CHALLENGE: Guarantee the energy supply of railway services.
WHAT IS THE RESEARCH? One of the main causes of loss of service is related to problems in the power supply (for example, due to cable theft). In addition, the characteristics between catenary and pantograph determine one of the main costs of maintenance both in the part embarked as in the part of infrastructure.
This is why Cormoran is being designed, to monitor the system, which would allow it to respond more quickly to unplanned events and therefore improve system availability. In addition to this, a system of conversion of high voltage energy from the catenary to low voltage is proposed to guarantee the operation of all the devices.
EXPECTED RESULTS: The technical solution proposed in this research project is to develop a compact system with the following functional modules:
- First, a modular DC / AC power supply capable of being connected to the railway system’s catenary to generate 230V rms single-phase alternating voltage necessary to power all auxiliary systems.
- Secondly, the system will be provided with local and global communication capabilities, that is, with the loads it is directly feeding, with the local control of the station and with a SCADA that can integrate all the systems Installed at different points in the railway network in order to monitor the electrical levels of the rail network as a whole.
- Thirdly, a system capable of detecting the theft of protection cable will be integrated taking advantage of the fact that the power converter will be permanently connected to earth.
- Fourthly, taking advantage of the fact that the power stage must measure the catenary voltage, the functionality of the measuring module will be expanded in order to be able to make snapshots of the evolution of the voltage in order to analyze the state of the contact Catenary-pantograph with on-line evaluation. Likewise, an algorithm will be developed that detects the passage of the pantograph in function of the evolution of the catenary voltage and that enables the capture of the temporal evolution of the voltage.
- Finally, the system will be equipped with ICT capabilities aimed at working as a distributed sensor node. In this way, all the information collected by the system will be sent telematically to a central monitoring and control unit so that the information can be collected in a SCADA
