Design and analysis of grounding systems for wind turbines using Finite element method

This paper proposes different designs of grounding systems for wind turbines. For each grounding system the maximum Electric field distribution is obtained. This paper introduces a new grounding system which decreases the electric field distribution in the grounding foundation used for wind turbines during the lightning strike. A performance comparison among proposed scheme is addressed. A detailed design procedure of the proposed grounding systems is also presented. To verify the analysis of proposed method, Simulation results have been presented in MATLAB and ANSYS using Finite element method.
