In grid interactive power
converter applications, phase locked loop (PLL) algorithms are very important
to realize grid synchronization. The performance of PLL should not be affected
by adverse conditions such as voltage unbalance, harmonics, frequency and phase
changes. Otherwise, synchronization errors occur between the grid interactive inverter
and the grid. In this paper, two different PLL algorithms are simulated by
modeling under MATLAB/Simulink. The performances of the PLLs are comparatively
presented under four different grid conditions such as balanced, unbalanced,
harmonics and variable frequency. In this study, synchronous reference
frame-PLL (SRF-PLL) and decoupled double synchronous reference frame-PLL
(DDSRF-PLL) which are mostly used, state-of-arts and effective PLL algorithms
are analyzed by modeling in grid synchronization applications. It has also been
demonstrated the positive and negative aspects of the PLLs based on the
obtained results.
