Electromagnetic field analysis of standard and compact transmission lines tower by using finite element method

V Sloveniji in drugod po svetu je na podeželju veliko razpršene gradnje, kar je največja ovira pri načrtovanju trase visokonapetostnega daljnovoda, saj morajo biti upoštevani varnostni odmiki od objektov. Zato je zelo pomembno, da dosežemo čim ožje vplivno območje elektromagnetnega sevanja. V diplomskem delu smo potrdili, da kompaktne izvedbe daljnovodnih stebrov res prispevajo k zmanjšanju vplivnega področja, so pa te izvedbe danes zanimive tudi iz drugih razlogov. Za določitev dopustnega vplivnega področja smo izhajali iz Uredbe o elektromagnetnem sevanju v naravnem in življenjskem okolju Republike Slovenije. Izračun elektromagnetnega polja smo izvedli z inženirskim programskim paketom EleFAnT po principu metode končnih elementov v dvorazsežnem prostoru.In Slovenia, as elsewhere in the world, there are a lot of dispersed settlements in the countryside, which is the biggest limitation when planning new transmission lines’ routes, because ensuring safety distances from buildings must be taken into consideration. Therefore it is very important to obtain a narrow zone of influence regarding electromagnetic radiation around high-voltage transmission lines. In this diploma work we confirmed that a compact tower for power lines really contributes to reducing the zone of influence around the transmission lines and also has other interesting features and advantages. In order to determine an acceptable zone of influence we took into account the regulations regarding electromagnetic radiation within natural and living environments, as issued by the Republic of Slovenia. Electromagnetic field calculation was done using the EleFAnT, engineering software package on the principle of the finite element method in two dimensions
