Description | Reliable electrical energy must be available on sites distributed along the railroad to guarantee the appropriate operation and safety. Unfortunately, a substantial portion of railroad tracks exist in remote areas or certain underground regions in which there is little electrical infrastructure. It seems that a reliable solution requires from different energy harvesters together with an appropriate storage and energy management to integrate the different energy sources using high power harvesting technologies. Choosing the best energy solution (generation & storage) for an specific application based on WSN will be the aim of this BB. |
Main output | An energy harvesting system to provide autonomy of operation of the ontrack communication equipement. The system will rely on high power harvesting technologies like these techniques based on the track vibrations but also other alternatives like solar panels. Another alternative that will be analysed is wireless energy transfer from the catenary railway to the secondary on track-side based on resonant inductive coupling; this can be a solution for High Speed railway where the catenary is electrified with AC. The appropriate design and integration of different sources is one of the critical issues that require a deep know-how in power converters and energy management technologies. This building block will be used in WP18 |
BB category | HW component |
Baseline | The power demanded by track-side infrastructures is about tens of watts or even 100W. This makes the energy harvesting quite complex since many of harvesting technologies, like piezoelectric and electromagnetic, are in the area of miliwatt to watt range. Therefore, there is a real need of high power energy harvesting (100W) and the corresponding energy management and storage to really achieve an appropriate deployment of these infrastructures along the whole rail system. There are promising solutions in the state of the art based on an electromagnetic energy harvester with mechanical motion that recover energy from the vibration track deflections induced by passing trains. These techniques are able to provide tens of watts but only when trains are passing. |
