Research on Mobile Terminal Technology Supporting Intelligent Maintenance of Substation

In view of the fact that traditional substation maintenance operations need to carry a large amount of paper data and the on-site paperlessness is low, a mobile terminal supporting intelligent maintenance of substations has been developed. Introduce the development background, system integration scheme, various management functions of the device and its application in substation maintenance operations, recorder viewing and grid fault analysis. The application of the mobile terminal can improve the intelligence level and convenience of on-site maintenance operations, shorten maintenance time, improve maintenance quality, and improve the level of relay protection lean management.
