Abstract :There are a lot of transducers installed on turbo2generator units. How to use the data sufficiently and to improve the ac2 curacy of fault diagnosis are important problems. Turbo2generator fault diagnosis method based on the information fusion theory is presented in the paper. Information fusion examples based on the Bayes decision method and dynamic model are presented. Con2clusions are given in the end of the paper.
Key words :information fusion;fault diagnosis; sensor
