Examples
- Judging by the different magnitude and direction of the wavelet packet coefficient modular maximum , we can select the single phase - to - earth line
利用各个出线零序电流在能量最大频带上小波包系数模值的大小和方向的不同来实现故障选线。 - The background interplanetary magnetic field is spiral with a vanishing south - north component , the initial ionosphere is dominated by the region field - aligned current ( fac ) and the corresponding dawn - dusk electric field , and the interplanetary shock collides with the earth along the sun - earth line
背景行星际磁场为螺旋场，南北分量为零；初始电离层由区场向电流和相应的晨昏电场所主导；行星际激波沿日地连线方向撞击地球。 - Judging by the different magnitude and direction of the wavelet packet coefficient modular maximum , we can select the single phase - to - earth line . the method using wavelet singularity detection theory to extract the fault time is discussed . a fault distance measurement algorithm combining wavelet analysis used for separating the character from the transient fault signal with artificial neural networks used for the nonlinear approximation from the transient character to fault distance is presented
论文提出利用各个出线零序电流在频带上小波包系数模极大值的方向和大小的不同来实现故障选线，讨论了利用小波分析的奇异性来判断故障启动时刻，提出将小波分析和人工神经网络结合，利用人工神经网络的非线性逼近能力，实现故障暂态量到故障距离的非线性映射，完成测距。
