Application of high-temperature superconducting machines to direct drive renewable energy systems

O. Keysan,     University of Edinburgh, UK


After the discovery of high-temperature superconductors, superconducting machines became more feasible and have been applied to many applications such as ship propulsion systems. Superconducting machines are lighter, smaller and more efficient than conventional generators. In this chapter, mass of different direct drive generators systems have been compared. Direct drive superconducting generators have the potential to reduce the nacelle mass and the installation cost of a large offshore wind turbine. Ongoing commercial projects and the requirements for a reliable direct drive superconducting ...
