Abstract

Energy efficiency studies are becoming widespread in all systems where electrical energy is used. This situation is also important in rail public transportation systems that require great power. In particular, the electricity consumption of subway and trams used in mega-cities reaches a considerable level. For example, Istanbul urban public transportation system consumes about 300 million kWh of energy per year. The energy distribution consumed differs in tram and subway lines. Taking into account the amount of energy consumed, the technical and economic benefits of the efforts to increase energy efficiency are becoming more significant. In this study, DC load flow analysis was performed for a sample area selected from the Istanbul urban public transportation system. Technical and economic evaluations have been carried out by modeling using RAILSIM software, depending on line parallelism and train load. The effects of the results obtained from technical and economic efficiency analyzes for different working situations are presented.

Özet

Elektrik enerjisinin kullanıldığı bütün sistemlerde enerji verimliliği çalışmaları yaygınlaşmaktadır. Bu durum büyük güç gerektirenraylı toplu taşıma sistemlerinde de önem arz etmektedir. Özellikle, mega kentlerde kullanılan metro ve tramvayların elektrik tüketimiazımsanmayacak seviyelere ulaşmaktadır. Örneğin İstanbul raylı toplu taşıma sistemi, yılda yaklaşık 300 milyon kWh enerjitüketmektedir. Tüketilen enerji dağılımları tramvay ve metro hatlarında farklılık göstermektedir. Tüketilen enerji miktarları dikkatealındığında, enerji verimliliğini arttırma çalışmalarının sağlayacağı teknik ve ekonomik faydalar daha da anlamlı hale gelmektedir.Bu çalışmada, İstanbul şehir içi raylı ulaşım sisteminden seçilen örnek bir bölge için DC yük akışı analizleri gerçekleştirilmiştir.RAILSIM yazılımı kullanılarak yapılan modelleme ile hat paralelleme ve tren yüküne bağlı olarak teknik ve ekonomikdeğerlendirmeler gerçekleştirilmiştir. Farklı çalışma durumları için gerçekleştirilen teknik ve ekonomik verimlilik analizlerinden eldeedilen sonuçların etkileri sunulmuştur.
