Abstract:
V Slovenskem elektroenergetskem sistemu se za prenos električne energije v 400 kV omrežju uporablja vodnik Al/Je 490/65. Temperatura uporabljenega vodnika daljnovoda v obratovanju predstavlja enega izmed osnovnih mejnih pogojev za obratovanje daljnovoda. Dopustno segrevanje namreč ne sme preseči dovoljene vrednosti, ker vpliva na poslabšanje mehanskih lastnosti vodnika in povese. V diplomski nalogi je teoretično raziskana možnost povečanja tokovne obremenitve daljnovoda glede na spreminjanje zunanjih dejavnikov in sicer temperature okolice, vetra in sonca. Osredotočili smo se predvsem na ugotovitve CIGRE, ki so upoštevane v izračunih v programskem paketu MATLAB.

Title:
OVERHEAD POWER LINE CONDUCTOR TEMPERATURE DEPENDING ON CURRENT LOADING AND ENVIRONMENTAL IMPACTS
Abstract:
In the Slovenian 400 kV power system the conductor Al/Fe 490/65 is used for the transmission of electricity. Temperature of the overhead power line conductor during operation represents one of the basic operational limitation parameters for the overhead power line. Because of the negative impact on the mechanical parameters of the conductor and conductor sagging the conductor temperature must be under prescribed limits. Apart from that, the external parameters like ambient temperature, wind and solar radiation could influenced the conductor temperature. In this work the theoretical study of the possibility in the increasing current loading of the conductor, considering aforementioned external factors, is investigated. Mainly the findings of CIGRE working group are applied in the MATLAB program.
