智能变电站继电保护风险点分析

Risk Point Analysis of Relay Protection in Intelligent Substation

近年来,大量智能变电站投入运行,而新技术的应用给继电保护带来了一些新风险。因此,对智能变电站继电保护信息传递模式进行研究,分析智能变电站站内信息交互途径,阐述途径内存在的风险点,有助于运检人员针对重要风险点进行关键点把控,从而提高继电保护运行可靠性,保障电网安全可靠运行。

In recent years,a large number of intelligent substations have been put into operation,and the application of new technologies has brought some new risks to relay protection. Therefore,the study of relay protection information transmission mode in smart substation,the analysis of information exchange channels in Smart Substation and the elaboration of risk points in the channels are helpful for operators to control key points for important risk points,so as to improve the reliability of relay protection operation and ensure the safe and reliable operation of power grid.
