Design and operation of the communication alarm processor expert system
This paper discusses the expert system design, verification testing, installation, and initial operating experiences of the Communications Alarm Processor (CAP), a prototype expert system developed for Bonneville Power Administration (BPA) by Oak Ridge National Laboratory. The system is designed to assist operators by receiving and diagnosing alarms from Bonneville's Microwave Communications System. The microwave system transmits data from power facilities in four Pacific Northwestern states to Dittmer, Bonneville's central operations control center. The prototype is limited to one of seven branches of the communications network and a subset of alarm systems and alarm types. CAP receives real-time data, diagnoses operational problems, archives alarm information, and supports analysis aimed at improving equipment maintenance. The expert system operates in an advisory capacity so diagnoses are presented to operators for their review and concurrence before being archived. CAP employs a backward chaining approach for diagnosing alarms. The system, which was delivered in January 1989, resides on a VAX 3200 workstation under the VMS operating system and utilizes C code to retrieve and process alarm data. An expert system shell, Nexpert Object, was used to develop the expert system. The ultimate goal is to develop expert systems that will enhance power system operation and maintenance. 7 refs., 8 figs., 1 tab.
