摘要
介绍了小波变换的基本概念及其应用现状，从继电保护技术的观点出发讨论了小波变换的特点，小波变换的奇异性检测原理及其在继电保护技术发展中的作用。
The wavelet transform and its application are introduced.The distinguishing features and the singnlarity detection theary of wavelet transform associated with protective relaying technology are discussed.An example is given to verify the effectiveness of wavelet transform application to fault location based on travelling waves.
