Kriging assisted determination of the optimal geometry and covering material for a bushing shield

This paper presents the principle of bushing shield size, position and its covering material determination, based on the optimization algorithm. An optimization procedure has been carried out using a differential evolution (DE) algorithm combined with a solver of the software tool EleFAnT, which is used for solving computationally expensive parametrically-written bushing FEM model. The goal of this research is to accelerate the optimization process, respectively to reduce the computational cost by introducing the Kriging metamodeling.
