基于监测数据的智能变电站遥控信息故障诊断方法研究

Research on the Fault Diagnosis Method of Remote-Control Information of IntelligentSubstation Based on Monitoring Data

智能变电站采用先进的电子传感器技术,以高速通信网络的方式实现二次设备间的信息共享,取代了传统物理光纤通信的方式。当站内出现继电保护遥控信号逻辑控制故障时,难以确定故障原因及具体故障位置,对此提出一种基于监测数据的智能变电站遥控信息故障诊断方法,通过建立遥控信息通信链路数据模型,预置各节点数据,同时采集遥控信息通信链路中各节点实际数据值,根据两者数据差异情况实现遥控信息故障诊断定位。

The intelligent substation adopts advanced electronic sensor technology to realize the information sharing between secondary equipment in the form of a high-speed communication network,replacing the traditional physical optical fiber communication.When there is a fault in the logic control of the relay protection remote control signal in the station,it is difficult to determine the cause of the fault and the specific fault location.In this regard,a fault diagnosis method of remote-control information of intelligent substation based on monitoring data is proposed.By establishing the remote-control information communication link data model,the data of each node is preset.At the same time,the actual data values of each node in the remote control information communication link are collected,and the remote control information fault diagnosis and positioning is realized according to the difference between the two data.
