Abstract

Poor control of the steam generator water level in the secondary circuit of a nuclear power plant can lead to frequent reactor shutdowns. Such shutdowns are caused by violation of safety limits on the water level and are common at low operating power where the plant exhibits strong nonminimum phase characteristics and flow measurements are unreliable. There is, therefore, a need to systematically investigate the problem of controlling the water level in the steam generator in order to prevent costly reactor shutdowns. This paper presents a general framework for addressing all aspects of this problem using model predictive control techniques.

Bibliographical note

Funding Information:
As part of our future work, we plan to use a time-varying version of the Kalman filter gain in the MPC estimator to account for the varying plant model and also the variation in the intensities of the process noise over the operating power range. We also plan to incorporate a priori knowledge of future power/set-point changes in the algorithm. Such a modification is expected to address the problems related to the inverse response behavior of the plant. The study of the closed-loop stability of this LPV MPC design remains an issue to be explored.
