Abstract

Coexistence of wind farms and terrestrial radio links require the investigation of suitable exclusion zones. A proper analysis of this interference including the effect of diffraction is very difficult by numerical field simulation as the problem is electrically extremely large. We propose and analyze a simple diffraction model for a wind turbine (WT) based on a one-dimensional Fresnel diffraction approach applied to tower and rotor. For the first time the dynamic behavior of the diffraction caused by the rotor blades has been investigated.
