title = "A novel interpolated FFT algorithm based on convolution window",
abstract = "FFT algorithm is widely used in power system harmonic analysis. But in traditional FFT, big harmonic measurement error appeared caused by spectral leakage & hurdle effect while unsynchronized sampling. In this paper, an improved algorithm is introduced, a FFT with convolution windows and interpolated value is proposed to improve measuring accuracy of frequency, harmonic phase and amplitude through additional windows & interpolated corrective value. Guyuan Power Grid parameters of Ningxia Province were used into simulation analysis, the verification between simulation results and actual test reports show that: Improved algorithm effectively enhance the accuracy of harmonic measurement with very limited spectral leakages and hurdle effects, and meanwhile simplified the whole operation.",
