Abstract (en)
Focus of the Doctoral dissertation are algorithms for grid voltage
synchronization based on phase-locked loop. These algorithms are
examined in context of grid-tie inverters for renewable energy
sources. At the start, detailed mathematical description of three-phase
voltage system is provided. Mathematical transformations of threephase
system (Clarke and Park transformation and transfer of phase
voltage into line voltages) are examined through Bode diagrams.
Bode diagram of symmetrical components decomposition is also
provided. In the next chapter, detailed review of synchronization
methods between two elements in electrical power system is
provided. Methods that were used and that are used are described for
grid voltage synchronization. Next, the most popular three phase
phase-locked loop algorithms for grid-tie inverters are examined in
detail. A way tuning based on multicriteria graphic using modern
simulation software is proposed. Subsequently, two new algorithms
for grid-tie inverters are presented along with considerations required
for free parameters tuning. Next, experimental validation of presented
algorithms is done, along with two new algorithms. Details of digital
implementation and details of experiment are provided. At the end,
conclusion is provided in line with presented results.

“Data exchange” service offers individual users metadata transfer in several different formats. Citation formats are offered for transfers in texts as for the transfer into internet pages. Citation formats include permanent links that guarantee access to cited sources. For use are commonly structured metadata schemes : Dublin Core xml and ETUB-MS xml, local adaptation of international ETD-MS scheme intended for use in academic documents.
