Abstract

Prilikom odabira adekvatne pozicije za izgradnju novog dalekovoda, u obzir se moraju uzeti razni parametri koji utječu na funkcionalnost samog dalekovoda, ali i na procjenu rizika od zadiranja dalekovoda u okolnu vegetaciju u koju se planira postaviti. Tehnički problemi u izvedbi novih trasa dalekovoda su rješivi stručnim znanjem, no pri izgradnji dalekovoda se javlja i problem utjecaja na okoliš, okolne elemente pored kojih bi se gradio dalekovod, itd.
Kako bi se razvoj dalekovoda poboljšao i olakšao, stvorila se potreba za izradom programa koji će prikazati željeni dalekovod u realnoj dimenziji na željenom mjestu, odnosno za prikazom njegovog 3D modela. 3D-vizualizacija znatno doprinosi razumijevanju odnosa između nadzemnog visokonaponskog voda i okolnih objekata u prostoru te je takav program bio cilj ovog diplomskog rada.
U ovom diplomskom radu, razvijene su razne metode za generiranje kompletnog stupa, bilo zateznog, bilo nosivog, različitih izvedbi oblika glave stupa (jela, dvostruka jela, dunav, bačva, mačka, Y), kao i vodiča i zaštitnih užeta.
Metode su razvijene modularno tako da je lako generirati novi oblik glave stupa i slično, a pisane su u programskom jeziku Java. Izvršavanjem metoda dobivaju se modeli u formatu COLLADA. Programski se stvara i KML datoteka u kojoj se nalaze svi podaci dalekovoda te modeli koji se prikazuju u njemu. Svaki model ima svoju zemljopisnu širinu i dužinu, rotaciju s obzirom na z os, nadmorsku visinu i lokaciju gdje se taj model stvarno nalazi. KML datoteku je moguće učitati u Google Earth program i na taj način vizualno prikazati sve modelirane dijelove dalekovoda.

Abstract (english)

When choosing an adequate position for the construction of a new transmission line, various parameters must be taken into account that affect the functionality of the transmission line itself, but also the assessment of the risk of the transmission line interfering with the surrounding vegetation. Technical problems in the construction of new transmission line routes can be solved with professional knowledge, but during the construction of the transmission line there is also the problem of environmental impact, the surrounding elements next to which the transmission line would be built, etc.
In order to improve and facilitate the development of the transmission line, there was a need to create a program that will display the desired transmission line in a real dimension in the desired location, in other words - to display its 3D model. 3D-visualization significantly contributes to the understanding of the relationship between the overhead high-voltage line and the surrounding objects in space, and such a program was the goal of this thesis.
In this thesis, various methods have been developed for generating a complete transmission line pole, either tension or load-bearing, different versions of the shape of the transmission line pole head (jela, dvostruka jela, dunav, bačva, mačka, Y) as well as lines and protection ropes.
The methods are developed modularly so that it is easy to generate a new transmission line pole head shape for example, and are written in the Java programming language. Executing the methods produces models in the COLLADA format. The program also creates a KML file which contains all the data of the transmission line and the models that are displayed in it. Each model has its own latitude and longitude, rotation with respect to the z axis, altitude, and location where that model is actually located. The KML file can be opened in the Google Earth program and thus visually display all modeled parts of the transmission line.
