Relay protection core constant value management method based on distribution network GIS system

The invention relates to the technical field of distribution network relay protection, in particular to a relay protection core constant value management method based on a distribution network GIS system, and can solve the problem that the process that an operator sequentially searches relay protection constant values of corresponding switches in the system is relatively tedious to a certain extent. The method comprises the following steps: acquiring a relay protection core constant value of a distribution network line; obtaining a primary value of a current constant value corresponding to each component of the distribution network line, wherein the primary value of the current constant value of each component is obtained by converting a secondary value of a relay protection core current constant value of the distribution network line; drawing a GIS single line diagram of the distribution network line, wherein the GIS single line diagram of the distribution network line is obtained based ...
