| Abstract: | Wavelet analysis is a brand-new time-frequency analysis technique.A simple and useful method on fault detection and signal denoising for water turbine generator sets is studied in this paper.This method is based on the differences of wavelet transform maxima on fault signal,background signal and noise. |
| Keywords: | fault diagnosis signal detection wavelet analysis noise water turbine generator set |
