Modeling of laboratory microgrid

U radu je dan opis laboratorijske mikromreže koja je u fazi obnove i nadogradnje.Laboratorij prvenstveno služi studentima za izvođenje laboratorijskih vježbi i širenja znanja naučenih na predavanju.U radu je napravljen model hidroelektrane u MATLAB Simulinku.Hidroelektrane su složeni dinamički sustavi te je dan opis glavnih komponenti hidroelektrane.Prilikom modeliranja hidroelektrane potrebno je odabrati i pronaći zadovoljavajuće parametre te postaviti diferencijalne jednadžbe.U simlinku je napravljen model regulatora,turbine,cjevovoda i servo sustav pozicioniranja igle Peltonove turbine.Na kraju je napravljena simulacija modela za par slučajeva i prikazani su dobiveni rezultati koji pokazuju izlaznu mehaničku snagu turbine i ponašanje otvora turbine.In this paper laboratory microgrid, which is under renovation and upgrading, was presented.The laboratory is mostly used by students to preform laboratory excersises and to determine the knowledge learned in lectures.A model of the hydroelectric power plant was developed in MATLAB Simulink.Hydropower plants are complex dynamic systems and the main parts of hydropower plant are presented.When modeling the hydropower plant it is necessary to select and find right parameters for setting the differential equations.The model of regulator,turbine,pipeline and needle positioning of Pelton turbine were created in Simulink.Model simulation was made for some cases and the results were presented.Results show the output of the turbine mechanical power and the needle positioning
