Methods of Quantitative Model Validation for Linear and Non-Linear Systems, with Applications to Nuclear Power Plant

摘要

The report presents a number of techniques developed at Winfrith for assessing and improving dynamic simulation models. A method for selecting best-fit parameters for control engineering applications is discussed, and the concept of model-distortion is developed, whereby a model's worth may be assessed quantitatively by the extent of time-variation or distortion needed in its nominal constant parameters to match a recorded transient perfectly. Four examples taken from nuclear power station experience are described where model-distortion techniques have been applied. (Atomindex citation 14:807100)
