Description

The problem of detecting a small water loss at the feedwater-system is treated. The developed model of the feedwater-system is allow us to use dedicated Kalman filter/DKF/ ? in order to estimate the fluid flow in the pipes. An eventual leakage in one of the side-pipes causes a constant shift in the mean of the proper component of the innovation calculated by the DKF. This shift is detected by a modified version of Wald's SPRT. (author)
