The invention relates to an event-driven and directed graph search-based remote operation fault diagnosis method, which is applied to an intelligent substation. The method encodes the remote operation process events of the intelligent substation according to the remote operation process of the intelligent substation, and collects remote operation fault knowledge entry, constructing a smart substation control remote operation fault diagnosis knowledge base; converting the smart substation control remote operation interaction logic and fault diagnosis knowledge base into a directed graph representation; through the smart substation control remote operation event message and related secondary equipment operation Monitoring and collection of status messages to obtain status messages of smart substation control remote operation events and related secondary equipment operation status; based on the discovery of smart substation control remote operation fault events, drive fault diagnosis directed graph path search to obtain smart substation control remote operation faults The causality chain of the smart substation control remote operation fault diagnosis results are finally given.
Description
technical field [0001] The invention belongs to the field of electric power system automation, is applied to intelligent substations, and particularly relates to a method for diagnosing faults in remote control operations based on event-driven and directed graph search. Background technique [0002] The remote operation of smart substation regulation includes the 104 protocol interaction link between the master station of the dispatch automation system (control master station) and the remote machine of the smart substation, the MMS protocol interaction link between the remote machine of the smart substation and the measurement and control device, and the communication between the measurement and control device and the intelligent terminal. In the GOOSE protocol interaction link between smart substations, remote operation fault analysis and troubleshooting of smart substation control, it is necessary to collect and analyze the messages of each protocol interaction link: [00...
