摘要

In order to fast solve the electric field inverse problem for high voltage electric apparatus, a new algorithm called reduced basis finite element method (RBFEM) was proposed in this paper. The reduced basis technology and the finite element method were integrated effectively. Firstly, the principle of RBFEM was analyzed. Secondly, as an optimization design example for gas insulated switchgear (GIS) arc-quenching chamber, the fast optimization algorithm implementation process based on RBFEM program, including modeling, setting objective function and design variable, optimization strategy given, sample strategy, sub-domain decomposition and Determination of sample parameters N, were introduced in detail. Finally, electric field distribution of the optimized contact shape was solved by using ANSYS and the solution was compared by using RBFEM. The computational result shows that the computational error is 1.3%, which verified the effectiveness of the proposed algorithm.
