Mathematical Modeling of a Diesel Electrical Locomotive

Abstract

Railway transportation has a huge share of energy consumption in the industry. The efficientpower consumption is the most important issue for the minimization of the cost of railwaytransportation. The control strategy for efficient power consumption is varying due to the type oflocomotive. Each type of locomotive needs its specific power model for this purpose.The range of the locomotives used in Turkey are full of diversity according to the type and size ofthe motor. In this research, DE 24000 type of locomotive is chosen for mathematically modelingof its required power under various load, speed, ramp, and curve conditions. Then a mathematicalequation is produced according to these values with Least Square Method. The optimum efficientworking point is found as 735.5-ton load and 38km/h speed with the aim of this produced equation
