Накратко на български
Свръхпроводниците от магнезиев борид ($\text{MgB}_2$) се анализират чрез компютърни модели и тестове, за да се намалят енергийните загуби при работа на кабели и трансформатори. Това помага за разработването на по-ефективни проводници, които да се използват в индустриални електроенергийни системи.

Final Activity Report Summary - MODELMGB2 (Modelling, characterization and development of MgB2 superconductors for AC power applications)
The objectives of MODELMGB2 have been all fulfilled, and are listed in the following: Acquisition of knowledge and skills by the host organisation in numerical modelling techniques of HTS materials with the finite-element method (FEM). Advanced training of host staff in 2D / 3D FEM modelling and simulation of MgB2 conductors, including development of new Jc(B) and n(B) models. Studying the AC losses in multifilamentary MgB2 wires and tapes and the ways for loss optimisation in different applications by means of intensive FEM simulations. Evaluating the operating conditions and magnetic field effects in MgB2 superconducting devices, such as cables, transformers, and fault-current limiters. Upgrading the experimental system of the host for AC loss measurements with transport current up to 800 A with / without external magnetic field in the range 4.2 - 30 K. Performing system calibration, I-V data acquisition for DC characterisation, and AC loss measurements of the manufactured conductors with the electrical measurement technique. Design and development of novel low-loss MgB2 conductors for AC power applications. Thanks to these achievements, modelling and experimental tools to analyse and optimise the architecture of MgB2-based superconducting wires produced in industrial quantities have been now developed. Particular regard to AC-loss optimisation has given the required feedback to the wire production team within the Company. A multifilamentary conductor with special Titanium-based sheath has been therefore developed. This conductor is expected to represent soon the basis for AC applications of superconducting wires in applications.

Цел на проекта
One of the high-temperature super-conductor (HTS) with greatest potential for large-scale industrial applications is the recently discovered (in 2001) Magnesium Diboride (MgB2). The introduction of novel MgB2-based electrical devices in the existing and future European power networks will increase their efficiency, power quality and the optimisation of available resources. At this stage, however, further RTD efforts on MgB2 conductor development are required, especially towards power applications, for which the AC losses are of primary concern. The main goal of this project is the development of novel low-loss MgB2 wires and tapes with improved properties for AC power applications. For this purpose advanced 2D and 3D numerical methods will be used for conductor modelling in different operating conditions.The AC loss mechanisms will be investigated and possible ways for loss minimization will be studied by finite-element method simulations. The optimal geometries and conductor configurations (in terms of lowest AC losses) will be used for the design of novel conductors with improved AC loss performance, produced in long lengths. In addition, experimental characterization of the conductors will be performed, consisting of measurements of the critical current in magnetic field, as well as of the transport current and magnetization AC losses. This is a multidisciplinary project, involving crucial aspects of materials science, experimental physics, and electrical engineering. The transfer of knowledge and skills in numerical modelling, and the acquired advanced experimental know-how, will allow the host organization to consolidate its international collaboration and reinforce its position as a leading European manufacturer of long-length MgB2 conductors for large scale applications, such as super-conducting fault-current limiters, transformers, and cables, which are expected to reach around 2010-2012 an important market share in the electric power industry.
