Şehiriçi raylı sistemlerde EN standartları ve iş güvenliği kısıtlamalarından dolayı DC gerilim tercih edilmektedir. Şehiriçi enerji şebekesinden elde edilen gerilim sinusoidal dalga şekline sahip olduğu için DC gerilim elektrifikasyon sisteminde bulunan doğrultucu sistemi ile ayrıca elde edilmektedir. Enerji hattından gelen gerilim orta gerilim seviyesinde olduğu için istasyon trafo merkezlerinde kurulu transformatörler yardımıyla doğrultucu sisteminin ihtiyacı olan seviyeye dönüşüm gerçekleştirilmektedir. Doğrultucu sisteminden elde edilen DC gerilim yardımıyla katener hattına gerekli olan enerji iletimi sağlanarak araçlara güç temin edilmektedir. Bu çalışmada DC beslemeli bir raylı sistem hattında kullanılan doğrultucu parametrelerinin cer gücü sistemine etkisi araştırılarak sistem analiz edilmiştir. Çalışma için 12 km uzunluğa sahip ve 10 istasyondan oluşan bir raylı sistem hattı kullanılmıştır. Elde edilen sonuçlar üzerinden karşılaştırma yapılarak doğrultucu sistemi için optimal tasarım esasları ile ilgili önerilerde bulunulmuştur.

Investigation of Rectifier Parameters for Traction Power in DC Feed Rail Systems

Öz

DC voltage is preferred in urban rail systems due to EN standards and occupational safety restrictions. Since the voltage obtained from the urban energy network has a sinusoidal waveform, the DC voltage is also obtained by the rectifier system in the electrification system. Since the voltage coming from the power line is at medium voltage level, the transformer is transformed to the level required by the rectifier system with the help of transformers installed in the substation substations. With the help of the DC voltage obtained from the rectifier system, the vehicles are supplied with the necessary energy transmission to the catenary line. In this study, the effect of rectifier parameters used in a DC feed rail system on traction power system was investigated and the system was analyzed. For the study, a rail system line with a length of 12 km and consisting of 10 stations was used. By comparing the results obtained, suggestions for optimal design principles for rectifier system were made.
