摘要
提出了非二进小波变换方法。非二进小波变换方法简便 ,不需要迭代 ,可以提出信号的任何整数次和分数次谐波分量 ,具有比二进小波变换更强的信号处理能力和灵活性 ,因而适用于电力系统故障信号分析。此外 ,文中利用非二进小波变换的原理 ,提出了基于非二进小波变换的电力系统微机保护数字滤波器与算法 ,这对于提高电力系统微机保护的可靠性具有重要意义。
In this paper, method of non-dyadic wavelet transform is presented. The method is simple and iteration calculation free. Compared with dyadic wavelet transform, it possesses stronger abilities on signal processing and flexibility, therefore it is fit for fault signal analysis in power systems. Moreover, in this paper, digital filters and algorithms of microcomputer based protection in power systems based on non-dyadic wavelet transform are presented by using non-dyadic wavelet transform theory. It is of importance for reliability of microcomputer based protection in power systems.
