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 insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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.
