A Generalized System State Analyzer for Plant Surveillance

Abstract

Very large, dynamic, complex systems such as electrical power plants, both fossil and nuclear, are designed using a host of physical parameters that interact with each other on a first-principle basis and via control actions and reactions. Examples of these parameters are pressures, temperatures, flows, voltages, etc. When the plant is built, it is instrumented with thousands of sensors and actuators to both determine and control the design parameters. When the plant is operated, a major problem is ensuring all the parameters are where they ought to be.
