Research on Fault Analysis Method of Power Communication Digital Twin Network Based on Rules and Cases

In order to determine the root cause of the fault from the alarm of the power communication network, the fault analysis rule base based on the combination of fault alarm event tree and code book method rules is adopted by using digital twin, and the fault handling case base accumulated gradually is combined to realize the intelligent analysis and handling of the fault. The fault analysis technology combining rules and cases improves the fault handling of the power communication network.
