The invention relates to the technical field of data processing, in particular to a smart power grid abnormal operation state detection method and system, and the method comprises the steps: collecting power grid power data; obtaining the possibility that the (i + 1) th power grid power data belongs to the right neighborhood interval of the ith power grid power data, and obtaining the right neighborhood interval of the ith power grid power data; obtaining the possibility that the (i-1) th power grid power data belongs to the left neighborhood interval of the ith power grid power data, and obtaining the left neighborhood interval of the ith power grid power data; acquiring a neighborhood interval of the ith power grid power data; the similarity between the neighborhood interval of each power grid power data and the neighborhood interval of the adjacent next power grid power data is obtained, then the updated neighborhood interval of each power grid power data is obtained, the number of neighborhoods of each po
