The Research on Development of EHV Line Longitudinal Protection Debugging Device in Intelligent Substation

Abstract:

In smart substation, transmission line longitudinal protection debugging cannot take place, before the line communication channels construction, that cause it often occur that not fully debug, choose a suitable time for debugging in advance. In this paper, based on the analysis of the longitudinal protection debugging process, combining with the computer technology, and 3G/4G communication technology, design a set of intelligent substation EHV-line longitudinal protection device of temporary channels. Ensure, in intelligent substation, carry out advanced debugging, select the appropriate time debugging, debugging completely, before the longitudinal channel built, and establish a reliable foundation for the normal operation of the longitudinal protection equipment.
