Abstract
U ovom diplomskom radu opisan je ispravljač i kakve utjecaje ima na izmjeničnu pojnu mrežu zbog nelinearnosti komponenata. Opisuje se način rada transformatora te mogućnosti spajanja primarnog i sekundarnog namota. Uz pomoć različitih spojeva primara i sekundara definiraju se 4 grupe spoja za koje će se napraviti analiza rada. Korištenjem Lucas-Nulle didaktičko-multimedijalne opreme, njegovih eksperimenalnih kartica i programskog paketa Labsoft vrše se mjerenja za Yy0, Yd0, Yy6 i Yy10 grupu spoja transformatora. Uz pomoć virtualnog spektralnog analizatora koji je dio programskog paketa Labsoft-a mjeri se harmonijski sadržaj fazne struje sekundara transformatora. Dan je postupak izračuna THD fazne struje sekundara transformatora za zvijezda i trokut spoj. Napravljena je detaljna analiza utjecaja grupe spoja i satnog broja na THD fazne struje sekundara transformatora.
Abstract (english)
This thesis describes the rectifier and what effects it has on the alternating supply network due to the nonlinearity of the components. The mode of operation of the transformer and the possibility of connecting the primary and secondary windings are described. With the help of different primary and secondary compounds, 4 groups of compounds are defined for which a work analysis will be performed. Using Lucas-Nulle didactic-multimedia equipment, its experimental cards and the Labsoft software package, measurements are performed for the Yy0, Yd0, Yy6 and Yy10 group of the transformer connection. With the help of a virtual spectrum analyzer that is part of the Labosft software package, measurements of the harmonic content of the phase current of the transformer secondary were performed. The procedure for calculating the THD phase current of a secondary transformer for a star and triangle junction is given. A detailed analysis of the influence of the connection group and the hour number on the THD phase currents of the transformer secondary was made.
