A distributed microcomputer system is being developed so that eight gas turbine generators can communicate over simple serial “party” cables to computers located in a central control room. There, the Station Operator’s Console gives an operator full control over the turbines, while presenting status and annunciator information on two CRTs. Redundant microcomputers inside this console drive two “party” cables for improved reliability. These microcomputers interface through telemetry equipment to the system dispatch center 60 Km from the turbine site, completing a command sequence for eight turbines in 2.5 sec. When the system is not processing commands, it collects data for the maintenance minicomputer. Over 200 signals from each turbine generator are used to create a significant data base on dual disk drives. The maintenance computer generates several logs, condition analyses and plots to support diagnostic and maintenance messages.
