This paper describes the functions, the advantages, and the performing steps of preventive control in power plants, and presents the methods to construct this prototype expert system. The differences between preventive control and diagnosis are also described. Preventive control consists of two major areas: (1) Correction of process control of generator system, and (2) prevention of equipment failure. This system uses frames along with rules to construct a large knowledge base. there are three main methods for developing the knowledge base; (1) Constructing root frame and subframes according to the properties of operational process and equipment; (2) determining all parameters used in the knowledge base; and (3) turning the expertise into rules by means of decision trees. Examples are presented for describing this prototype expert system.
