✦ Synopsis
This paper presents the optimization via shape design of the ®eld coil using high temperature superconducting generator (HTSG). Response surface methodology (RSM) is applied to this optimizing process and well adapted to make an analytical model. In addition, it is easy to approach and ecient in seeking an optimal condition for a complex problem considering a lot of interaction of these design variables in an unknown system. I c in HTS materials is more sensitive to magnetic ®elds directed along the c axis of the unit cell (B c ) than to ®elds in the ab plane [J.F. Picard et al., IEEE Trans. Appl. Supercon. 9 (2) (1999) 535]. Thus, in the shape design of the HTS magnet, the design to reduce the maximum B c should be considered in order to maintain the stability and substantial improvement on the performance. The optimal condition of the magnet shape, which is used for the ®eld coil of HTSG, is obtained from the response surface made by RSM, and the eects of design variables related to the magnet are analyzed through the variance analysis. Moreover, the result of RSM is veri®ed by comparison with those experimental results.
