摘要
为了实现对电力系统谐波的检测,采用了傅里叶变换与小波变换相结合的方法,通过在实例中对比二者的不同特点,将二者的优点结合起来,应用到具体信号的分析中,经过MATLAB仿真,得到各次谐波的有效信息。从而表明,此方法可以对电力系统中的各次谐波进行检测和分析。
In order to achieve inspection of power system harmonics, an approach of combining Fourier transform and wavelet transform is designed in this paper. Through compares the different characteristics in practical example of the two＇s that the combination of both can be applied to the analysis of specific signal. The useful information of each harmonic according to the results of MATLAB simulation are detained. It is demonstrated that the method can be used for inspection and analysis of power system harmonics.
