Description: 局部放电试验所采集的信号中往往混有白噪声、周期干扰信号去除。此处采用常用db系列小波中的db6小波进行9尺度的多分辨分解后，根据白噪声能量特性，估算各尺度的阈值大小，采用硬值进行处理，后进行重构。-Partial discharge test of the signal collected is often mixed with white noise, periodic interference signal removal. Here the use of commonly used wavelet db Series DB6 wavelet carried out in the 9-scale multiresolution decomposition, based on the energy characteristics of white noise to estimate the scale threshold size, the use of hard-value deal, after the remodeling.

Description: This paper is a brief introduction to discrete wavelet transform as digital signal-processing
technique and the application. The field of discrete wavelet transform (DWT) is an
amazingly recent one because itÌ s better than Fourier transform. This technique was used on
power system to partial discharge site location. Partial discharges are caused by various
defects such as voids, shield protrusions, contaminants, advanced stages of water tree, etc
and known the main cause of breakdown in insulation materials. Platform: |
