Abstract:In order to effectively meet the needs of association rules mining in smart grids, this study completed the construction of the FP-network model by inheriting the advantages of association tree mining frequent tree algorithm, and compressed the information to be mined on an undirected network graph. On the basis of this, the paper completed the construction of the transaction item association matrix, realized the data storage and mining process. It also introduced in detail the application process of the association rule mining algorithm model in the transmission line fault analysis. The mining algorithm only needs to scan the database once. The efficiency of mining association rules is significantly improved, and the model can effectively meet the needs of mining big data associations in smart grids.
