Electromagnetic Simulations of a Fully Superconducting 10-MW-Class Wind Turbine Generator

An electromagnetic design study of a 10-MW-class synchronous generator that has both the field and armature windings superconducting is presented. The field winding is assumed to be made of YBCO tapes, whereas multifilament MgB

wires are considered for the armature winding. The proposed design is analyzed using a finite-element-based simulation tool. The results obtained show that a higher output voltage, and hence higher power levels, can be achieved compared with the more common arrangement where the field winding is superconducting whereas the armature winding is made of copper. Moreover, the proposed structure weighs less and has better flux density distribution within the armature.
