Abstract
Türkiye’de, Büyükşehirlerdeki trafik sorununa çözüm olarak raylı sistemler gibi kendisineayrılmış yol üzerinde hareket eden toplu taşıma araçları tercih edilmektedir. Raylı sistemler,yüksek taşıma kapasitesi ve düşük enerji tüketimi nedeniyle gelişmiş ülkelerde en çok tercihedilen toplu taşıma türüdür. Artan yolculuk talebiyle doğru orantılı olarak enerji ihtiyacı ve güçkaybında da bir artış vardır. Bundan dolayı raylı sistemlerin proje tasarım aşamasındaki güç akışıanalizi kritik önem arz etmektedir. Güç akış analizi ile raylı sistemlerde kullanılacak ekipmanlar(kablo kesiti, OG hücresi, CER transformatör gücü, yük ayırıcı ve kesiciler vb) ve buekipmanların teknik özellikleri belirlenir. Bu tezde M5 Üsküdar – Yamanevler Sürücüsüz metrohattında güç akış analizi, alternatif işletme senaryoları için yapılmıştır. Bu çalışmada ETAP(Elektriksel Geçici Rejim ve Analiz yazılımı kullanılarak elde edilen benzetimsonuçlarına göre, güvenli ve sürdürülebilir güç akışı için en kötü durumlar gözönüne alınarakçözümler sunulmuştur.
In Turkey, as a solution to traffic problems in metropolitan areas, public transportation thattravels on a guided way such as rail systems is preferred. Railway transport is the most preferredtype of public transport, as well as its high carrying capacity and low-cost energy consumptionin developed countries. Therefore, the demand for rail transport has been increasingsignificantly over the years in proportion to increasing urban population. There is also anincrease in energy consumption and accordingly, power loss in proportion to increasingdemand. Therefore, the power flow analysis of the rail systems in the project design phase iscritical. By means of AC power flow analysis, equipment to be used in rail systems (cable crosssection,MV switchgear, transformer power, load separator, and breakers, etc.), and thecharacteristics of these equipment are determined. In this thesis, power flow analysis isperformed on M5 Üsküdar – Yamanevler driverless metro line. According to the simulationresults obtained by using ETAP (Electrical Transient and Analysis Program) software, solutionsare provided considering the worst cases for the safe and sustainable power flow.
