随着我国高速铁路运营里程的增加,高速列车牵引能耗也在快速增长,研究列车节能操纵具有必要的现实意义。本文结合高速铁路列车的运行特点和司机节能操纵经验,建立了定时约束下的高速铁路列车节能操纵优化模型,模型考虑了惰行过电分相等约束。同时,针对列车操纵特点,设计牵引惰行对操纵策略及相应的遗传算法。武汉至咸宁的仿真结果表明本文模型可在总运行时分不变的情况下降低9.8%牵引能耗。
With the increase of high-speed railway mileage in our country, the traction energy consumption of high-speed trains is also rapidly increasing. It is necessary to study the energy-saving operation of trains. In this paper, based on the operation characteristics of high-speed railway trains and drivers’ experience of energy-saving operation, a model of energy-saving operation optimization for high-speed railway trains with time constraints is established. The model takes into account constraints such as over- At the same time, according to the characteristics of train operation, the design of towing idiocy to maneuver strategy and the corresponding genetic algorithm. The simulation results from Wuhan to Xianning show that this model can reduce the traction energy consumption by 9.8% under the condition of the same operation time.
