This paper provides an extensive analysis of ground systems and their effects on wind turbines. A typical arrangement of wind turbine ground system based on Grounding rings electrode is analyzed in this paper. The Grounding rings electrode are metal rings that make contact with the process liquid. The important issue of the effect of additional vertical and horizontal electrodes, respectively, has been addressed. The effect of the grounding wire placed in the cable fortress on the transient behavior is investigated in more detail. The mathematical formula in the field of frequencies is based on the theory of thin wire antennas and Pocklington's set of integro differential equations which is commonly mathematic formulas usage in this issue. In this analysis, the corresponding transient response is obtained using inverse Fourier transform (IFT). In the following, you will see that Pocklington's set of integro-differential equations is solved using the Galerkin-Bubnov indirect boundary element method (GB-IBEM) which using isoparametric elements.
