Hybrid locomotive
Our company took part in modernization and refurbishment project of a narrow gauge diesel-electric locomotive. During modernization the locomotive got a brand new vehicle control and traction system. The new diesel-electric traction system was supplemented with a traction battery group which got location between diesel-generator and traction systems.
Komplett villamos keretBesides the extreme traction power requests the diesel engine, thanks for the installed traction battery group, can be worked in optimal operating point, which results lower fuel consumption. Further the kinetic energy can be recuperated into batteries during electro-dynamic braking.
In frame of project our company accomplished the following tasks:
- design and dimensioning of electric traction system of loco (calculations, simulations, electric schemes),
- dimensioning of Li based traction battery group,
- design and manufacturing of traction battery containers,
- carry out the design and manufacturing processes of control and traction current boxes based on our electric schemes,
- implementation of whole electric system and liquid cooling system of traction equipment by our experts,
- design and code of system operational software,
- put into operation and commissioning of loco.
During modernization we have used reliable, tried, manufactured in serial electric components that are suitable for operation in harsh railway circumstances which provides economical and safe operation of vehicle.
The loco is suitable for pure electric operation as well, which is useful during workshop movements and direction changing at headstations where the loco has to be switched to other end of train.
