| Abstract: | The paper presented a fault feature extraction method for rotating rectifie of three-stage generator.It classified the common faults of rectifying tube.The fault model was established and fault signal was obtained through the simulation.The energy eigenvector was obtained from wavelet packet analysis of the fault signal,and then the wavelet reconstructioned the signal,which lay a solid foundation for fault diagnosis of rotating rectifie. |
| Keywords: | three-stage generator rotating rectifie wavelet packt analysis feature extraction |
