基于节点支路链矩阵的配电网动态拓扑分析方法研究与应用
Application of distribution system dynamic topology analysis based on node branch chain matrix
摘要
Abstract
In view of the disadvantages of computing complexity,slow calculation rate and poor reusability in topological analysis methods,and while the scale of distribution system is extended or the state of switchers changed,it is not easy to reflect the network topological dynamic rapidly.This paper proposed a new high-speed dynamic topological analysis method of distribution system.Under the normal operation,the distribution system would be divided into multiple branch chain according to the characters of the nodes and established the node branch chain matrix to describe network structure.The static electrical islands of distribution system were quickly completed analysis by using the adjacency matrix notation.If the network structure was dynamic changed,it locally modified the topological structure and the node branch chain matrix of distribution system by using direction depth-first search method.Numeric experimental results show that the proposed method reduces significantly the node number in the process of search.It has low computational complexity and improves the dynamic topological analysis speed of distribution system.It provides an effective method for dynamic analysis of different distribution network structures.关键词
