摘　　要：随着重载铁路运量的逐年增多,其能耗问题日益突出,节能降耗迫在眉睫,并且货运电力机车的牵引能耗是铁路牵引供电系统能耗的主要部分。为降低能耗,文章研究了一种计及线路条件的重载铁路货运电力机车节能操纵方法。首先,文章基于牵引计算基本理论建立了货运电力机车在区间运行过程中的动态负荷模型;然后,在此基础上,研究了一种考虑线路条件和准点性的节能操纵方法;最后,文章仿真分析了优化前后的节能效果,仿真结果表明,优化后货运电力机车的牵引能耗减少5%,验证了所提节能操纵方法的可行性。With increasing traffic volumes on heavy-haul railways,the issue of energy consumption is becoming increasingly prom-inent,underscoring the urgent need to reduce energy consumption in the operation of these railways.Given that the traction of freight electric locomotives accounts for a significant portion of the energy supplied by the traction power supply systems,this paper proposes an energy-efficient control method for freight electric locomotives operating on heavy-haul railways,taking into account specific track conditions.Firstly,a dynamic load model was established to represent the operation of freight electric locomotives on railway sections based on the fundamental theory of traction calculations.Subsequent research explored an energy-efficient control method that considers both track conditions and punctuality requirements.Finally,simulations were conducted to assess the energy-saving effect by comparing energy consumption before and after optimization.The results reveal about 5%savings in energy consumption for the optimized locomo-tives,which verifies the effectiveness of the proposed energy-efficient control method.
