Most of the equipment on-line monitoring system does not have the function of accident inversion or weak function. Even if it has the function of inversion, it only records the real-time steady-state information of a specific type within a period of time before and after the time of the accident, which cannot meet the actual needs of customers. This paper proposes a polymorphic accident inversion method based on time series database, equipment on-line monitoring of the site of all collected data by time sequence database for high-speed storage, reappear in the inversion environment equipment failure accident system before and after all of the conditions and for the whole process of continuous play, for the analysis of status evaluation for power grid provides a simulation environment of inversion and effective data to support. Based on the design idea of polymorphism, the user accident inversion requirements under different scenarios are satisfied.
