If there was a fault in the transmission network with no safety measure, it might produce unpredictable losses and consequences, so fault diagnosis of the power grid had become an important research object. The alarm information generated by the fault was complicated, which increased the difficulty of staff fault diagnosis. Based on the above problems, a fault diagnosis method for transmission network based on rule reasoning was proposed by this paper. By establishing the Petri network model of the power network, the structural information of the diagnosable subnet of the fault transition was analyzed and the flow of tokens in the diagnosable subnet was described,then the fault element location was determined through the related fault rule reasoning, and the fault simulation calculation was carried out by using the local circuit diagram of IEEE-14. The results showed that the rule based on reasoning fault diagnosis method could accurately and quickly locate and analyze the fault of transmission network, and it was a reliable and effective fault diagnosis system.

Key words: transmission network, Petri network, fault diagnosis, fault identification, rule reasoning, network information flow, directed network
