Reliability Evaluation of Distribution System Considering Partitioning and Fusion of Hierarchical Structure
摘要
Abstract
A reliability evaluation algorithm for distribution system, in which the partitionings and the fusion of hierarchical structure are taken into account, is proposed. Firstly, according to the differences among functions the partitionings are divided into two sorts, namely the manual ones and the automatic ones, and a reachable matrix based partitioning method is put forward. On this basis, the hierarchical structure of manual partitionings and the hierarchical structure of automatic partitionings are constructed to solve the fault duration and fault rate of load nodes respectively. The hierarchical structure begins for the power supply point and extends downward to the boundary nodes of the distribution system. To avoid repetitive computation, the reliability data of each hierarchy is recorded while this hierarchy is being computed, and this hierarchy is taken as the new root node for subsequent extension. The proposed algorithm integrates the advantages of partitioning, the minimal path method and hierarchical structure, so it possesses strong operability and is high efficient. Besides, using the proposed algorithm, the reliability index of the specified node can be obtained directly, so it is suitable for the analysis on the reliability of distribution system containing important power consumers.关键词
