High Temperature Superconducting

Due to the high current density in 77K, the high temperature superconducting facilities are expected to improve the efficient in power transmission. Superconducting facilities electromagnetic design is highly dependent on the characteristic of the superconducting tape. As a result, the comparison of the effect of different tape in electromagnetic design should be studied. In this paper, several facilities model are used as example to analyze the effect of different tape utilization. The result shows in different application conditions, or, specific benefits are considered, there is a specific tape will be the best choice.

Compared with the conventional transformer, high temperature superconducting (HTS) transformer can effectively improve the efficiency of the system. The current lead of HTS transformer is a main part that leads to leak out heat, and its thermal leakage loss greatly influents the performance of cryogenic system. So it is important to design and optimize the current lead. In this paper, the current lead of a 50MVA HTS transformer is designed, depended on the calculated conclusion of temperature field with FEM method, the optimization of the current lead is carried out to decrease heat losses.
