Association Rules-based Diagnosis of Vulnerabilities in Distribution Networks
During the operation of the distribution network,various faults often occur at the weak points of electrical e-quipment,which seriously affect reliability.Hence this paper proposes a distribution network vulnerability analysis and di-agnosis method based on undirected FP-network.First the basic concepts and practical applicative significance of the three judgment indicators of support,confidence and imbalance ratio in association rules are described.Then collection and colla-tion of distribution network vulnerability fault data are outlined,the fault data of subsequent correlation rules is prepro-cessed,and the distribution network vulnerability analysis model is established.Finally undirected FP-network is verified through case analysis feasible and accurate in diagnosing distribution network vulnerabilities with an accuracy of higher than 90%.
