Fault diagnosis of a steam generator based on gray cognate analysis

The principle, procedure and method of fault diagnosis were introduced by using gray cognate analysis firstly.According to the fault analysis of marine nuclear power plant steam generator, the fault diagnosis method of the steam generator was presented based on cognate analysis. The research results show that it is feasible to introduce gray cognate analysis into fault diagnosis of a steam generator. The method described in this paper has the advantages of simple technique, fewer calculation and reliable diagnosis.
