【摘要】 随着电气化铁路的比重增加，对系统各组成部分及其相互关系的研究提出了更高的要求。因而，如何合理而有充分依据地进行电气化铁路的新线设计，科学地组织现有电气化铁路的运行及改造，以及正确选择与评价牵引供电系统供电设备的能力，评价电气化铁路供电系统对电力系统的影响等，从而实现合理、经济和可靠地多目标规划，是电气化铁路所面临的重大问题。本论文以计算机仿真为手段，以最小能耗为目的，建立了分析电牵引负荷运行过程的计算机仿真模型，较为全面地考虑了各种对负荷过程有影响的因素，较真实地再现了电牵引负荷的动态过程，同时分析了对不同类型电力机车以最小能耗为原则的列车合理操纵系统，为牵引运行仿真提供机车操纵标准。另外，利用MATLAB软件平台上的仿真软件SIMULINK建立了韶山4改进型电力机车数字仿真模型，并利用SIMPOERSYSTEM工具箱的POWERGUI对电流进行FFT分析，得到注入牵引网的基波和各次谐波电流的幅值和含量，为计算牵引变电所全天24h谐波电流的随机模拟计算打下了基础。更多还原

【Abstract】 With the proportion of electric railways increasing, higher requirements to the research about each part of systems and their correlations are put forward. Thus, an important problem that electric railways face to is how to design the electric railways function and their reconstruction reasonably and sufficiently, and organize them scientifically, and how to select correctly and value the ability of the traction power system equipments, evaluate the influence of power systems which electric railways bring to, thus realize reasonable, economical and reliable multi-goal programming.In this paper, by the means of computer simulation, with a minimum of traction energy consumption a simulation model, which analyse electric locomotives and load-process in AC traction system is designed. This model better completely think of all possible kinds of effects, which can effect the processing of traction load, it can better truly reflect the dynamic process of electric locomotives. At the same time, an optimum train control algorithm ensuring train operation with a minimum of traction energy consumption is builded. It provides the standard how to operate the train for the traction simulation. In addition this paper builds the digital model of SS4 with the simulation software SIMPOWERSYSTEM based on MATLAB. Through of current with FFT function POWERGUI. Fundamental and harmonic current injected into the catenaries by the electric locomotive is deducted.更多还原
