KEYNOTE

2.3.2 Project 1.0 Ferrolinera: stage 2

This scenario considers the power of the Ferrolinera from the network of 3000 V DC traction.
A power electronic converter is required to be connected to the network and thus adapt the
voltage levels to the Ferrolinera.

2.3.3 Project 1.0 Ferrolinera: stage 3

The possibility of feeding the Ferrolinera from a team of storage of the energy generated in
braking of trains is incorporated. I.e., the charging system would have the possibility of power
from two sources (dual charge):

1. Directly from the network of 3,000 V DC (stage 2) traction
2. From a storage system

The introduction of a system that stores electrical energy (in this case, one that is generated
when trains hinder recovery and is not consumed by other existing in the corresponding
electrical canton trains) would compensate the needs generated by the Ferrolineras. In this
way, the storage system would provide the PB power Ferrolineras module. I.e., the power
of the Ferrolinera only from the traction network may cause a limitation to the power
supply of the trains, especially in periods of high traffic density.

The incorporation of a storage system would allow that in these cases the Ferrolinera feed
from such a system, there is no technical limitation to the power of trains while the system
has enough energy (in any case, the periods of maximum points should not be very long at
the time).

It should be noted that used in the previous functionality control system has been recently
patented by ADIF under application number 201130502 of the Spanish Patent and Trademark
Office.
