Title
(EN) APPARATUS AND METHOD FOR ANALYZING POWER PLANT WATER CHEMISTRY
(FR) APPAREIL ET PROCEDE POUR L'ANALYSE DE LA COMPOSITION CHIMIQUE DE L'EAU D'UNE CENTRALE
Abstract
(EN)
A power plant water chemistry analysis apparatus and method relies upon water chemistry sensors to obtain power plant water chemistry data (34) characterizing the chemical activity of a power plant water system. An analytical model processor (36) is used to generate model predictions for the power plant water system. A statistical data fitting processor (38) selects screened data from the power plant water chemistry data that corresponds to the model predictions. The screened data is processed by an artificial intelligence processor (40) to derive power plant water chemistry diagnostic information (42). The artificial intelligence processor (40) includes an expert system (50), rule base (52), plant water chemistry system simulator (54), and pattern recognition module (56).
(FR)
Dans un appareil et un procédé d'analyse de la composition chimique de l'eau d'une centrale, on utilise des capteurs permettant de produire des données (34) relatives à la composition chimique de l'eau de centrale, caractérisant l'activité chimique du circuit d'eau d'une centrale. Un processeur de modèles analytiques (36) est utilisé pour la génération de prédictions de modèles pour ledit circuit d'eau de la centrale. Un processeur (38) d'adaptation des données statistiques sélectionne les données sélectionnées parmi les données de composition chimique de l'eau de centrale, qui correspondent aux prédictions de modèles. Les données sélectionnées sont traitées par un processeur (40) à intelligence artificielle de sorte que les informations diagnostiques (42) relatives à la composition chimique d'eau de centrale soient dérivées. Le processeur (40) à intelligence artificielle comporte un système expert (50), une base de règles (52), un simulateur (54) de systèmes de compositions chimiques d'eau de centrale et un module d'analyse typologique (56).
