Electric locomotive energy storage brake device

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 ].

How regenerative brake system is used in railway industry?

The energy can be stored either on-board the train or on storage devices on the track. This paper studies the energy storage technologies that are used in railway industry, mainly to improve the effectiveness of the regenerative brake system. This paper studies the three most widely used storage systems: batteries, supercapacitors and flywheel.

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.

Is regenerative braking energy fully utilized by traction trains?

To ensure that regenerative braking energy is fully utilized by traction trains in the whole railway power supply systems, an effective utilization scheme of the regenerative braking energy based on power regulation with a genetic algorithm (GA) is proposed in this paper.

Can energy storage devices improve regenerative brakes?

This paper reviews the application of energy storage devices used in railway systems for increasing the effectiveness of regenerative brakes. Three main storage devices are reviewed in this paper: batteries, supercapacitors and flywheels. Furthermore, two main challenges in application of energy storage systems are briefly discussed.

Is battery technology based on traction a suitable solution for shunting locomotives?

Battery technology based on traction is a very suitable solution for shunting locomotives due to the possibility of accumulating kinetic energy in the power supply. The energy efficiency of regenerative braking and the possibilities for efficient shunting in industrial plant were studied.
