摘要:
针对城轨供电系统采用平铺运行图进行负荷过程仿真分析与实际负荷过程差别大，不能准确反应供电系统运营阶段的诸多问题，将运行图中各列车运行时分作为约束条件，建立列车定时节能运行的指标函数，以提高仿真模型准确性；基于固定阶梯级目标速度搜索算法优化列车操纵序列，还原多列车具有电气信息的运行轨迹；以实迹运行图为驱动，实现了供电系统正常运行与异常情形下的负荷过程仿真分析. 算例分析结果表明：基于实迹运行图的仿真结果与实测牵引变电所负荷过程曲线的Pearson相关系数在0.89以上，负荷过程特征值仿真与实测的最大误差不超过6.85%，较平铺运行图仿真结果准确度最高可提升12.91%.
Abstract:Load process simulation analysis based on the paving operation diagram for urban rail power supply system is significantly different from the actual load process, which cannot accurately reveal many issues in the operation stage of the power supply system. To improve the accuracy of the simulation model, with the train running time in operation diagram as constraints, the objective function with respect to the scheduled energy-saving train operation is established. The target velocity search algorithm with a fixed step is used to optimize the train control sequence and restore the electrical information of the operation diagram with multiple trains. Driven by the actual operation diagram, the load process simulation analysis of the power supply system is performed under normal and abnormal operations. The case study shows that the Pearson correlation coefficient between the simulation results from the actual-track operation diagram and the measured load process curve from traction substations is above 0.89, and the maximum error between the simulated and measured characteristic values in load process is not more than 6.85%, which can improve the accuracy of the simulation results by 12.91% in comparison to the tiled operation diagram.
