摘要
研究了一种货运列车节能优化方法。首先以列车运行时间为约束,建立列车节能运行优化模型。设计了一种基于极大值原理的动态规划算法,在满足运行时间约束下,实现列车最优节能运行操纵策略优化。本算法仅仅对速度进行离散化处理,相比其他方法需对位置和速度进行双重离散,避免因网格划分引起的速度轨迹波动,同时提高了计算效率。此外,该算法将考虑电分相对操纵的限制,便于工程应用。最后,利用HXD1型电力机车牵引的货运列车与朔黄铁路西柏坡至肃宁段验证了文中所述的优化方法的有效性。
An energy-saving optimization method of freight train was studied.Firstly,the interval running time constraint is introduced,so that the energy-saving operation optimization model was built.Then,A dynamic programming algorithm based on the analysis conclusion of maximum value principle is designed to optimize the train operation control strategy and timetabling synchronously.For this algorithm,only the velocity is discretized,which effectively avoids the velocity trajectory fluctuation caused by the discretization of position and velocity according to the other dynamic programming method.In addition,the proposed algorithm took the neutral zone into account which could be more suitable in engineering.Finally,a simulation with the freight train drew by HXD1 locomotive running on the Xibaipo to Suning section of Shuohuang line indicates the proposed method effectiveness.
