To do so, transmission capacity is of significant importance. As the building of new overhead lines is an expensive and long-term investment, increasing the transmission capacities of existing lines is an unavoidable necessity. The transmission capacity of overhead power lines is commonly determined by limitations on the conductor's temperature, characterized by its ampacity. The conductor's temperature, and therefore the ampacity, is dependent on weather conditions. This fact enables increasing the transmission capacity according to calculations based on current weather conditions and forecasts, as opposed to static and conservative values. This paper discusses the application of different standards and comparison of results for transmission capacity value, with particular reference to Croatian legislation on transmission overhead power lines. Calculation of sensitivity on input parameters is also examined because of the changes in the weather that change transmission capacity. As an extreme case of unfavourable weather conditions, an example is given of transmission capacity value trends during the hottest recorded day Croatia. The conclusion is that increases of the transmission capacity on particular power lines is possible but, for the safe and secure operation of the transmission grid, a seasonal regime of operation or ampacity zones depending on the time of the year could be made"},{"@xml:lang":"sl","#text":"Odpiranje trga z električno energijo spremlja vstop novih udeležencev na trg, kateri morajo izpolniti določene zahteve, da trg z električno energijo lahko nemoteno deluje ob upoštevanju prenosne zmogljivosti prenosnega omrežja. Gradnja novih daljnovodov je finančno zahtevna ter predstavlja dolgoročne naložbe in je žal neizogibna zaradi želenega povečanja prenosnih zmogljivosti obstoječih daljnovodov. Maksimalna tokovna zmogljivost in temperatura vodnikov omejuje zmogljivost prenosa daljnovodov. To dejstvo omogoča povečati prenosno zmogljivost v skladu z izračuni, ki temeljijo na trenutnih vremenskih razmerah in napovedih, v nasprotju s statičnimi in klasičnimi vrednostmi. Ta članek obravnava uporabo različnih standardov in primerja rezultate vrednosti prenosnih zmogljivosti prenosnih daljnovodov z upoštevanjem hrvaške zakonodaje. Analiziran je vremenski vpliv na vhodne parametre, kar vpliva na prenosne zmogljivosti in posledično na občutljivost izračuna. Kot ekstremni primer neugodnega vremenskega vpliva je v analizi zajet tudi najbolj vroč dan na območju hrvaškega prenosnega sistema. V zaključku dela je predstavljeno, da je možno povečati zmogljivosti prenosnega omrežja oziroma posameznih daljnovodov, vendar za varno in zanesljivo obratovanje omrežja je potrebno upoštevati sezonski režim delovanja"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-GQKB65WQ","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-GQKB65WQ"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-GQKB65WQ/7e2420d5-436e-4dbb-a09a-3092995f7a67/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Mariboru, Fakulteta za energetiko"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-GQKB65WQ/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-GQKB65WQ"}}}}
