Field optimization of three dimensional high voltage equipment

The goal of finding an optimal electric field strength distribution for arbitrary three dimensional problems can be achieved by utilizing a parametric CAD modelling system that needs to be coupled with a three dimensional electric field calculation program. These components are to be linked with a numerical optimization algorithm. The package obtained from these three components is then able to automatically optimize arbitrary three dimensional field problems in high voltage engineering. Since one of the bottlenecks in the optimization process mentioned above is the three dimensional electric field calculation, several methods for accelerating this process have been investigated. One of these methods, the parallelization of the numerical field calculation, will be explained in this paper. A practical example which has been optimized using the tools described in this paper will be introduced.
