In recent years, power grid accidents have occurred frequently and higher requirements been placed on their safety operation. current management in the world, there is an effective practice that uses a unified standard for structuring accident case database based database, conducts quantitative analysis to cope with risks. However, not management. Case-based reasoning (CBR) such process solves new problems solutions similar past problems. It works by matching problem historical cases order obtain or inspirations. process, if necessary, may be modified better adapt actual Based CBR method, this paper proposes how construct of operational accidents, provide data support risks knowledge services accurate grasping development dynamics making quick decisions rapidly response emergencies. First, it designs after considering following three aspects: features, features theory. Secondly, terms use proposed two-level search strategy, as well corresponding similarity calculation methods different feature attributes case. Finally, carried out demonstration verify model selecting four typical accidents. The strategy article could help China’s grids intelligent improve digitalization
