Numerical analysis of mutual transient voltages in grounding systems of offshore wind farms

The paper illustrates a numerical procedure for the computation of mutual transient overvoltages transferred among typical grounding systems of wind turbines belonging to the same wind farm. We use a hybrid approach based on the circuit theory and the Method of Moments in the frequency domain. The transient response is obtained by means of the Inverse Fourier Transform efficiently computed trough a double-exponential formula.
