基于举证表的智能变电站过程层通道故障定位方法

Proof Table Based Fault Location Method for Process Level Channel in Smart Substations

在二次系统物理回路模型的基础上,提出一种基于举证表的智能变电站过程层网络节点故障定位的方法。此方法通过从智能变电站配置文件中获取装置过程层通信的虚回路和物理端口信息,采用拓扑搜索方法得到通信链路对应的通道节点集合,建立过程层通道故障举证表并采集过程层通信状态为故障点举证,并根据多方举证结果定位通道故障点。

According to the physical circuit model of secondary system in smart substations,this paper proposes a fault location approach is proposed for process level networks based on the proof table.In the approach,information on virtual circuits and physical ports of process level communication is obtained from substation configuration description （SCD） files on smart substations,with sets of channel nodes associated with communication links obtained using topology searching.In addition,the fault proof table for process level channels is established to prove the fault points.According to multiple proof results of channel fault points detection,this approach can be used to locate the process level channel faults with smart substations.
