6 FAQs about [Locomotive energy storage brake]

Why do electric locomotives use traction batteries?

The batteries are charges from electric trains during the regenerative braking of electric locomotives. Locomotives operating in the traction mode use less electrical energy from traction substation I and substation II because a part of energy is supplied by the energy storage batteries.

How do trains generate regenerative braking energy?

Trains can unlimitedly generate regenerative braking energy when capacitors SCB block and conventional storage batteries CB operate. The regenerative braking energy is consumed by the train itself and by other powering trains. Excessive power is stored in the battery. The charging voltage in the batteries is higher than that of the substation.

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 ].

How much energy does a regenerative braking system store?

Unlike inverters, the energy is retained within the system, preventing losses that typically occur in transformers and rectifiers. Some verification tests revealed that ESSs could store approximately 21 % of the total energy generated from regenerative braking.
