As. Erbay et Br. Upadhyaya, A PERSONAL COMPUTER-BASED ONLINE SIGNAL VALIDATION SYSTEM FOR NUCLEAR-POWER-PLANTS, Nuclear technology, 119(1), 1997, pp. 63-75
The safe operation and efficient control of a nuclear power plant requ
ires reliable information about the state of the process. Therefore, t
he validity of sensors that measure the process variables is of great
importance. Properly validated process signals are also beneficial fro
m the standpoint of increased plant availability and reliability of op
erator actions. Signal validation is implemented by using various algo
rithms. The effectiveness of a few other techniques during steady-stat
e and transient-operating conditions are investigated. These algorithm
s are implemented in a personal computer-based system, along with a fu
zzy logic decision-making module. The effectiveness of the overall sys
tem is demonstrated using data from operating power plants.
