6 FAQs about [Electric locomotive energy storage brake]
How regenerative braking energy does an electric locomotive generate?
The AC–DC–AC electric locomotive generates a large amount of regenerative braking energy when braking, especially on large long downhill slopes [ 4 - 8 ]. In some cases, the regenerative braking energy generated by the locomotive recovers over a third of the total traction energy [ 8 ].
Do electric trains use regenerative braking?
Abstract—Electric rail transit systems are large consumers of energy. In trains with regenerative braking capability, a fraction of the energy used to power a train is regenerated during braking. This regenerated energy, if not properly captured, is typically dumped in the form of heat to avoid overvoltage.
How to maximize regenerative braking energy in railway line?
To maximize the utilization rate of the regenerative braking energy in the whole railway line, all the regenerative braking power should be properly regulated by RPCs and ETCs to the power arms that consume power. Then, the total traction power provided by the utility grid is the lowest.
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.
Does energy storage reduce regenerative braking energy use?
Actual reductions in energy use mainly depend on the number of start and stops as well as the traveled route . To analyze the effectiveness of energy storage for capturing a larger share of the regenerative braking energy, many parameters need to be considered.
Which energy storage source is used to perform recovery braking?
Embedded energy storage sources such as SCs or batteries are used to perform recovery braking. They are a more viable alternative to recover energy during braking. This option is similar to the one used in an application with a high-start/stop frequency such as elevators driven by synchronous machines [ 36, 37 ].
