【Abstract】 A fire-new plural list and interpolating windowed split-radix FFT (SRFFT) by reason of recent FFT algorithm’s deficiency is put forward. The algorithm can advance FFT algorithm’s precision. And then an analog analysis and an example are showed that SRFFT can measure truly every harmonic parameters. It has practical value for power system harmonic analysis and harmonic restraint.更多还原
