Abstract
In this article, the wavelet analysis method is used to detect and analyze voltage sag signal contaminated by white noise. A new threshold selection method based on the wavelet decomposition layer is proposed, in view of the characteristic of noise coefficients which decrease when the scale increases. This method can obtain the superior wavelet coefficients estimation through adjusting two adjustable parameters. This method has the better ability for reducing noise interference.
