Simulation of the Grounding Grid by Coupling the Unidemensional Finite Element Method(FEM) and the Three-dimensional FEM
A novel method,which is based on electromagnetic field theory to calculate the current distribution in grounding grid is presented in this paper. The finite element method (FEM) is used to calculate the distribution of the fault current in the grounding grids. By using both the unidimensional units and the three-dimensional units in modeling the grounding grid and its surrounding soil, the performance of the real substation grounding grid can be analyzed. The current distribution in the grids as well as its distribution in the surrounding soil can be seen clearly. The accuracy of the calculation is improved significantly and both of the current flowing in the grids and the leakage current distributed in soil can be easily obtained under different condition.
