Construction of regional grid intelligent alarm system

The main alarm information of the grid includes the normal operation message, the accidents information and the warning message. In order to process the alarm information separately and offer the initiative treatment options for dispatchers, an intelligent alarm system for regional intelligent grid is constructed in the paper. Alarm signal classification and expert reasoning were carried out based on the signals´ importance in the system. With fuzzy matching method the alarm signals were associated with the alarm knowledge base automatically. By single event reasoning and multi-event reasoning methods, alarm information is reasoned as well as judged according to the logic of knowledge base in the intelligent alarm system.
