FDTD Calculation of Transient Electromagnetic Fields in the Grounding System of Wind Towers Due to Direct Lightning Strikes

چکیده
Lightning protection system (LPS) for wind power generation has become an important public issue due to greatly increasing installations of wind turbines (WTs) worldwide. Grounding system is one of the most important components required for appropriate LPS for WTs. Although the finite-difference time-domain (FDTD) method for solving Maxwell`s equations is difficult for computing earth potential rise (EPR) and transient grounding resistance (TGR), this method is used in this paper to compute EPR and TGR for different configurations of the grounding system of WTs because FDTD method can efficiently deal with the three-dimensional geometrical configurations of an investigated structure unlike electromagnetic transient programs (EMTP).

متن کاملElectromagnetic Field Due to Lightning Strikes to Mountainous Ground
The produced electric and magnetic fields due to lightning strikes to mountainous ground are determined in this paper. For the sake of simplicity a cone-shaped ground with finite conductivity is assumed to represent a natural nonflat ground. By this assumption, we deal with an axillary symmetrical structure so we use the cylindrical 2D-FDTD to save the simulation memory and time, dramatically. ...

In the past, grounding systems usually were modeled by an individual Resistor. This estimation is useful only at low frequencies, while in high frequencies, the inductance of the grounding system plays the main role to identify the phase and amplitude of that. In recent years, as wind farms grow rapidly throughout the world, the grounding system and ground impedance of wind turbine towers under...

Wind generators are exposed to numerous destructive forces such as lightning and are therefore vulnerable to these phenomena. To evaluate the transient behavior of a wind power plant during direct and indirect strikes, modeling of all relevant components is required. Among the protective and control components of wind turbines, the grounding system is the most important element for protection a...

In this paper, Intelligent water drop algorithm (IWD) is used to analyze single overhead line connected to grid-grounded arrester. In this approach, at first Norton’s equivalent circuit of the overhead line over lossy soil is computed by method of moments (MoM) and then for the problem under consideration, a nonlinear equivalent circuit in the frequency domain is proposed. Finally applying inte...
