Wind energy is one of the fastest growing renewable energy sources for electricity generation over the past decade. The offshore installation of large-scale wind farms draws huge attention because of better wind profile. Direct drive synchronous wind turbine generators are now a global demand for light weight, compact, large scale wind turbine generators. Among various approaches in designing direct drive superconducting wind turbine generators, a comparatively new design (Figure 1) having both axial and radial air gaps between stator and superconducting rotor winding is selected for simulation work. It has the advantages of uniform stress and magnetic force around the circular coil. Elimination of gear box leads to light weight of the wind turbine generator. This paper deals with the simulation of magnetic flux distribution of stator and rotor coil of the same using the sliding mesh tool of COMSOL Multiphysics.
