Abstract
This study introduces electromagnetic design processes of 10-MW-Class High-temperature superconducting synchronous generator for wind Turbine. Superconducting generator can produce 5 times stronger magnetic field than
permanent magnet at least, which enables large scale wind turbine to function as a lighter, smaller and more highly efficient system. These processes are targeted for higher efficiency and shorter high temperature superconductor
(HTS) wires to fabricate 10 MW class superconducting synchronous generator. In this study, the design process was carried out through the following steps. First of all, the basic design models of the superconducting wind generator
were achieved from the two-dimensional (2D) numerical analysis. This step focuses on the design proposal that is possible to fabricate a lighter, smaller and more highly efficient generator while using a less HTS wires. Secondly, analysis model was designed by 3D CAD program for 3D electromagnetic field analysis. This step focuses on the 3D design of superconducting field coil with end shape and the calculation of the HTS wire length, weight and volume of generator. Last but not least, the two-dimensional design proposal was modified and optimized for manufacturing the superconducting generator by using 3D FEA (three-dimensional finite element analysis). This step focuses on the
optimization of the electrical output (induced electromotive force, losses, efficiency, etc.) and superconducting field coil parameters.
