| Abstract: | In the light of noise jamming, quantification error and frequency fluctuation of measured signals, a new method for phase difference measurement based on harmonic analysis and period tracking is proposed. The measurement theory and realization method is introduced. This method has been used in the generator experiment system, which proves to be a efficacious high - accuracy phase difference measurement method. |
