变电站继电保护就地化整体解决方案研究

Research on Integrated Solution of Substation Relay Protection Localization

当前的智能变电站中经常使用合并单元以及智能终端进行传输,这种传输只是降低保护动作的速度,同时合并单元以及智能终端安装在户外的近地端,因此故障的发生率较高,不利于电网的安全运行。文章结合自身实践就二次设备的相关问题进行分析,提出智能化动作的保护以及配置方案,并重点就多间隔保护的相关问题进行分析,期望能够为变电站近地保护相关问题的解决提供借鉴。

Combined unit and intelligent terminal are often used for transmission in the current intelligent substation,but this transmission only reduces the speed of protection action.At the same time,the merging unit and intelligent terminal are only short near the outdoors,so the occurrence rate of the fault is high,which is not conducive to the safe operation of the power grid.In this paper,the author analyzes the problems related to the two equipment with its own practice,puts forward the protection and configuration scheme of the intelligent action,and focuses on the analysis of the related problems of the multi interval protection,hoping to analyze the related problems of the substation near ground protection.
