Abstract
U ovom radu su izrađeni modeli transformatora za proračune prenesenih prenapona i istraženi su faktori koji utječu na visinu prenesenog napona. U prvom dijelu rada prikazan je teorijski dio o transformatorima i opis programskog paketa EMTP. Također su opisani spojevi namota, natpisna pločica transformatora, oznake stezaljki i funkcija blok transformatora u prijenosnoj mreži. U drugom dijelu rada su modelirana dva BCTRAN modela transformatora u EMTP programu. BCTRAN model transformatora proširen kapacitetima je moguće koristiti za više frekvencije. Najprije su modelirana tri jednofazna transformatora od kojih je svaki za svoju fazu, a zatim je modeliran trofazni transformator. Rezultati su prikazani u grafičkom obliku. U slučaju da nije instaliran odvodnik prenapona na 220 kV strani, ugrožena je niženaponska strana blok transformatora tj. preneseni prenaponi su veći od izolacijskog nivoa. Transformatori se štite odvodnikom prenapona.
Abstract (english)
In this paper, models of transformers used for calculations of transmitted overvoltages are developed and the factors influencing the height of transmitted voltage are investigated. In the first part of the paper a theoretical part about transformers and a description of the EMTP software package are presented. The winding connections, the transformer nameplate, the terminal markings and the function of the block transformer in the transmission network are also described. In the second part of the paper, two BCTRAN models of transformers in the EMTP program are formed. BCTRAN model of transformer with expanded capacities can be used for higher frequencies. First, three single-phase transformers were formed, each for its own phase, and after that a three-phase transformer was formed. The results are presented in graphical form. If there is the case that the surge arrester is not installed on the 220 kV side, the low voltage side of the block transformer would be endangered, which means that the transmitted overvoltages are higher than the insulation level. Transformers are protected by surge arresters.
