Zusammenfassung:The invention discloses an Apriori-based relay protection device fault determination method, and belongs to the technical field of relay protection device fault determination, and the method comprises the steps: obtaining frequent item sets of all types based on a pre-obtained alarm information data set; extracting a strong association rule from the frequent item set by using an improved Apriori algorithm; and extracting an association relationship between logic nodes in the strong association rule by using a DAM model, and obtaining component fault information of the relay protection device. According to the method, the association condition between the discrete alarm information of the transformer substation and the defective entity is mined through the improved Apriori algorithm, the logic nodes are further checked through the DAM model, and the defective equipment is locked, so that the intelligent level of relay protection device element fault diagnosis is improved; and the problems of large information
