Non-Uniform Finite Difference Grid Approach for Modeling Grounding Systems

Original language description

This paper deals with a new way of modeling grounding systems using Higher-Order 2D and 3D Finite Difference Methods (HO-FDM) with non-uniform grid approach. In particular, the non-uniform finite difference grids used for modeling the geometry of grounded elements are presented. This numerical method examined to the rod electrode and grounding grid buried in the uniform and two-layer soils. Their solutions obtained by the iterative methods of Jacobi, Gauss{Seidel and Successive-Over-Relaxation (SOR) arepresented and discussed. The results show that the proposed method is acceptable and suitable for modeling and calculating any shape of grounding systems buried in uniform, two-layer and multilayer soils. Specially, the solution obtained by the non-uniform FD grid approach has high accuracy.
