Simulation and experimental results of the use of
three SPLL (Software PLL) that differ by the method of the
detection of symmetrical grid voltage sequences (positive and
negative ones) in case of an unsymmetrical grid voltage system
with harmonics and under usual disturbances and parameter
changes of the grid are presented. The function of the DSC
(Delayed Signal Cancellation) based SPLL with
was experimentally verified under different grid voltage
disturbances with satisfactory results.
