摘要
小波变换是在傅里叶变换的基础上发展起来的一种时-频域分析方法,通过利用小波变换技术对电能质量问题进行了研究,建立了小波快速算法,并运用该方法实现了对电能质量扰动的检测和定位.
Wavelet transform is developed in Fourier transform based on a time-frequency analysis method. Through wavelet transform technology of power quality problems, an extensive research on the power quality is conducted with some results, and wavelet fast calculation method is set up, through which the power quality disturbance can be detected and located.
