Description (srp)

Focus of the Doctoral dissertation are algorithms for grid voltagesynchronization based on phase-locked loop. These algorithms areexamined in context of grid-tie inverters for renewable energysources. At the start, detailed mathematical description of three-phasevoltage system is provided. Mathematical transformations of threephasesystem (Clarke and Park transformation and transfer of phasevoltage into line voltages) are examined through Bode diagrams.Bode diagram of symmetrical components decomposition is alsoprovided. In the next chapter, detailed review of synchronizationmethods between two elements in electrical power system isprovided. Methods that were used and that are used are described forgrid voltage synchronization. Next, the most popular three phasephase-locked loop algorithms for grid-tie inverters are examined indetail. A way tuning based on multicriteria graphic using modernsimulation software is proposed. Subsequently, two new algorithmsfor grid-tie inverters are presented along with considerations requiredfor free parameters tuning. Next, experimental validation of presentedalgorithms is done, along with two new algorithms. Details of digitalimplementation and details of experiment are provided. At the end,conclusion is provided in line with presented results.
