Description

technical field

[0001] The invention relates to a method and device for automatically generating a geographic wiring diagram of a power grid, and belongs to the technical field of power grid equipment management and operation and maintenance information technology. Background technique

[0002] Geographic wiring diagram is a basic graphic commonly used in distribution network operation and maintenance management. It has a wide range of application scenarios in the visualization of power outage information, auxiliary formulation of business expansion and installation plans, emergency repairs, and life cycle management of power assets.

[0003] At present, the relevant research on the automatic generation technology of the grid geographic wiring diagram is very limited. The maintenance of the grid geographic wiring diagram of the State Grid Corporation of China is still based on manual drawing. This method is slow in efficiency and the drawing accuracy is uncontrollable. The e...
