| Abstract: | Stack gas turbine is core equipment in production, so scientific maintenance of the turbine appears to be important to ensure its safe and reliable operation. The muhi-sensor information fusion algorithm is briefly introduced ;a neural network with the D-S evidence of a combination of diagnostic methods is provided ; and a multi-sensor fusion-based algorithm fault diagnosis of the gas turbine model is proposed, Experiment result shows that the method enhances the system flexibility,the efficiency and accuracy of the fault diagnosis. |
