This paper presents the details of a prototype of an intelligent alarm processor called the Advanced Alarm Processor (AAP). The AAP uses model-based reasoning methods to synthesize and suppress power system alarms in the on-line environment. These model-based reasoning and processing methods are a new approach to intelligent alarm processing. The transformer model presented in this paper is a subset of the complete AAP which also processes power system, communications, protection, and substation alarms. The transformer module is used to demonstrate the reasoning and message-handling methods. Finally, the utility of the AAP is demonstrated through tests in which raw energy management system (EMS) input alarms are processed by the prototype to produce higher-level messages
