Prediction of Interferences Caused by Wind Farms over the TV Broadcast Service

Abstract

One of the environmental effects of wind farms is that wind turbines act as scattering devices of the electromagnetic RF waves and thus, may cause interferences to different telecommunication services around them. A software application that has been developed to predict the interference caused by wind farms to TV broadcast service is presented in this paper. The implemented RCS models of a wind turbine, along with different measurements carried out to adjust and validate the functionality of the software is shown. Finally, a wideband terrain-sensitive channel response model has been developed from narrow-band model. The complex wideband channel transfer function is transformed here to time domain through the use of a fast Fourier transform (FFT), so that calculating the power delay profile (PDP).
