Transmission line models for different line lenght

U ovom završnom radu predstavljen je problem modela dalekovoda. Prije svega, pojašnjeni su glavi parametri dalekovoda kako bi se lakše razumio princip rada istih. Nakon toga, sve je smješteno u kontekst dvoprilaza. U ovisnosti o duljini dalekovoda, prikazana su tri modela dalekovoda – dugi, srednji i kratki te su dane jednadžbe da svaki pojedini. Sve su jednadžbe prikazane u matričnom obliku i kao takve su se koristile pri rješavanju zadataka. Za matematički proračun korišten je računalni program MATLab.In this paper is presented the problem of transmission line models. First of all, the main transmission line parameters are explained so it could be easier to understand the work principle. After, it is all placed in the context of two-port representation. Depending on the transmission line length, are discussed three models of transmission lines – long, medium and short, and are given the equations for each one. All equations are given in matrix form and as such are used for solving numerical problems. For math calculation is used the computer package MATLab
