The Apriori is an algorithm about the generation of association rule. Enlightened by the generation of candidate k-itemsets, k subsets of one item will be first find out, and then connected to get subsets of two items, and finally get the subsets of k-1 items. The algorithm can be used to find out the proper subset and to generate the protasis and apodosis of the association rule.

Usually, distribution networks operate in arborescence mode, so in the simulation of fault analysis the impact of faulty switch element on system reliability is apportioned to failure consequences of adjacent sections that connect to switch, and then an equivalent analytical model considering switch fault is proposed. Thus, not having to conduct the reliability analysis of switch element singly, the impact of switch element fault on system reliability can be calculated. Applying the proposed algorithm in RBTS-BDS6 system, RBTS-BUS4 system and actual medium-voltage distribution network to conduct reliability assessment, the results show that the proposed algorithm is superior in speed and possesses efficiency and engineering practicality.
