AI Technical Summary

Technical Problem

During the power distribution process, the process of operators searching for the relay protection settings of the corresponding switches in the system is cumbersome, resulting in low verification efficiency.

Method used

By using a distribution network GIS system, the core settings of the relay protection of distribution network lines are obtained and drawn into a simplified GIS single-line diagram. The current settings and primary values ​​of each component are marked to form a distribution network relay protection setting coordination diagram, thereby achieving centralized and unified management.

Benefits of technology

It improves the ability of operators to quickly, accurately, and efficiently verify protection settings in the event of a fault, reduces the tediousness and errors in the verification process, and improves verification efficiency.

Abstract

The application relates to the technical field of distribution network relay protection, in particular to a relay protection core fixed value management method based on a distribution network GIS system, which can solve the problem that the process of operation personnel sequentially searching for the relay protection fixed value of corresponding switches in the system is relatively complicated. The method comprises the following steps: obtaining relay protection core fixed values of a distribution network line; obtaining primary values of current fixed values corresponding to each component of the distribution network line, wherein the primary values of the current fixed values of each component are obtained by converting secondary values based on relay protection core current fixed values of the distribution network line; drawing a GIS single-line sketch of the distribution network line, wherein the GIS single-line sketch of the distribution network line is obtained based on a GIS single-line diagram of the distribution network line; and marking the primary values of the current fixed values corresponding to each component of the distribution network line into the GIS single-line sketch of the distribution network line to form a distribution network relay protection fixed value matching diagram.
