Abstract:

In order to effectively deal with the emergency operation accident of power grid system failure caused by disasters, based on GIS technology and grid emergency management theory,  a classification system of power grid emergency situation plotting elements was put forward, the symbol system and configuration method of traditional GIS were expanded. Then a power grid emergency situation plotting for automatic generation of decision model based on path selection algorithm was studied. By  constructing the 500kV 3D digital system of a province, the auxiliary emergency module was realized on this platform. The feasibility and effectiveness of the power grid emergency situation plotting technology was verified by the emergency drill of historical data.

Key words: power grid emergency, geographic information system, decision model, situation plotting, symbolization
