Abstract

New developments of the wind power technologies open a wide future in the next decade. One of such developments is the novel high temperature superconducting (HTS) generators using in the wind turbine, which can greatly enhance the power output stability while sharply cut down the volume and weight. A 100 kW model generator is proposed and the racetrack excitation coil for it is designed and tested considering the stability against current pulses. The magnetic field distribution in the coil is numerically evaluated and measured via a BSCCO practice coil tested in liquid Nitrogen. The electromagnetic design and wind techniques of the coil are also discussed.
