Mitigation of the impact of wind turbine (WT) forward scattering on radars, navigation systems and terrestrial radio links requires accurate modelling and rapid calculation of diffraction of RF and microwave signals at the tower and rotor of WTs. A proper analysis by 3D numerical field simulation is very time consuming as the problem is electrically extremely large. We are using 2D Fresnel-Kirchhoff...
Radar doppler deviation caused by the time variant diffraction of the two-way signal at the rotating blades of a wind turbine (WT) is analyzed based on a one-dimensional Fresnel diffraction approach. In order to provide an insight into the degradation of the radar performance, time variant forward scatter path loss, phase shift and corresponding frequency shift are investigated.
Wind power generation is becoming increasingly common in the portfolio mix of many utilities around the world. Wind turbines are presently available up to 5MW. Smaller turbines may be installed for individual customers and connected to the grid at the distribution level, and larger units are typically combined in a wind “farms” connected to bulk power systems at the transmission level. Turbines ranging...
