Abstract For the improvement of the operation speed and the fault-tolerant ability of the distribution network’s fault location, a new algorithm is proposed in this paper: Based on the chain table model, branch is taken for the unit to be used for the first location and searching the fault branch at the first. Then the data inconsistency between the head node and the end node could be used for the second location according to the link relation of the nodes in the fault branch; Local reconstruction is used to treat the nodes without data; The data correctness of each node is judged by the first location or the data relationship of the nodes in each furcation, on which some fault-tolerant mechanisms that could deal with one or more points fault and their correct rates are discussed. Actual operation results and the comparision of the complexity between present algorithm and the traditional matrix algorithm verify the high effectiveness and good fault-tolerant ability of this algorithm.
