文中针对暂态电能质量问题，主要在电能质量扰动检测方面做了一些工作，在小波变换局部模极大值理论的基础上，针对连续小波变换的计算量大，存在较大冗余的缺点，采用二进小波变换对电能质量扰动进行检测。小波变换的局部模极大值对应信号的突变点，可以用来检测电能质量扰动。

In view of transient power quality problems, this paper has done some researches on power quality disturb- ance detection. Because the calculation quantity and redundancy of continuous wavelet transform is big, binary wavelet transform is adopted to detect power quality disturbance based on wavelet transform local modulus maximum theory, which corresponding to the mutation point of signal.
