Abstract

In DC railways, the traction power supply
voltage provided by the electrification system gives the power it needs. Energy
is aimed to be of high quality while providing this power. The vehicle’s
performance is influenced when the voltage supplied for the vehicle performance
is in certain limits. This value is affected by voltage drop on the line. In
this study, the determination of the minimum vehicle voltage in a railway line
with 1500 V DC supply in relation to the vehicle performance data was
investigated. .The artificial intelligence methods adaptive neuro-fuzzy
inference system (ANFIS) and support vector machines (SVM) were applied. The
performance data of Sultangazi-Arnavutkoy metro line were used in the study.
Ideal results were obtained with the calculations.

1500 V DC Beslemeli Bir Metro Hattında Minimum Araç İşletme Geriliminin Performans Verilerine Bağlı Olarak Belirlenmesi

Abstract

DC
beslemeli metro hatlarında elektrifikasyon sistemi tarafından sağlanan cer gücü
besleme gerilimi vasıtasıyla aracın ihtiyacı olan güç sağlanmaktadır. Güç temini
sağlanırken enerjinin kaliteli olması hedeflenir. Hat için sağlanan gerilimin
belirli sınırlar dahilinde olması aracın performansını etkilemektedir. Hatta
oluşan gerilim düşümüne bağlı olarak bu değer etkilenmektedir. Bu çalışmada
1500 V DC beslemeli bir metro hattında minimum araç geriliminin araç performans
verilerine bağlı olarak belirlenmesi incelenmiştir. Çalışma için yapay zeka
tekniklerinden olan Uyarlamalı Sinirsel Bulanık Çıkarım Sistemi (ANFIS) ve
Destek Vektör Makinaları (SVM) yöntemleri tercih edilmiştir.  Çalışma için Sultangazi-Arnavutköy hattına ait
bir grup performans verisi kullanılmıştır. Yapılan hesaplamalarla ideal
sonuçlar elde edilmiştir.
