DONES-FLUX, for an efficient and safe particle accelerator
Edair Technologies works hand in hand with the Universidad de Sevilla and the Universidad de Extremadura to test an experimental SMES system
DONES-FLUX directs technological research focused on improving the operational efficiency of large scientific facilities like IFMIF-DONES by optimizing the different flows of energy, matter, and information. The consortium, composed of Hi-Iberia, ASE Optics Europe, DEM Barcelona, EDAIR Technologies, Leading Metal-Mechanic Solutions, and SUPRASYS, is developing this project within the framework of the 2022 CDTI Missions. Their work makes scientific work more efficient and sustainable.
One of the main goals of the project is to develop an energy damping system that can handle the load peaks typical of a particle accelerator. To this end, Edairtec, in collaboration with the Universidad de Seville and the Universidad de Extremadura, is implementing an innovative SMES system.
EXPERIENCE serving INNOVATION
Edairtec's role in the DONES-FLUX project highlights its commitment to technological and scientific advancement. Its integrating role in the development of the energy damping system goes hand in hand with its experience. In this way, it channels the development of power electronics by the Universidad de Seville, and the SMES system in collaboration with Suprasys and the Universidad de Extremadura.
As an engineering company that integrates energy systems, Edairtec has executed similar technology projects in the past. Thanks to DONES-FLUX, this technology is moving from air transport to science.
SMES system, the best way to damp a pulsed current
The SMES (Superconducting Magnetic Energy System) essentially consists of a coil made of superconducting material through which an electric current flows. Its low resistance makes it ideal for storing and delivering large amounts of energy. This, combined with its long lifespan, makes it a suitable device for conditioning an electrical grid with constant pulses. The introduction of the SMES is an innovative solution that allows for greater efficiency and durability of energy management systems. The consortium aims to improve response times to less than 10 milliseconds for the compensation of energy fluctuations.
For the development of the DONES-FLUX SMES, Edairtec and Suprasys have had the technical support of the Universidad de Extremadura. Specifically, the "Benito Mahedero" Group for Electrical Applications of Superconductors has a trajectory of more than 20 years of research and experimentation to improve power systems using SMES technology.
SMES demonstrator, how to simulate the conditions of a particle accelerator
The demonstrator, designed by the POWERUS research group at the Universidad de Sevilla, is a bidirectional power converter. Its architecture is similar to an H-bridge, but the semiconductors have been replaced by diodes.
Between the two diodes, the SMES system is connected and will be tested by inputting charges and discharges. The system has been designed to operate at a maximum voltage of 800V and a current of 6A. The peak power will be 2800W and it will operate at a frequency of just 1kHz. This high switching frequency is possible thanks to the use of Schottky diodes and MOSFET semiconductors.
The central control system acts as the brain of the system, managing measurements, digital inputs and outputs, and executing control algorithms. Likewise, the semiconductor management system executes commands from the central control that expose the SMES to different scenarios.
All hands on deck!
Edairtec is applying the theoretical knowledge obtained in DONES-FLUX to the local control systems developed for the VATIAC pre-commercial public procurement, offered by the CDTI and IFMIF-DONES Spain.
The SMES system integrated into the damping system converts VATIAC into a cutting-edge and innovative technological validator.
This project, with file number MIP-20221017, has been subsidized by the CDTI - Center for the Development of Industrial Technology through the "CDTI Missions" program call of the year 2022 and is supported by the Ministry of Science and Innovation.
