一起110kV智能变电站主变保护链路异常的分析

Analysis of 110 kV Intelligent Substation Main Transformer Protection Link Abnormal

本文以一起110 kV智能变电站主变保护链路异常为案例,根据装置异常现象的特点、装置运行性能,通过网络分析仪对异常设备进行数据抓包,从中分析各种异常信息,判断异常问题的性质,确定引起主变压器保护装置链路异常的原因,并最终加以解决。

In this paper,with example of 110 kV intelligent substation main transformer protection link abnormal according to the device characteristics of anomalies,device operating performance,through a network analyzer for abnormal equipment for data capture,the paper analyzes a variety of abnormal information,judge the nature of the abnormal problem,determined the causing of link abnormal of the main transformer protection device,and ultimately to be solved.
