Abstract

A technique utilizing parity-space representation (an efficient method for finding a consistent subset of redundant measurements) and analytic redundancy (relationships among dissimilar variables) is designed for use in a real-time digital-computer-based system to isolate sensor and non-sensor component failures in the steam generator and feedwater subsystem of a reference nuclear power plant. The technique has correctly isolated a variety of sensor failures inserted during both steady-state and transient computer simulations of the reference plant. In particular, the technique's ability to detect both sensor and non-sensor failures would be extremely useful for a disturbance analysis and surveillance system.
