| Abstract: | A framework of the power quality analyzer is showed in this paper. After discussing the impact of nonsynchronous sampling, this paper briefly introduces its realizing method. In order to improve the accuracy of calculation, FFT algorithm based on window function and interpolation is used to analyze the harmonic of power systems. Finally, the realization of the algorithm is described in detail. |
