Design of Multiple Motor Synchronization and Energy Management System in TCDD DE24000 and DE36000 Type Diesel-Electric Genset Locomotives

Öz

This study comprehensively examines the electrical synchronization of multiple engine-generator sets, power electronics topologies, and energy management system (EMS) design in diesel-electric genset locomotives. The original contribution is proposing a detailed system architecture for utilizing the indigenously developed 1200 HP (883 kW) V8 diesel engine by TÜBİTAK-RUTE in 2-engine (DE24000, total 1,766 kW) and 3-engine (DE36000, total 2,649 kW) configurations. The research addresses 750–1,200V common DC bus synchronization, passive diode rectifier vs. active front-end converter alternatives, rule-based and optimization-based EMS strategies, and functional safety requirements (EN 50126/50128/50129, SIL 2). Comparative analysis of NRE 3GS21B (182 units, 40%+ fuel savings), TRAXX DE ME Class 245 (137 units, ~10% savings), and CRRC HXN6 hybrid (~20% savings) reveals that the 3-engine configuration offers the optimal balance with 33%/67%/100% power granularity and 67% fault redundancy. Optimization-based EMS strategies provide 5–27% additional fuel savings overrule-based approaches, while SiC semiconductor technology can improve traction system efficiency by up to 35%.

TCDD DE24000 ve DE36000 tipi Dizel-Elektrik Genset Lokomotiflerde Çoklu Motor Senkronizasyonu ve Enerji Yönetim Sistemi Tasarımı

Öz

Bu çalışma, dizel-elektrik genset lokomotiflerde çoklu motor-jeneratör setlerinin elektriksel senkronizasyonu, güç elektroniği topolojileri ve enerji yönetim sistemi (EYS) tasarımını kapsamlı bir şekilde incelemektedir. Çalışmanın özgün katkısı, TÜBİTAK-RUTE tarafından geliştirilen 1200 BG (883 kW) gücündeki V8 özgün dizel motorun 2 adetli (DE24000, toplam 1766 kW) ve 3 adetli (DE36000, toplam 2649 kW) çoklu motor konfigürasyonlarında kullanılması için detaylı bir sistem mimarisi önermesidir. Araştırmada; 750-1200V ortak DC bara mimarisi üzerinden jeneratör senkronizasyonu, pasif diyot doğrultucu (%30 THD, 0,85-0,95 güç faktörü) ve aktif ön uç (AFE) dönüştürücü (<%5 THD, birime yakın güç faktörü, ~2 kat maliyet) alternatifleri, IGBT cer invertör konfigürasyonları, kural tabanlı ve optimizasyon tabanlı enerji yönetim stratejileri ile fonksiyonel güvenlik gereksinimleri (EN 50126/50128/50129, SIL 2) detaylı olarak ele alınmaktadır. NRE 3GS21B (3 motorlu, 182 adet üretilmiş, %40+ yakıt tasarrufu), Bombardier TRAXX DE ME Class 245 (4 motorlu, 137 adet, ~%10 tasarruf) ve CRRC HXN6 hibrit lokomotif (~%20 tasarruf, 180 ton/yıl yakıt azaltımı) deneyimleri karşılaştırmalı olarak analiz edilmiştir. Optimizasyon tabanlı EYS stratejilerinin kural tabanlı yaklaşımlara kıyasla %5-27 ek yakıt tasarrufu potansiyeli sunduğu, SiC yarı iletken teknolojisinin cer sistem verimini %35'e varan oranlarda artırabildiği belirlenmiştir. Sonuçlar, 3 motorlu konfigürasyonun (DE36000) kontrol karmaşıklığı, %33/%67/%100 güç granülaritesi ve %67 arıza yedekliliği açısından en uygun dengeyi sunduğunu ortaya koymaktadır.
