| Abstract: | A vibration monitoring and fault diagnosis system for gas turbine power generator is introduced in this paper.It includes data processing,vibration monitoring,predicting and diagnosing of the fault of generator.The vibration signal is processed by spectrum analysis,wavelet and STFT.For long time running of the generator,the system can give state trend analysis and fault alarm.The system built a database of fault diagnosis and carried out the fault diagnosis of gas turbine's key.The operating state the Titan gas turbine had been tested and analyzed using the system.Results show that the system's software and hardware can satisfy the requirement of vibration monitoring and the fault diagnosis of such kind of gas turbines. |
