Abstract
This paper presents topology optimization of HTS
racetrack coils for large HTS synchronous machines. The topology
optimization is used to acquire optimal coil designs for the excitation
system of 3 T HTS machines. Several tapes are evaluated and
the optimization results are discussed.
The optimization algorithm is formulated to minimize the cost
for the coils wound with one type of HTS as well as multiple HTS
types. It could also be used to minimize other parameters, e.g. space
required for the coils. The results are inherently highly dependent
on the HTS properties, which at 20 K seem to be in favor of the 1 G
tape. The maximal HTS savings achieved allowing multiple current
supplies in the excitation system are investigated and estimated to
be in the range of 50% for highly nonlinear J-B dependence HTS
tapes.
