Based on the classification, processing and reasoning of the alarm information of the smart substation equipment when the fault occurs, the intelligent alarm of the fault is realized. In this paper, the working process of the intelligent alarm was sorted out, and according to the severity level of intelligent substation alarm information, the staged processing of the information was carried out, and the alarm information was displayed. Then through analyzing the SCD configuration file of the intelligent substation, the secondarynetwork topology was drawn and then it was interconnected with the alarm information, thus narrowingthe positioning scope of the fault point. Later, the reasoning knowledge base was established based on the intelligent alarm expert system, so that the fault could be quickly located and eliminated when the alarm occurred. The effectiveness of the method was verified by practical reasoning cases.
