Seminar on Expert Systems Applications in Power Plants

BACKGROUNDEngineering, operation, and maintenance offossil and nuclear power plants require applica-tion of expertise in many engineering disci-plines. Typically, the expertise required to findthe solution to a given technical problem isacquired through many years of experience inpower plant equipment design, operation, moni-toring, analysis, and control. Such experience isavailable among a small number of "experts" inthe power industry. Maintaining this expertise offield engineers and power plant operators is amajor challenge to the power industry.Expert Systems or Artificial Intelligence (Al)technology enables the knowledge of theexperts to be captured in symbolic computerlanguage. When the expert consultation is notreadily available, these computer programs canhelp the plant staff diagnose equipmentmalfunctions. The expert system software canduplicate the line of reasoning used by humanexperts and the users can interactively followand question the reasoning process before tak-ing desired corrective actions.Although relatively new to power plants, Al tech-niques have been used in applications outsidethe electric power industry for many years. Thetechnology for building expert systems alreadyexists in the form of expert system "shell" com-puter programs. These programs permit appli-cation-specific knowledge to be programmed inan English-like symbolic language in the form of"rules" that are easily understood by non-com-puter specialists. Expert System shells havebeen developed for a wide range of computers,from computers built specifically for Al applica-tions to desk-top personal computers. Specificapplications are now available or under devel-opment to address a number of problems ofinterest to power plant personnel.

OBJECTIVESThe objectives of this seminar are to:" Provide a forum for utilities to discuss the

potential of expert systems and Al technologyin power plant applications

" Assess the state of the art of expert systemsfor power plants

" Review utility experience with expert systems

" Conduct working groups that discuss specifictopics related to expert systems and defineneeds for EPRI-sponsored activities in thisarea

WHO SHOULD ATTENDTechnical managers and utility engineersresponsible for plant performance and opera-tions, equipment maintenance, diagnosis andcontrols; engineering consultants; expert sys-tems developers; and vendors will find this sem-inar beneficial.

EXHIBITThe conference will be supplemented with anexhibit that demonstrates a representativeselection of EPRI and commercially developedproducts using expert system technology. Manyof the products on display at this exhibit willalso be the subject of papers presented in thetechnical sessions.

ONSITE MATERIALS AND PROCEEDINGSEach attendee will receive a three-ring binderwith a copy of the papers presented at theconference.In addition to this agenda, a few papers (fromthe United Kingdom, France, Czechoslovakia,Switzerland, etc.) have yet to be confirmed forpresentation. A final agenda will be distributedat the meeting.
