Diesel Electric Locomotive Architectures Based On The Type Of Current Regenerative braking is a feature in some diesel electric locomotives that allows the locomotive to recover energy during braking and store it for later use. when the locomotive applies brakes, the traction motors switch from acting as motors to generators, converting the kinetic energy of the moving train into electrical energy . The paper has proposed a backward looking quasi static model of a conventional 1.6 mw heavy haul diesel electric locomotive utilized by the national railway company, based on the known locomotive power train parameters, such as diesel engine rated power and output power throttle control, and electric transmission type. The electric transmission system of diesel electric hybrid shunting locomotive is mainly composed of diesel generator set, on board power battery pack, rectifier, bidirectional dc dc converter, traction inverter, auxiliary converter, mechanical drive device and so on [3]. its system structure is shown in fig. 1. fig. 1. The braking energy in diesel electric locomotives is typically wasted into resistors. a more energy efficient way is to store and recycle such energy. thus, this article proposes a multiport power conversion system as the core of a hybrid energy storage system, based on lithium ion (li ion) batteries and supercapacitors (scs). in such configuration, scs act as a buffer against large magnitudes.

When the diesel engine runs, it drives the generator through a shaft. the generator produces alternating current (ac) electricity. this electricity is then rectified into direct current (dc) before being sent to the traction motors. the efficiency of the generator is vital for the overall performance of the locomotive. 2.2 system structure of diesel electric hybrid shunting locomotive the power flow of diesel electric hybrid shunting locomotive is shown in fig. 2, where the red arrow indicates that energy can flow in both directions. in the figure, p es is the output power of the on board power battery pack after passing through the bidirectional dc dc.
