A Kalman filter for poisoned reagent feed streams

Technical Report ·
OSTI ID:6973626
A Kalman filter was designed for a reagent feed system to reduce the noise in an analyzer measurement used to initiate shutdowns of the system under accident conditions. The filter's performance was validated by simulating plant conditions and also in a plant test. The standard deviation in steady state analyzer measurements, processed as a 36-second moving average of one second readings, was reduced by 33% using the Kalman filter estimate. Additionally, unmeasured leaks to the system were estimated by the filter providing a means of incipient failure detection against dilution of the reagent vessel's contents. 10 refs., 13 figs.
