System Research in Energy| Zusammenfassung: | The article proposes a method for refining the fundamental frequency of a three-phase grid in dynamics to determine the phase shift between phases, based on the analysis of the phase characteristic of the voltage of each phase obtained through a discrete Hilbert transform. The proposed method makes it possible to determine the fundamental frequency with an absolute error of no more than 1.46 mHz, and the phase shift between phases with a relative error of no more than ±0.11443 %. |
