Graphical power network topology analysis based on adjacency matrix

This paper introduces the network topology model based on object oriented,and on this basis defines elements classes according to different types of elements.Analyzing the adjacency matrix which generated automatically can get the topology relations which can be modified dynamically based on the changes of switches among the nodes commendably and accomplish the task of topology analysis,i.e.the division of equivalent nodes and electrical islands.This method avoids n-1 times matrix multiplication with itself which is involved in the traditional adjacency matrix algorithm,and also improves the efficiency.Real application shows that this algorithm based on adjacency matrix is of certain practical value.
