Abstract :
Discrete/fast Fourier transform (D/FFT) has been widely used for diagnosis of power equipment. D/FFT inevitably has the inherent drawbacks. As one of the methods to overcome the drawbacks, interpolated discrete/fast Fourier transform (IpD/FFT) has been proposed. IpD/FFT has higher accuracy. We proposed recursive interpolated discrete/fast Fourier transform (R-IpD/FFT) for on-line calculation. In this paper, we discuss the phase compensation of R-IpD/FFT.
