Abstract
Osnove karateristike prijenosnih mreža su dugi nadzemni vodovi koji povezuju velika elektroenergetska postrojenja. Konstante voda su raspodijeljene kroz dužinu cijelog voda, što znači da se naponske i strujne prilike mijenjaju i prostorno, a ne isključivo u vremenu. Jednadžbe koje opisuju naponske i strujne prilike u ovisnosti o udaljenosti zovu se prijenosne jednadžbe, dobiju se uz pomoću jednadžbi dobivenih pomoću Kirchoffovog i Ohmovog zakona. Četveropol je sklop s dva para prilaza, namijenjen za prijenos električne energije. U praksi se elementi četveropola voda raspoređuju po π i T shemi. Nadomjesni modeli voda bitni su kako bi se ustanovila razlika određenih vrijednosti na promjenjivim duljinama vodova. Dva osnova madomjesna modela su π i T modeli. Na kraju se, u primjeru, realizira korištenje konstanti voda te se njihovim izračunom dolazi do računa za prijenosne jednadžbe voda, četveropole, nadomjesne π i T modele. U primjeru se preko tablica i grafova analiziraju vrijednosti.
Abstract (english)
The basics of transmission system characteristics are long overhead lines that connect large power structures. Power line constants are distributed throught the length of the line, which means that voltage and electric current conditions change both spatially and not exclusively over time.The equations describing the voltage and electric current conditions as a function of distance are called transmission equations and are obtained using the equations obtained by Kirchoff's and Ohm's law. The quadrupole is an assembly with two pairs of entrances, designed for electricity transfer. In practice, the elements of quadrupole line are distributed according to the π and T schemes. Power line models replacement schematic are essential to determine the difference between certain values at variable line lengths. The two basics of the model are π and T models. In the end, in the example, the use of power line constants is realized, and by their calculation the calculations for the transmission equations, quadrilaterals, replacement π and T models are calculated. In the example, the values created are analyzed through tables and graphs.
