A Summarize on De-noising Technology of High-frequency Noise for Hydropower Generating Unit

LI Zhi-hong(Nanchang Institute of Technology,Nanchang 330099,China)  
The main methods for vibrating signal de-noising of hydropower generating unit are reviewed.The currently used de-nosing methods are classified into two categories: the traditional vibrating signal de-noising based on Fourier transform and the new model vibrating signal pre-processing technology represented by the pre-processing method,the advantages and disadvantages of the two categories are analyzed respectively.Second generation wavelet transform for vibration signal pre-processing have advantages that fast for computation,no need choice for wavelet basis function,results are reasonable.The developing direction of signal de-noising technology is further discussed at the end of this paper.
