基于IEC61850的变电站测量设备故障检测

Fault Diagnosis of the Substation's Measurement Equipment Based on IEC 61850

在变电站自动化程度发展到以太网通信条件下,测量设备的故障检测也随之出现许多新的问题。以变电所测量设备检测为研究对象,以IEC61850标准中测量模型为研究基础,采用面向对象的新方法,将信息分为可以访问的逻辑信息组,逻辑信息组又进一步划分为不同的逻辑节点。每一个逻辑节点由代表一些特定功能的数据组成。用户可以研究和浏览这些逻辑节点,提取出所需的数据。根据电网的拓扑图实现测量设备的自检测和故障定位。

Many new problems of fault detection and diagnosis for measurement equipment have merged along with the development of the Ethernet used in substation communication systems.With the fault diagnosis and location in the substation as the research object and the measurement model of IEC 61850 as the groundwork,the information are split into information chunks,and then the information chunks are split into different logical nodes.Each logical node is composed of certain data which represent some specific functions.It is convenient for user to research and view these logical nodes,then retract the valuable information.According to electric power grid,the system can realize the fault diagnosis and location for measurement equipments.
