Abstract

Kereta Rel Diesel Elektrik (KRDE) yang beroperasi di jaringan rel non listrik di daerah pedesaan sering menghadapi tantangan terkait tingkat kebisingan dan emisi karbon. Selain itu, KRDE memiliki dampak lingkungan yang signifikan karena tidak dilengkapi dengan fitur pengereman regeneratif. Untuk mengatasi masalah ini, sebuah inovasi KRDE yang terintegrasi dengan sistem baterai telah dikembangkan untuk secara efektif mengurangi konsumsi bahan bakar dan emisi gas rumah kaca. Studi ini menganalisis dampak strategi manajemen energi serta perhitungan kapasitas engine dan baterai pada kereta Hybrid Diesel-Baterai. Perhitungan kapasitas mesin dan baterai harus dilakukan dengan presisi tinggi untuk mencapai keseimbangan optimal antara berat sistem propulsi dan muatan penumpang, memastikan bahwa massa total tidak melebihi axle load yang dipasang. Daya maksimum yang mencakup daya traksi dan daya auxiliary dihitung berdasarkan gradient tercuram dan kecepatan operasional rute spesifik. Berdasarkan hasil simulasi kereta Hybrid dengan algoritma Equivalent Consumption Minimization Strategy (ECMS), ada lima kondisi pengendalian engine berdasarkan kapasitas SoC baterai traksi yang diusulkan berhasil mengurangi konsumsi bahan bakar sebesar 10,8% dibandingkan dengan KRDE. Selain itu, studi ini mengidentifikasi spesifikasi baterai yang sesuai berdasarkan jarak tempuh maksimum dan batasan ruang yang tersedia pada kereta. Simulasi menunjukkan bahwa dalam mode hybrid, untuk menempuh jarak pulang-pergi 700 km, sistem secara optimal memanfaatkan dua engine masing – masing berdaya 200 kW dan kapasitas baterai 250 kWh.

Diesel Electric Multiple Units (DEMUs) operating on non-electrified networks in rural areas often face challenges regarding noise levels and carbon emissions. Furthermore, standard DEMUs have a significant environmental impact due to the absence of regenerative braking. To solve these issues, an innovative standard DEMUs integrated with a battery system has been developed to effectively reduce fuel consumption and greenhouse gas emissions. This study analyzes the impact of energy management strategies and the calculation of engine and battery capacities in a Hybrid Diesel-Battery train. The calculation of engine and battery capacities must be conducted with high precision to achieve an optimal balance between the weight of the propulsion system and the passenger payload, ensuring that the total mass does not exceed the permissible axle load. The maximum load comprising both traction and auxiliary loads was calculated based on the steepest gradients and operational speeds of the specific route. Based on simulation results, five proposed energy management control conditions achieved a 10.8% reduction in fuel consumption compared to standard DEMUs. Additionally, the study identifies suitable battery specifications based on maximum travel distance and available spatial constraints on the train. Simulations demonstrate that in hybrid mode, covering a round trip distance of 700 km, the system optimally utilizes two 200 kW engines and a 250 kWh battery capacity.
