• This thesis chooses b spline wavelet that adapts to the analysis of power system signal , and uses the wavelet transformer to analyze the magnetizing inrush current and inner fault current . a transformer microcomputer protection was designed in this thesis , and in the base of intermission angle principle , a new criterion was established , which pierces through the traditional method with accurate measurement of intermission angle , but analyses the wave by wavelet transform . this criterion is lower in hardware , so it will be realized in the existing hardware
  本文选择适合电力系统信号分析的b样条函数作为母小波，对励磁涌流和内部故障电流进行小波分析，并设计微机型变压器保护基本配置，在以往间断角原理鉴别励磁涌流的基础上，突破传统精确测量励磁涌流间断角的方法，直接对信号小波变换后的波形进行分析，建立一个新的鉴别励磁涌流判据，该判据对硬件要求不高，可以在现有一般硬件平台上实现；并编写以b样条函数为母小波的小波变换判据算法程序。
• Secondly , the wavelet transform of ae signals collected in experiment is carried out with db6 wavelet and scale 3 on the basis of the signal ' s frequency analysis . the high frequency d , signal is ae characteristic signal . and by choosing the level ' s wavelet coefficient as its input , the wavelet - neural networks can be trained with the data of ae experiment , and the ae signals can be effectively recognized
  然后，在实验与对实验所采集数据频谱分析基础上，根据对小波分析用于信号处理可行性研究，本文选择db6母小波、尺度j = 3对实验所采集数据信号进行小波变换，变换后其高频成分d _ 1信号即为声发射特征信号。
• Where several mother wavelet functions were used to expand a function , it also can be seen as vector - valued wavelets that satisfy conditions in which matrics are involved . the main works of this paper are as follows : firstly , although haar function has bad vanish property in frequency domain , it is the only normal orthonormal basis with symmetry and real short - support property
