随着我国城市化进展的逐步加快，城市交通拥堵问题与城市空气污染问题日益严重，地铁系统因为其运量大、安全高效以及节能环保等特点得到了极大的发展。尽管地铁系统已经是陆地交通方式中最节能的交通运输方式，但是随着其运营里程的快速增长，地铁系统的能耗在爆发式增长且其总能耗已经很巨大，能耗增加不仅增加了运营单位的压力也对国家的节能减排策略带来影响。其中列车运行能耗在地铁系统能耗中占到了很重要的部分，因此如何对地铁列车运行能耗进行详细的分析与计算，对地铁系统能耗的优化有着重要的意义。
本文研究一个运行间隔内同一供电区间中列车数量及运行方向的动态特性影响下的地铁多列车运行能耗计算问题，本文首先对单列车动力学模型详细分析，给出了不同列车牵引策略下的单列车运行曲线的仿真方法，并结合列车牵引制动特性曲线对不同状态下的列车进行功率需求分析，并针对地铁牵引供电系统的特点，建立了地铁牵引供电系统各组成部分的电路基本等效模型。
然后利用地铁系统运行的动态时变特性将单列车运行场景构成动态多列车运行场景，并将相应的场景与地铁牵引供电系统等效模型相结合，充分考虑再生制动利用和牵引电网电压对制动过程影响，结合再生制动与电阻制动投入的切换机理，提出一种将列车动力学模型与牵引供电模型相结合的动态多列车运行场景能耗计算模型，并根据电路潮流计算方法给出一种基于高斯-赛德尔迭代法的模型求解算法，实现动态多列车运行场景下的能耗精准计算。
最后本文基于上述研究思路搭建一个面向动态多列车运行场景仿真与能耗计算分析的平台，通过仿真平台的列车运行能耗实例仿真与分析结果，表明了本论文所设计的动态多列车运行场景能耗计算方法与仿真平台，能够对一个运行间隔内同一供电区间所存在的所有列车运行场景进行了分析，并能从电力能耗角度出发实现列车运行能耗的精准计算，对于节能过程中列车操纵策略的选择和列车调度安排有着重要指导意义。
 

With the gradual acceleration of the progress of urbanization in China, the problem of urban traffic congestion and urban air pollution has become increasingly serious. The subway system has been greatly developed because of its large capacity, safety and efficiency, and energy conservation and environmental protection. Although the subway system is already the most energy-efficient mode of transportation in land transportation, with the rapid growth of its operating mileage, the energy consumption of the subway system is exploding and its total energy consumption is already huge. The increase in energy consumption has not only increased The pressure of operating units also has an impact on the country's energy conservation and emission reduction strategies. Among them, the energy consumption of train operation accounts for a very important part of the energy consumption of the subway system. Therefore, how to analyze and calculate the energy consumption of subway train operation in detail has important significance for the optimization of the energy consumption of the subway system.
This thesis studies the calculation of the energy consumption of multiple subway trains under the influence of the dynamic characteristics of the number of trains and the running direction in the same power supply interval within a running interval. This paper first analyzes the dynamic model of a single train in detail, and gives the results of different train traction strategies. The simulation method of single train running curve, combined with the traction braking characteristic curve of the train to analyze the power requirements of trains in different states, and based on the characteristics of the subway traction power supply system, the basic circuit of each component of the subway traction power supply system was established, etc. Effect model.
Then, the dynamic time-varying characteristics of the subway system operation are used to discrete the single train operation scene into a dynamic multi-train operation scene, and the corresponding scene is combined with the equivalent model of the subway traction power supply system to fully consider the use of regenerative braking and traction grid voltage. The impact of the braking process, combined with the switching mechanism of regenerative braking and resistance braking inputs, proposes a dynamic multi-train operation scenario energy consumption calculation model that combines the train dynamics model and the traction power supply model, and gives the circuit power flow calculation method to A model solving algorithm based on Gauss-Seidel iterative method is developed to achieve accurate energy consumption calculation under dynamic multi-train operation scenarios.
Finally, based on the above research ideas, this article builds a dynamic energy consumption simulation calculation and analysis platform for dynamic multi-train operation scenarios. The simulation and analysis of the train operation energy consumption simulation examples on the simulation platform demonstrates that the dynamic multi-train operation scenarios designed in this thesis can The energy consumption calculation method and simulation platform can analyze all the train operation scenarios existing in the same power supply interval within an operation interval, and can realize the accurate calculation of train operation energy consumption from the perspective of power energy consumption. The choice of manipulation strategy and train scheduling have important guiding significance.
