摘要随着城市的发展,轨道交通系统对于人们的生活越来越重要,而供电系统又是轨道交通系统中最为重要的一部分。本文对南京地铁的牵引供电系统进行了较为全面的研究。相对于电网中的其它负荷来说,地铁负荷具有其特殊性,主要因为地铁负荷随时间变化会出现较大的波动性。本论文分别对地铁的牵引供电变电所和车辆进行建模。接着介绍了使用软件对地铁牵引供电系统建模的方法,并使用C++对牵引供电系统进行仿真计算。得出的结果很好的符合了实际的运行情况。最后,根据对研究问题的理解对本文的研究工作进行总结。9538

Title The Research on simulation of DC traction power
supply system of urban rail transit
Abstract
With the development of the city, rail transit system is more and more important for people's lives, while the power supply system is the most important part of the rail transportation. Traction power supply system of Nanjing metro is thoroughly studied in the dissertation. Comparing to other load kinds, metro load has its special characteristic, mainly because metro load becomes very fluctuant as time pass by. In this paper, the metro traction power substations and vehicles are modeling respectively. Then introduce the use of the software on the subway traction power supply system modeling, and use the C++ to simulate and calculate the traction power supply system. The results fit well with the actual operation. Finally, according to the understanding of the research problems, a summary of this dissertation was concluded.
