摘要
首先分析了货运列车在平坡和变坡点处的计算方法,以降低货运列车牵引能耗为目标,时间和限速为约束条件搭建了货运列车节能优化模型。考虑线路中存在临时限速的情形,提出了一种基于不同区间划分的节能策略。此策略依据最快速度曲线下的工况序列对区间进行划分,在区间中插入惰行工况形成节能工况序列,利用改进鲸鱼优化算法求解各区间工况转换点的位置。最后通过在仿真和实际线路上与经典的四阶段节能策略进行对比分析,验证了所提节能策略的有效性。
Firstly, the calculation methods of freight trains at the flat slope and variable slope points are analyzed. Aiming at reducing the traction energy consumption of freight trains, an energy-saving optimization model of freight trains is established with time and speed limit as constraints. Considering the existence of temporary speed limit in the line, an energy-saving strategy based on different interval division is proposed, which divides the interval according to the working condition sequence under the fastest speed curve, inserts the idling working condition into the interval to form the energy-saving condition sequence, and use the improved whale optimization algorithm to solve the position of the condition conversion point in each interval. Finally, the effectiveness of the proposed energy-saving strategy is verified by comparing it with the classical four stage energy-saving strategy in simulation and actual lines.
