| 摘 要： | 针对小波分析中所用到的小波函数具有不唯一性及用不同的小波基函数分析同一个问题会产生不同结果的特点,对于普遍应用的Daub4小波和Meyer小波,在各种不同类型的电能质量分析中的结果进行了比较.结果表明,在几乎所有的暂态问题中,Meyer小波的检测能力都要优于Daub4小波.

| Abstract: | In wavelet analysis,even for a same problem,using different wavelet function may cause different results.The performances of the commonly used Daub4 wavelet function and Meyer wavelet function were compared in several different styles of power quality analyses.The results show that the detecting ability of Meyer wavelet is more excellent than Daub4 wavelet in the analyses of almost all kinds of transient problems. |
