Power system harmonic detection based on cubic spline function and Rife-vincent self-convolution window interpolation FFT algorithm
When using the Fast Fourier Transform(FFT) to perform harmonic analysis on power systems, due to asynchronous sampling and data truncation, fence effect and spectrum leakage will occur, and accurate harmonic parameters cannot be obtained. In order to improve the accuracy of harmonic detection of asy...
