| Abstract |
In this paper, an optimal design was performed to improve the power density and specific power of a superconducting generator for 10MW-class actively shielded wind turbine using the response surface method (RSM). The objective functions of optimal design for reducing the weight of the generator were selected as perpendicular magnetic flux density, output power, and terminal voltage. The design variables were selected as three variables: field coil aperture, shield coil aperture and superconducting coil pitch (between shield and field aperture), which have a great influence on the objective function. After that, optimal design points were derived within the optimal region, and verification was performed through finite element analysis(FEM). |
