Abstract

A method for initializing and updating a network model includes forming a network topology in the form of a network graph and basing it on the object of specifying a method which can be realized by a computer program that can be processed with a short computing time. Such methods are used, for example, in network master computers of an electrical power supply network, with the network topology established being the basis for indications or calculations. In the method according to the invention, the network topology is formed by applying and expanding sparse vector methods and sparse matrix methods by the following steps: providing captured networked topology data in the form of a terminal adjacence matrix, transforming the matrix into an upper triangular matrix, initializing the upper triangular matrix, forming the matrix products for rows of the upper triangular matrix, forming a path table from the upper triangular matrix, updating the upper triangular matrix in the case of a change to the captured network topology data, updating the path table and identifying components of the network graph using the path table.
