FASTGRID – Nákladovo efektívne obmedzovače skratových prúdov využívajúce pokročilé supravodivé pásky pre budúce vysokonapäťové jednosmerne rozvodné siete
Cost effective FCL using advanced superconducting tapes for future HVDC grids
Program: Horizon 2020
Project leader: doc. Ing. Gömöry Fedor DrSc.
Annotation: Sustainability of energy systems goes through high penetration of renewable energy with huge volumes of electricity to transmit over long distances. The most advanced solution is the HVDC Supergrid. But fault currents remain an issue even if DC circuit breakers have emerged. These are not satisfying, whereas Superconducting Fault Current Limiters (SCFCLs) using REBCO tapes bring an attractive solution. SCFCLs have already proved their outstanding performances in MVAC systems, with a few commercial devices in service. However, present REBCO conductors cannot be readily used at very high voltages: the electrical field under current limitation is too low and leads to too long tapes and high cost. FASTGRID aims to improve and modify the REBCO conductor, in particular its shunt, in order to significantly enhance (2 to 3 times) the electric field and so the economical SCFCL attractiveness. A commercial tape will be upgraded to reach a higher critical current and enhanced homogeneity as compared to today’s standards. For safer and better operation, the tape’s normal zone propagation velocity will be increased by at least a factor of 10 using the patented current flow diverter concept. The shunt surface will also be functionalized to boost the thermal exchanges with coolant. This advanced conductor will be used in a smart DC SCFCL module (1 kA, 50 kV). This one will include new functionalities and will be designed as sub-element of a real VDC device. In parallel to this main line of work, developments will be carried out on a promising breakthrough path: ultra high electric field tapes based on sapphire substrates. FASTGRID will bring this to the next levels of technology readiness. In conclusion, FASTGRID project aims at improving significantly existing REBCO conductor architecture to make SCFCLs economically attractive for HVDC Supergrids. However, availability of such an advanced conductor will have an impact on virtually all other applications of HTS tapes.

Vysokoteplotná supravodivá cievka pre motory elektrických a hybridných lietadiel
High temperature superconducting coils in motors for electric and hybrid aircrafts
Program: SRDA
Project leader: Mgr. Pardo Enric PhD.
Annotation: Full superconducting electric motors are very promising to provide therequired power density to enablecommercial hybrid and electric airplanes. These can reduce emissions by75 % in CO2 and 90 % in NOx, followingthe ACARE Flightpath 2050 targets of the European Union. Superconductingmotors can also be applied to cleanersea or sweet water transport. In spite of the extensive research in thearea, the electro-magnetic and electro-thermal properties of superconducting coils in the motor magneticenvironment remain largely unknown, partiallybecause of the lack of measurements of the relevant temperatures(between 20-40 K) and modeling methods forfull superconducting motors.The aim of this project is to gain this understanding and develop numerical modeling methods to enable the design of future superconducting motors. These methods will be compared to experiments in the relevant temperature range for motor applications.

MAPKO – Magnetické plášte z kompozitov supravodič/feromagnetikum
Magnetic cloaks from superconductor/ferromagnet composites
Program: SRDA
Project leader: doc. Ing. Gömöry Fedor DrSc.
Annotation: Realization of a magnetic cloak allowing to hide objects from being observed by a magnetic detector enables the experimental study of several fundamental problems of electromagnetism as well as the searching for innovative solutions of practical problems of magnetic field shielding and shaping. Main aim of the project is the development of methods for design and realization of magnetic cloaks that would provide the possibility to investigate these topics. Basic property we will pursue is the magnetic invisibility when a detector placed outside the cloak will not notice the cloak itself nor a “magnetic cargo” it would contain. Theoretical predictions for reaching perfect invisibility assume unrealistic properties of the used materials and work with ideal and simple shapes without any limitation of dimensions. That is why an important part of the project will be the search and testing of new numerical modelling methods able to include these substantial aspects of real objects. With help of these novel methods we plan to demonstrate the 99% perfection in magnetic invisibility at frequencies from DC to 1000 Hz. Our research could help to reach the following goals: a) Creation of space for experiments in biology shielding the Earth magnetic field as well as that produced in urban environment. Room temperature cylindrical space with at least 50 mm diameter and 150 mm height should allow easy sample exchange and manipulation. b) Design and manufacturing of the cloak for magnetic fields in the 0.1 T range with the volume exceeding 1000 cm3 for the purpose of protecting a sensitive electronic circuitry or e.g. formation of working space for DC arc welding in vicinity of electrical machines generating the stray field at this level. c) Investigation of force exerted on the cloak by a non-uniform magnetic field, in particular the possibility of a magnetic propulsion with help of controlling the magnetic moment of the superconductor/ferromagnet composite.
