Yüksek gerilim iletkenleri, enerji talebinde göz önünde bulundurulması gereken en önemli unsurlardandır. Günümüzde elektrik enerjisine karşı artan talep, güç sistemlerinde kayıp artışı, hat kapasitelerinin yetersizliği, sehim vb. sorunları meydana getirmektedir. Bu sorunları çözmenin birkaç yolu bulunmaktadır. Çözümlerden biri ise, günümüzde kullanılan konvansiyonel iletkenleri, Yüksek Sıcaklık Düşük Sehimli (HTLS) iletkenlerle değiştirerek, iletkenlerde sarkma (sehim) miktarını minimuma indirmek ve daha yüksek sıcaklıklarda çalışabilen HTLS iletkenler üzerinden daha fazla akım iletimi sağlanarak, mevcut durumdan daha fazla akım taşıma kapasitesi elde etmeyi amaçlamaktadır. Fakat bu işlemi yapmadan önce bir de bunun maliyet tarafı ele alınmalıdır. Bu çalışmada, konvansiyonel iletkenler ile HTLS iletkenler teknik ve ekonomik açıdan incelenmiştir. Elde edilen sonuçlara baktığımızda da HTLS iletkenlerin teknik ve maliyet açısından birçok konuda konvansiyonel iletkenlere göre daha avantajlı olduğu görülmüştür.

TECHNOECONOMIC ANALYSIS OF HTLS CONDUCTORS

Öz

High voltage conductors are one of the most important elements to be considered in energy demand. The demand of electrical energy increases day by day, unfortunately it creates some problems (power loss, insufficient line capacities, sag etc.) on power systems. However, there is some methods to solve these problems. One of these methods is to minimize the amount of sag in the conductors by replacing the conventional conductors used with High Temperature Low Sag (HTLS) conductors. In addition, it aims to obtain more current carrying capacity than the current situation by providing more current transmission over HTLS conductors that can operate at higher temperatures. But, the installation of new line costs should be considered before decide to do it. In this study, conventional conductors and HTLS conductors are examined in terms of technical and economic terms. In terms of the results obtained, HTLS conductors have been found to be more advantageous in terms of technical and cost than conventional conductors.
