Abstract: The high temperature superconducting (HTS) wind power generator requires current leads for transferring current from room temperature to the cryogenic environment, which causes conduction heat load. Therefore, the current lead should be designed for minimizing the heat load of the cryogenic system of the HTS wind power generator. This paper presents a design of a current lead for the large scale superconducting wind power generator. The heat loss of the current leads are modeled and calculated mathematically. Thermal characteristics of the HTS module coil with designed current leads were analyzed using a 3D finite element method (FEM) program. The analysis results were compared with the calculation results. The calculation and FEM simulation results have a good agreement. The design and the thermal analysis results of the current leads for HTS module coil can effectively be utilized to develop the large scale superconducting wind power generator.
