| Abstract: | In order to diagnosis the operation status of wind turbines, an analytical method was proposed, which was based on routine analysis, vibration amplitude analysis and waveformspectrum analysis. According to the characteris tics of wind turbines, the amplitude analytic technique and waveformspectrum analytic technique were expounded in detail. At last, an example of seeking abnormal noises source of a wind turbine was presented. The results showed that the analytical method was completely feasible and it provided a method for wind turbines fault diagnosis technique. |
