| 摘 要： | 现场局部放电在线检测过程中常伴随有白噪声和窄带周期性干扰,为局部放电信号的检测带来很大的困难.为了从强的噪声干扰中有效的提取局部放电信号,本文提出了一种小波包变换和广义形态滤波器相融合的新方法对含有强噪声的局部放电信号进行去噪.结果表明该方法能够有效的消除局部放电信号的噪声,同时能很好的保留原信号的特征,解决了滤除混合...

| Abstract: | The white-noise and periodic narrow-band interference is often accompanied with on-site detection of partial discharge(PD),which makes the detection of the signal bring great difficulties.We put forward a new method that interfuses wavelet package transform with generalized morphological filters for denoising in order to extract the PD signal from intensive noise.The results show that the presented method can eliminate the noise existing in PD signals effectively and the characteristics of original signals ... |
