Investigation into Multi-Phase Armature Windings for High-Temperature Superconducting Wind Turbine Generators

High-Temperature superconducting (HTS) generators are being considered as a competitive candidate in large direct-drive (DD) wind turbines because of their features of being lightweight and compact. Normally a large air gap is inevitable in partially HTS generators, sacrificing the torque producing capability. In this paper, multi-phase...

Performance of Multi-Layer and Stator-Shifting Fractional-Slot Concentrated Windings for Superconducting Wind Turbine Generators under Normal and Short-Circuit Operation Conditions

High temperature superconducting (HTS) generators are being considered for large offshore direct-drive (DD) wind turbines as they are expected to be lightweight and compact. However, short circuit torques of an HTS generator with integral-slot distributed windings (ISDWs) are too high for wind turbine constructions, mainly due to the large...

AC Loss Modeling of Superconducting Field Windings for a 10MW Wind Turbine Generator - an Analytical and Numerical Analysis

The total installed capacity of wind turbines is growing as society moves towards a more sustainable energy supply. With the integration of more wind turbines in the grid the price and reliability of future wind turbines are very important. One of the promising drive train topologies currently investigated is the direct drive superconducting...
