This paper using a formal method based on ontology, the thing of urban power grid emergency management plan involves concepts, relations, axiom elements such as definition, ontology-based on relational database storage scheme is put forward. Then, the digital plan query system is designed. Finally, the combination of an electric power company in a given area emergency management plans to illustrate the feasibility of the method.
