In this study, a statistical feasibility analysis was performed using a universally valid equation model to determine how much of the power required by the YHT65000 series high-speed train sets can be supported by solar energy systems. Calculations were made with the necessary parameters obtained from the General Directorate of Meteorology, Turkey. To find the ratio to meet this power requirement, eight different Ankara-Eskişehir / Eskişehir-Ankara trips were used, and these trips were tested by 61 different distribution functions to find the optimum model for the probability density function for each trip. The selection of the best models among these different distribution functions is presented with their error rates. This study reveals the detailed statistical characteristics of the contribution of a solar energy system to be established to support the power requirement of the high-speed train line based on specific trips.

Bu çalışmada, YHT65000 serisi yüksek hızlı tren setlerinin ihtiyaç duyduğu gücün ne kadarının güneş enerjisi sistemleri ile desteklenebileceğini belirlemek için evrensel olarak geçerli bir denklem modeli kullanılarak istatistiksel bir fizibilite analizi yapılmıştır. Hesaplamalar Meteoroloji Genel Müdürlüğü'nden temin edilen gerekli parametreler ile yapılmıştır. Bu güç ihtiyacını karşılayacak oranı bulmak için sekiz farklı Ankara-Eskişehir / Eskişehir-Ankara seferi kullanılmış ve bu seferler 61 farklı dağılım fonksiyonu ile test edilerek her bir sefer için olasılık yoğunluk fonksiyonu için optimum model bulunmuştur. Bu farklı dağılım fonksiyonları arasından en iyi modellerin seçimi hata oranları ile birlikte sunulmuştur. Bu çalışma, yüksek hızlı tren hattının belirli seferlere dayalı güç ihtiyacını desteklemek için kurulacak bir güneş enerjisi sisteminin katkısının detaylı istatistiksel özelliklerini ortaya koymaktadır.
