This thesis studies the law of affecting de - noise result and the selection of the threshold and the wavelet function , the combination of wavelet and fft in the fault diagnosis of turbine - generator sets : by the de - noise anslysis of blocks and sin signals , concludes : to blocks signals , usually adopts soft threshold ; the law of affecting de - noise result is when use wavelet auto - de - noise , with the increasing of decomposed level , the de - noise result becomes worse while the level blow the 3 , when the level above 3 and when uses wavelet packet , it is the other way round ; the best de - noise methods of the signal is that uses " dbl " wavelet function , three level , soft and " rigrsure " threshold
本文研究了分解层数对消噪结果影响的规律和阈值、小波函数的选取，结合小波分析与fft分析诊断汽轮发电机组的故障。通过对brocks和sin两信号的分析，得出：对blocks信号进行分析一般采用软阈值；分解层数对消噪结果影响的规律为用小波自动降噪在分解层数小于3时，随着分解层数的增加，消噪结果变好，反之，则变差，用小波包降噪时随着分解层数的增加，消噪效果变好；适宜选用dbl小波软rigrsure阈值自动消噪。
