客运专线高速、高密度的运行方式对铁路供电提出了新的要求。本文在分析现有铁路供电方式和运行模式的基础上,采用最新的计算机控制和通信技术,提出了客运专线供电自动化系统的体系结构,提高了铁路供电的可靠性,缩短了故障处理的时间,达到了减员增效的目的。文章在对系统可靠性进行定性分析的基础上,采用故障树分析法和蒙特卡罗算法进行了定量分析,得到量化指标;同时,对客运专线供电系统中的专家系统和数据接口的统一进行了研究,对系统的设计、施工、安装调试和维护提出了新的要求。
The high speed and high density of passenger dedicated lines put forward new requirements on railway power supply. Based on the analysis of the current railway power supply mode and operation mode, the paper adopts the latest computer control and communication technology, puts forward the architecture of power supply automation system for passenger dedicated line, improves the reliability of railway power supply, shortens the time for fault handling, Reached the purpose of downsizing and efficiency. Based on the qualitative analysis of the system reliability, the article uses the fault tree analysis and the Monte Carlo algorithm to quantitatively analyze and get the quantitative indexes. At the same time, the unification of expert system and data interface in the power supply system of passenger dedicated line Research, the system design, construction, installation and commissioning and maintenance put forward new requirements.
