Abstract: To solve the problems of vague description, undefined interval and missing alarming level existing in centralized power grid monitoring information, this paper proposes a method for generating and checking D5000 alarm information based on semantic analysis. Firstly, the automatic generation of D5000 alarm information table is realized by referring to expert knowledge base theory. Besides, the basic logic variables are automatically extracted from the alarming information table by character decomposition. Based on a comparative analysis of D5000 and ON2000 information tables, the checking and error-correcting function is also accomplished. A case study of a 110 kV substation shows that the method is valuable in simplifying the manual checking process, improving the information processing efficiency, and optimizing the management level of monitoring information.
