[0002] With the continuous expansion of the scale of power grids and the improvement of their intelligence level, geographic information systems (GIS) are playing an increasingly important role in power grid planning, construction, operation and management. GIS systems can provide geographic location information, power grid topology, equipment attributes and other data of power grid facilities, providing intuitive geographic information support for the operation and management of power grids.
