Condition Monitoring And Diagnosis System Of Hydroelectric Generating Set

With the fact that the water turbine generates electricity, the industry fleetness develops, the malfunction diagnose technology has got broad taking seriously as a result because the operation request to large-scale revolution equipment is more and more high. The accident examining and repairing method, being that the plan examines and repairs a sum mainly overhauls the water turbine generating set in the past, though being able to ensure that safety works to a certain extent, but bring about problem such as keeping deficiency in repair excessively or keeping in repair usually, it waste large amount of manpower and material resources. Examine and repair obvious system defect relative to tradition, Owing to that the state that equipment state appraises monitors a sum, trouble shooting is outstanding comparatively. That pattern consumes a minimum, and safety, stability, high grade run for equipment the guarantee having provided the reliable technology and managing. It is just because that state examines and repairs existence gigantic economic effect, having considerable application value, examining and repairing way therefore carrying out this pattern's is very necessary.The state the main body of a book having been formed specifically for the hydraulic generator, analyses equipment monitors a technology, introduced that equipment state in diagnosing monitors method. Specifically for equipment runs the large amount of nonlinearity there existing in middle, phenomenon, the main body of a book has designed a wavelet analysis module. There exist certain limitation in middle because of FFT in the treatment shaking a signal, But wavelet alternation has time-frequent characteristic property, can guarantee information completeness. Therefore, while introducing mathematic model and physics significance that the wavelet shifts, have set forth its application. Such can coordinate the diagnose module right away, penetrating reporting being in progress to equipment operation state, and the method having introduced the signal treatment being related to that. Govern measure by analysis, knowledge and malfunction having formed the corresponding expert to common malfunction of hydroelectric generating set mechanism. Monitoring hit the target practical experience combining with state, make use of Delphi7.0 to have realized the operation state simulating reality of water wheels aircraft crew.
