6 FAQs about [Belmopan locomotive energy storage brake]
Can regenerative braking improve energy recovery in diesel-electric freight trains?
The present work evaluates the application of regenerative braking for energy recovery in diesel-electric freight trains to increase efficiency and to improve decarbonization. The energy from regenerative braking has to be stored onboard when the track is not electrified. Different technologies of energy recovery are presented and discussed.
Can a dual-mode locomotive increase energy recovery during braking?
The global energy reduction is around 1.1% compared with the second EMS and 12.8% without energy recovering. These results show a real opportunity to increase the energy recovered during braking. A dual-mode locomotive has a common drivetrain that operates on not- and electrified tracks.
Can a dual-mode hybrid locomotive manage energy consumption?
This study proposes an energy management strategy (EMS) for a dual-mode hybrid locomotive equipped with a fuel cell, supercapacitors, and batteries, and intermittent access to an electrified overhead catenary. It is inspired by the Ragone plot and does not consider information or predictions of future load consumption.
What is the braking energy dissipated on the on-board resistors?
The braking energy dissipated on the on-board resistors is constantly 0% since no voltage limiter is included in this first analysis. Fig. 24 shows the voltage peak due to regenerative braking, as a function of the braking request and of the position between two adjacent Electrical Sub-Stations where the train begins the braking manoeuvre.
Are fuel cell locomotives a good alternative to diesel engines?
Considering the high cost of the network electrification, this is a good compromise to reduce energy consumption in rail transport [ 1 ]. In this regard, fuel cell (FC) locomotives are considered as a great alternative to moving away from locomotives using diesel engines [ 2 - 8 ].
Is Bellman-Ford algorithm feasible for electric traction motors?
It is feasible for locomotives with electric traction motors, both electric and diesel-electric. With the purpose of maximizing the regenerated energy, the Bellman–Ford algorithm has been used in [ 8] to optimize the braking and speed of a train.
