基于再生制动的城轨列车停站时间节能优化研究

Research on Energy-Saving Dwelling Time Optimization of Urban Rail Train Based on Regenerative Braking

针对城市轨道交通列车群再生能量利用较低的问题,对列车时刻表中的停站时间进行优化可以有效提高列车再生能量利用。停站时间不对列车的区间行驶产生直接影响,但会间接影响列车群功率曲线重叠状态,进而影响再生能量的利用情况。以在北京地铁八通线上运行的两列车简化车群为例,采用遗传算法对停站时间进行优化,利用MATLAB进行仿真验证,结果显示,停站时间优化有效提高车群再生能量利用。

In order to solve the problem of low utilization of regenerative energy in urban rail train group,optimizing the stopping time in train schedule can effectively improve the utilization of regenerative energy.The stopping time has no direct effect on the running of trains in the interval,but it will indirectly affect the overlapping state of train group power curves,and then affect the utilization of renewable energy.Taking the simplified group of two trains running on Beijing metro Batong line as an example,the stopping time was optimized by genetic algorithm and simulated by MATLAB.
