Research of Improved Credibility Theory for the Fault Diagnosis of Condenser

Abstract:

Research on fault diagnosis of condenser has a great significance to safe and efficient operation of power plant. In view of shortcomings of existing diagnosis methods, this paper proposed a fault diagnosis method of condenser based on improved credibility theory，and applied the merits of credibility reasoning to the fault diagnosis of condenser. By proposing a more rational expression way of symptoms and some mathematical equations which can convert field data into symptoms’ credibility, this paper provided a solid basis for acquiring symptoms’ information accurately. Meanwhile, the setting method of rule confidence of credibility rule was improved, which can make the process of credibility reasoning closer to human experts thinking. Experiment results show that this model meets the demand of condenser fault diagnosis well and has important theoretical significance and practical value.
