See the direct and indirect effects of a lightning strike on your wind turbine using our numerical model

We have developed a range of design tools that allow us to perform numerical modelling of both direct and derived effects of a lightning strike on your wind turbine. This provides you with an effective supplement to physical tests and can help you save valuable time – especially if you introduce the modelling early in the development process.

Numerical modelling of phenomena linked to lightning

Using our specially-developed numerical modelling software, we can simulate every electrical or electro-thermal phenomenon related to lightning.

We perform modelling to different degrees of detail, which means you have access to key forecasts on two levels:

 

  1. How materials behave at a component level
  2. How components function at system level


Use our numerical modelling expertise for a variety of purposes, including:

  • Designing a robust Lightning Protection System for turbine blades
  • Evaluating the current dispersion and respect distances in your Lightning Protection System
  • Evaluating the current and voltage dispersion in power and control systems due to the direct and derived effects of lightning
  • Designing earthing systems in difficult soil conditions or near other infrastructure systems

The simulated geometries cover a broad spectrum: everything from the thickness of a coat of varnish on copper coils in electric machines (in µm), to terrain topographies in wind farms and on sea beds (in km).

We have thoroughly tested and verified our model, where we use 3D/2D FEM analyses, FDTD and EMTP models in the frequency and time domain.

Insulation Coordination

You can also use our modelling tools to perform insulation coordination (IC).

In such cases, we model your installation and analyze lightning flows and transient overvoltage to ensure that the components’ impulse withstand voltages are not exceeded.
