同相贯通供电方案灵活备用方式可靠性分析

摘要

Taking the single phase combined co-phase system as an example, the GO diagrams of three traction substations with different standby mods were established in this paper on the basis of the principle of the GO methodology. Corresponding programs were written on the MATLAB platform, and results of the reliability were obtained. Compared the results with traditional co-phase power supply system, conclusions can be drawn that co-phase continuous power supply system with different standby modes has higher reliability and has more choices in standby modes. Moreover, it can save more equipments.%基于GO法基本原理,以单相组合式同相供电接线方式为例,对3种不同备用方式的牵引变电所建立GO图,利用MATLAB平台,编写GO计算程序,计算相关参数,得出3类牵引变电所可靠性分析结果,并在此基础上分析整个同相贯通供电方案的可靠性并与传统同相供电方案进行比较,结果表明前者可靠性优于后者,且在备用方式上有更多选择,亦可以节约更多设备.
