In large power generating stations, signals from various instrumentation systems are channeled to control systems, protection systems, and plant monitoring systems. Validation of these signals accomplishes the following goals: minimize plant downtime, increase the reliability of operator decisions, and as an aid for scheduling plant maintenance. The signal validation methods developed under this project are designed to perform various levels of signal processing, and to detect, isolate and characterize faulty signals. A central database stores information about sensors, history of signal validation results, plant data, and subsystem models. The signal validation architecture consists of parallel signal processing modules, each of which implements a diverse validation scheme. The software development and testing of all the modules is performed using IBM PC/AT computers. All the signal validation modules are ready for preliminary implementation and are tested using operational data from a pressurized water reactor (PWR) and PWR data from the Combustion Engineering Nuclear Transient Simulation code.
