The needs for high power offshore wind turbine are increasing continuously together with the rapid development of the wind power market.Superconductivity may be the only technology to scale wind turbines up to 10 MW and beyond by reduction of the nacelle mass.The SUPerconducting Reliable lightweight And more POWERful offshore wind turbine (SUPRAPOWER),an EU FP7 founded research project,are developing an innovative superconducting 10 MW class offshore wind turbine.The superconducting generator is a direct drive salient poles synchronous machine.The filed coils in the wind turbine generator are made of superconductors based on MgB2 tapes.
