202 Optimization of Magnetic Field Problem using Response Surface Method

In this paper, a magnetic field optimization problem of a reactor is shown. Reactors are widely used as a part of electric power system. The noise arised from vibration of them which is caused by magnetic force is required to be suppressed. In order to evaluate the noise, the sound pressure is calculated by coupling analysis of magnetic field and structure. Optimization system for minimization the sound pressure using response surface method was developed in this study. Because of the nonlinearity of the response, RBF network was applied to the approximation model. The usefulness of the system was confirmed by the result of an example.
