Optimization of Material and Structural Parameters of Nonlinear Stress Control Tubes in Cable Terminations

Abstract

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 reveals that the RSM is constructed efficiently and accurately by using the MLSM.
