Research on fault localization methods of shipboard power networks

Aiming at the complexity and networked characteristics of shipboard electric power network, complex network theory thinking is introduced to transform the electric power network into a network topology graph, using the reliability theory, combined with the minimum path method, the nodes with a large contribution to the failure rate are set as the network fault monitoring points for real-time monitoring of the network. In order to solve the problem of fault location in shipboard electric power network, this paper utilizes the shortest circuit idea to realize the search and location of faulty segments, and simulation experiments are carried out for the two cases of line failure and node failure, and a relatively good location effect is obtained.
