This paper proposed a design methodology of cold-dielectric (CD) high temperature superconducting (HTS) power transmission cables. The methodology covers the effects of the electrical and mechanical properties of both insulation materials and HTS tapes; the dimensions of the conductor layers, insulation layers, shield layers, the annular cooling gap and the cryostat. The selection of insulation materials...
The non-uniform AC current distribution among the multi-layer conductors in a high-temperature superconducting (HTS) cable reduces the current capacity and increases the AC loss. In this paper, Particle swarm optimization coupled with differential evolution operator (DEPSO) has been applied in structural optimization of HTS cables. While the existence of fluctuation in design variables or operation...
The nonuniform ac current distribution among the multilayer conductors in a high-temperature superconducting (HTS) cable reduces the current capacity and increases the ac loss. Various numerical simulation techniques and optimization methods have been applied in structural optimization of HTS cables. While the existence of fluctuation in design variables or operation conditions has a great influence...
The response surface method (RSM) is applied in the parameter optimization of nonlinear stress control tubes in power cable terminations. A local approximation method, called moving least square method (MLSM), is adopted to reduce the approximation errors. The electric field intensity is calculated by the transient finite element method. A comparison of the parameters before and after optimization...
