Abstract
A control room complex for a plant having three independent computer systems (i.e., DIAS for indication and alarm, DPS for general monitoring, and PPS for protection), whereby a representative value of a parameter common to all systems can be validated in each of the DIAS and DPS based in part on values in the PPS, and an overall representative value displayed to the operator via the DPS. The content of and hierarchical access to three levels of display pages containing information on critical function monitoring and success path monitoring are disclosed, as well as the use of alarm indication on the overview (IPSO) display to initiate diagnosis of challenges to critical functions or unavailability of success paths, and further alarm-based guidance toward ultimate diagnosis. <IMAGE>
Description
2272326 PLANT MONITOR SYSTEM This invention relates to a plant monitor
system which could for example be used in connection with the control of operation of a commercial nuclear power plant.
Conventionally, commercial nuclear power plants have a central control room containing equipment by ^iiich the operator collects, detects, reads, compares, copies, Complite.s. compiles, analyzes. confirms, monitors, and'or verifies many. bits of information from multiple indicators and alarms. Conventionally, the major operational systems in the control room have been installed and operate somewhat independently. These include the monitoring function, by which the components and the various processes in the plant are monitored: contro l, by. which the components and the processes are intentionally altered or adjusted, and protection, by which a threat to the safety of the plant is identified and corrective measures immediately taken.
The result of such conventional control room arrangement and functionality can sometimes by information overload or --,timulus overload on the operator. That is, the amount of information and the variety and complexity of the equipment available to the olx.rator for takiner action based on such extensive information. can e-,ceed the operator's cognitive limits, resulting in errors.
The most famous example of the inability of operators to assimilate and act correctly based on the tremendous volume of information stimuli in the control room, particularly during unexpected or unusual plant transients, is the accident that occurred in 197S at the Three Mile Island nuclear power plant. Since that event, the industry has focussed considerable attention to incrcasin=-, plant operability through improving control room operator performance. A key aspect of that:L-npro-,-ement process is the use of human engineering desigan principles.
Advances in computer technology since 1975 have enabled nuclear engineers and control room designers to display more inf ormation, in a greater variety of ways, but this can be counterproductive, because part of the problem is the overload of information. Improvin- "user friendliness" while maintainina- the quantity and type of information at the operator's disposal has posed a fornLidable engineering challenge.
