PROBLEM TO BE SOLVED: To provide a failure diagnosis system capable of diagnosing and specifying the failure site of a power generating system requiring no professional knowledge to be able to suppress a wrong diagnosis at the time of failure.SOLUTION: A failure diagnosis system includes a database DB in which past failure data Dp including state identification information h and detection signal history L at the time of failure in the past are matched with failure diagnosis results O and failure countermeasure recording C and recorded. When failure occurs in a power generation system GS, failure data D including the failure state identification information h and the detection signal history L is generated, the past failure data Dp in which the failure data D matches with the failure state identification information h is extracted from the database DB, a correlation relationship between the extracted past failure data Dp and the failure data D is obtained, the past failure data Dp having a strong correlation relationship is selected from among the past failure data Dp from which the correlation relationship is obtained, and the failure diagnosis results O and the failure countermeasure recording C recorded while being matched with the selected past failure data Dp are output.SELECTED DRAWING: Figure 1 |
