摘要
小波分析在高压电器放电检测中有很大的优越性 ,最优小波基的选择是小波分析的应用中的重要问题。选择小波函数的有效方法是 :先找出满足允许条件的小波 ,按小波函数与信号的相似性粗选后以总熵值最小标准确定最优小波函数。以此方法选择了适合于放电声发射信号小波分析的小波函数 。
Wavelet analysis is very preponderant in acoustic emission detection of discharge in high voltage equipment. In its application, selection of best basis is important. In this paper, an effective method to select best basis is proposed and based on the method a best wavelet function for acoustic emission detection of discharge is selected. An example shows the selected wavelet function is feasible and effective in acoustic emission detection of discharge.
