Study on Fault Diagnosis Model of Condensate and Feed Water System Based Information Fusion

Based on the analysis of condensate and feed water system, a fault knowledge repository is established considering operation experience. The D-S inference of Information Fusion theory has the ability of dealing with uncertain information and Artificial Neural Network (ANN) has the advantage of high tolerance and robust. In this paper, a model for fault diagnosis utilizing D-S theory of evidence together with BP network is presented and introduced to the diagnosis of condensate and feed water system. The simulation experiment proves that the system is able to improve the reliability of the diagnosis and decrease the uncertainty markedly.
