ESTIMATION OF POWER-LINE FREQUENCY WITH LOW UNCERTAINTY FOR HIGH HARMONIC DISTORTION OF SIGNALS

Jan Blaska, Milos Sedlacek
  • Abstract:
    The paper compares four methods (zerocrossing with pre-filtration, integrated zero crossing, windowed and interpolated FFT, and dynamic parameter estimation with pre-filtration) of instantaneous power-line frequency estimation from the point-of-view of their sensitivity to higher-order harmonic content and to the additive noise and from the point-of-view of their response time. Comparison is based on computer simulations.
