摘　　要：基于高速列车必须过电分相的特征,将整个列车运行区段划分为3类子区间,构建考虑过电分相的高速列车节能操纵优化模型。按照4阶段节能策略设计2种求解算法:司机常规操纵仿真算法和具有双层编码的节能操纵遗传算法。通过对2个实际案例和1个仅随机增大了实际案例坡度且坡长等其它所有线路参数与实际案例不变的虚拟算例验证,结果表明:所设计的节能操纵方法能够获得电分相存在时的不同线路的列车最优节能运行轨迹;当线路坡度起伏较小时,司机常规操纵仿真算法已是1种最为节能的方法;当线路坡度起伏较大时,节能操纵算法的优化效果明显优于司机常规操纵仿真算法,节能率超过5%;相比电分相设在加速区和减速区,电分相设在恒速区最为节能。Given the feature that high-speed trains must pass neutrally phase insulators,the entire train operation section is divided into three sub-sections,and an energy-saving operation model for high-speed trains is constructed considering passing neutrally phase insulators.Based on the four-stage energy-saving strategy,two algorithms are designed:driver routine operating simulation algorithm and energy-saving operating genetic algorithm with double-layer coding.The algorithms are verified by solving two actual cases and a virtual case with random increase in actual case slope and slope length and all other line parameters unchanged from the actual cases.Results show that the designed energy-saving operation method can obtain the optimal energy-saving operation trajectory of trains on different lines with the presence of the phase insulator.When the fluctuation of line slope is relatively small,the driver routine operating simulation algorithm is already the most energy-saving method.However,when the fluctuation of line slope is greater,the optimization effect of the energy-saving algorithm is obviously better than that of the driver routine operating simulation algorithm,and the energy saving rate exceeds 5%.Compared with the way to set the phase insulator in the acceleration zone or the deceleration zone,it is more energy-saving to set the phase insulator in the constant speed zone.
