Abstract The main aim of the EU H2020 project EcoSwing was to demonstrate a technical readiness level 6–7 for high-temperature superconducting (HTS) technology operating in wind generator. To reach this goal, full-scale synchronous HTS generator successfully designed, built and field-tested 3.6 MW turbine. has rotor with 40 coils 1.4 m long. required >20 km coated conductor produced within project’s time schedule. All were tested prior assembly, >90% them behaving as expected. thus...
High temperature superconducting (HTS) technologies are expected to be a key enabler for lightweight and cost-effective direct-drive (DD) trains large wind turbines. This paper reports the designing basic experimental validation of world's first full-scale DD HTS generator demonstrated on commercial turbine. The has its rotor with an field winding working below 30 K, which is achieved by using off-the-shelf Gifford-McMahon cryocoolers. stator essentially conventional, except that armature...
High temperature superconducting (HTS) generators could enable a lightweight and cost-effective direct drive (DD) wind turbines with large power ratings. The EU-funded EcoSwing project successfully demonstrated the world's first full-scale MW-class HTS generator on commercial DD turbine. This paper focuses commissioning of campaigns, including rotor cool-down, excitation field winding, production generator, are presented in paper. In testing period, was grid-connected for more than 650 hours...
The EU-funded EcoSwing project addresses the world's first full-scale direct-drive (DD) high temperature superconducting (HTS) wind turbine generator. Before generator was installed on a commercial turbine, had been tested ground at Dynamic Nacelle Testing Laboratory (DyNaLab) in Fraunhofer Institute for Wind Energy Systems (IWES), serving as an experimental validation of design. This article is centered testing HTS generator, which includes corresponding tests validating generator's...
The goal of the EcoSwing project is to build world's first MW-scale superconducting generator for wind turbines. We report on main features machine's design; assembly its rotor, including cryostat and rotating GM-based cooling system; preliminary results ground-based test campaign that was executed prior upcoming field test.
The superconducting, heavy ion synchrotron SIS100 is the core of new FAIR facility at GSI, Darmstadt, Germany. Its unique design dedicated to acceleration intermediate charge state ions. Several technical approaches assure stabilization vacuum dynamics and minimization related beam loss. Beside high intensity ions, will accelerate all ions from Protons Uranium, in spite fact that superconducting magnets are used, shall be as flexible ramping cycling a normal conducting synchrotron.
Knowledge of the AC loss generated in a superconducting cable during variation magnetic field is essential when considering its use pulsed magnets. In round high-temperature (HTS) cables made from coated conductor (CC) tapes, hysteresis proportional to tape width. Then an effective measure for reducing division layer into parallel filaments. We investigated short models cables, containing different arrangements two layers 10 standard helically laid tapes. At amplitudes surpassing 0.1 T did...

The full energy exploitation of the Large Hadron Collider (LHC), a planned increase beam beyond present 6.5 TeV, will result in more demanding working conditions for superconducting dipoles and quadrupoles operating machine. It is hence crucial to analyze, understand, predict quench levels these magnets required values current generated magnetic fields. A one-dimensional multi-strand electro-thermal model has been developed analyze effect beam-losses heat deposition. Critical elements are...
