继电保护的二次回路故障状态实时监测分析

Real Time Monitoring and Analysis of Secondary Circuit Fault Status in Relay Protection

随着智能电网技术的不断发展,继电保护二次回路构成变得越来越复杂,处理的实时信息非常庞杂,这增加了故障概率。为了提高电网继电保护的可靠性,构建在线实时监测系统就显得格外重要。在线实时监测系统是一种用于对二次回路进行故障检测和分析的系统。通过该系统,可以深度挖掘核心报文数据,进而形成完善的二次回路故障预警及分析体系。该体系可以准确地判断二次回路中出现的故障类型和位置,并及时给出故障诊断和处理建议。

With the continuous development of smart grid technology,the composition of relay protection secondary loop becomes more and more complex,and the real-time information pro⁃cessed is very complex,which increases the chance of failure.In order to improve the reliabil⁃ity of power grid relay protection,it is particularly important to build an online real-time moni⁃toring system.Online real-time monitoring system is a system for fault detection and analysis of the secondary loop.Through this system,the core message data can be deeply mined,and then a perfect secondary loop fault early warning and analysis system can be formed.The system can accurately judge the type and location of faults in the secondary loop,and give suggestions for fault diagnosis and treatment in time.
