Summary: | In renewable energy-based generation sources a phase locked loop is one of
the most popular synchronization techniques. A rapid and precise grid
voltage phase and frequency estimation under a wide spectrum of possible
grid disturbances is its main objective. This paper compares popular grid
synchronization algorithms on grid voltage anomalies. The compared
algorithms are divided in three groups: without filtering, with filtering in
synchronous reference frame and with filtering in stationary reference
frame. The behaviour of the algorithms is tested in a laboratory, using
dSpace 1103 as a platform on which the algorithms are compiled and OMICRON
CMC 356 as a programmable grid voltage generator. The benchmarks conducted
in this paper include voltage sags, grid voltages harmonics, DC offset and
frequency step change. The obtained results show that there are significant
differences in tested PLL responses for some networks disturbances. [Projects of the Serbian Ministry of Education, Science and Technological Development, Grant no. III
