Abstract

The mathematical models proposed in the
literature are used to determine the grounding resistance value for electrical
installations. These models are mathematical expressions that change according
to grounding type and the mechanical properties of the grounding system
elements. Besides, the inclusion of nonlinear terms is another important issue
in the modeling studies. For the modeling of nonlinear systems and the analysis
of the faults that may occur, the finite element analysis (FEA) approach
provides realistic results. In the present study, the simulation of a grid
fault that may occur in the grounding system of a sample wind turbine (WT) is
modeled by 2D electrostatic solver in FEA software. The simulation results
prove that the findings are similar to the realistic faults in the grounding
system.
