Abstract

Ovaj rad sadrži kratak pregled teorije i postupak kojim se izračunava induktivitet nadzemnih vodova. Opisan je postupak izračuna induktiviteta pomoću obuhvaćenih i ulančanih magnetskih tokova. Pomoću metode srednjih geometrijskih udaljenosti pokazano je kako se prepliću vodovi s dva trofazna sustava na istom stupu. Zatim je u trećem poglavlju pokazan postupak proračuna induktiviteta s utjecajem zemlje odnosno Carsonov izvod. Pomoću prethodnih razmatranja izveden je matrični račun za izračunavanje induktiviteta nultog, direktnog i inverznog sustava. Praktični dio rada primjenjuje prethodna teoretska razmatranja na proračunu impedancije odnosno induktiviteta 2x400 kV voda u slučaju kad je vod neprepleten, djelomično i potpuno prepleten.

Abstract (english)

This thesis contains a short review of theory and methods used to calculate inductance of double overhead lines. The procedure for calculating the inductance using magnetic flux linkage is described. By using method of geometric mean distance it is explained how to transpose conductors of two three-phase systems on the same pylon. Carsons formulas are used to calculate inductance with the influence of the ground. Direct, inverse and zero system impedance is calculated using matrix calculus. In the practical part of the thesis inductance of double overhead lines is calculated in case when conductor is untransposed, half cycle transposed and completely transposed.
