Power grid operation scene dynamic judgment method and system

The invention discloses a power grid operation scene dynamic judgment method and system, and the method comprises the steps: obtaining the operation multivariate basic information of a to-be-detectedpower grid, inputting the operation multivariate basic information to a pre-built scene mode library for matching judgment, and outputting a dynamic operation scene if the operation multivariate basicinformation is completely matched; and if the similarity is matched, performing association rule updating and data updating on a pre-constructed scene mode library by utilizing the input power grid operation multivariate basic information to be tested to obtain a new scene mode library, and if the similarity is not matched completely, determining a new association rule by utilizing a predefined rule of a power grid dispatching control system, and adding the new association rule into the scene mode library. The method and the system provided by the invention have the advantages that the scenecan be intelligently judged
