于再生制动技术在多列车节能运行过程中日益突出的效用,将如何提高多列车运行的再生制动能量利用率作为研究重点,利用地铁列车发车间隔与停站时间的可控性,提出一种基于再生制动的地铁多列车节能运行策略模型,并给出一种有效求解此类问题的算法以及设计出一种解析解方程可快速求解此类问题。最后以北京地铁线路亦庄线为例,验证优化模型的可靠性与算法的高效性。结果表明:在保证该线14站13区间列车准点运行的情况下,采用多列车节能运行策略优化模型后,列车平均再生制动能量利用率提高0.15左右,运行总能耗降低5.01%。将本文的研究成果应用于平峰期间多列车节能运行上具有一定的指导意义。
Energy efficiency emission reduction and low carbon development have become a top priority in the development of urban rail transit nowadays.With a view to the increasingly prominent role of regenerative braking technology in energy-saving operation of trains,this paper proposed an energy-efficient operation strategy of trains based on the regenerative braking for urban rail transit to optimize the controllability of train headway and dwelling time and to increase the use ratio of regenerative braking energy.An effective algorithm to solve such problems was given and a set of analytical solution equations was designed to obtain the solution quickly.Finally,a case study of Yizhuang urban rail line in Beijing was conducted to verify the reliability of the proposed model and the efficiency of the algorithm.The results showed that the total energy consumption was reduced by 5.01 percent and the average utilization ratio of regenerative braking energy was increased by 0.15 with this optimization model in the condition of that keep trains on-schedule running in the line.The research result,which is applied to the energy-saving operation of trains in non-rush hours,has a guiding significance.
