Evolution Strategy and Hermite polynomial approximation of the Finite Element Solution for Optimal Design of Transformer Insulation Structure

摘要

This paper presents a new optimal technique and its application in the optimal design of large power transformer insulation structure. Based on the finite element method and the sensitivity analysis technique, the Hermite polynomial approximation of the object function is constructed, the calculation of FE solutions and the object function are substituted by the calculation of polynomial approximation, so the time coat of optimization of electromagnetic devices decreases dramatically.
