Reliability models of overhead power lines in the calculation algorithm based on network topological analysis

Abstract

The article proposes an approach to the analysis of the reliability of high-voltage transmission lines developed using topological concepts of analyzing the structure of networks in the electric power industry. The study used practical power distribution schemes used at hydroelectric power plants in the East Siberian region. On the basis of the probabilistic model, a computational algorithm has been formed, software for assessing reliability has been developed. Using the described tools, a numerical assessment of the reliability indicators of outgoing high-voltage power lines 220 kV was carried out.
