Abstract
U ovom radu je korak po korak opisana sinteza PLL sustava za mjerenje frekvencije. U prvom poglavlju objašnjen je osnovni koncept PLL sustava, PLL sustav za energetske signale te je takav sustav u programskom paketu Matlab/Simulink testiran na idealne uvjete u mreži i uvjete nesimetrije. Nakon otkrivanja nesavršenosti takvog, osnovnog PLL modela, sustav je razvijan kroz modifikacije algoritma. Prvo je uveden DSOGI filter, objašnjen je princip rada te realizacija u Simulinku. Nakon testiranja DSOGI filtera i ne baš zadovoljavajućih odziva, opisan je princip rastavljanja na simetrične komponente te njihova implementacija u Simulink modelu PLL sustava. Nakon toga objašnjen je princip na kojim radi FIR filter te način na koji se projektira, a zatim je u sustav i dodan FIR filter. Nakon zadovoljavajućih odziva, napravljena je usporedba sustava s i bez FIR filtera, te se sustav s FIR filterom pokazao kao optimalan za dovoljno širok raspon frekvencija. U posljednjem poglavlju objašnjena je izvedba mjernog sustava na PLC-u. Na kraju je, na osnovu svih provedenih testova i adaptacija izveden zaključak.
Abstract (english)
In this thesis, synthesis of PLL system for frequency measuring was described. In the first chapter were described basic concepts of PLL system, PLL system for grid signals and such system was tested in Matlab/Simulink in symmetric and asymmetric grid conditions. After detection some imperfections of such, basic PLL model, system was further developed through modifications of algorithm. Firstly, DSOGI filter was introduced, its work principle and Simulink realization were described. After testing system with DSOGI filter and not so good system responses, principle of symmetrical components was explained and implemented in Simulink model. Lastly, work principle and projecting of FIR filter was explained, and it was added to system. After satisfying responses, comparison between system with FIR filter and system without FIR filter was made, and system with FIR filter proved to be optimal. At the last chapter implementation on programmable logic controller was explained. At the end, conclusion was derived, based on conducted tests and adaptations.
