Intelligent alarm method and system based on cooperative processing of polymorphic data

The invention provides an intelligent alarm method and system based on cooperative processing of polymorphic data. The method comprises the steps of collecting the polymorphic data of secondary equipment at a station end in real time through a direct collection and direct transmission mode, building an intelligent logic cooperative reasoning diagnosis module based on steady-state data and dynamic data according to the respective electrical characteristics of different data sources, and providing the result for operation and maintenance personnel as a basis for next operation and maintenance. The method provided by the invention can improve the operation monitoring method of the secondary equipment of the power grid, does not completely depend on the original alarm information of the secondary equipment, and provides an auxiliary monitoring measure. The method can quickly find abnormal operation of the power grid, reminds operation and maintenance personnel to solve problems in time, prevents further expansion
