  • PHASE LOCK LOOP WITH CASCADE TRACKING FILTERS FOR SYNCHRONIZING AN ELECTRIC GRID
    Publication number: 20150381187
    Abstract: Present embodiments relate to a method for synchronizing an electric grid. The method includes receiving a phase voltage of the electric grid. The method further includes determining one or more disturbance frequencies in the phase voltage via a plurality of sequential tracking filters, wherein each of the plurality of tracking filters corresponds to a harmonic of the received phase voltage. The method further includes removing the disturbance frequencies components sequentially to produce a minimally distorted frequency, and performing a PLL operation on the clean frequency to determine a phase angle of the frequency.
