Network topology for the application research of electrical control system fault propagation

Fault diagnosis and failure analysis is crucial issue in the process of health management and predicative maintenance for large complex system. Fault propagation and its cause-effect relationship in the system are of priority with regard to the fault diagnosis. The fundamentals for modeling the network topology are presented according to the characteristics of the electrical control system connection relationship and its functionality, a complex network topology model was built subsequently. The cause and effect relationships of the components are mapped to the relationships of the vertices in a complex network. The search method for the fault propagation path from the source vertex to the target vertex is studied using node coordinates connections, and application research of electrical control system fault propagation is shown and discussed in the paper. The proposed method is practical in dealing with the fault analysis and evaluation for large complex systems.
