The interference caused by wind turbines creates blind spots in the radar coverage when a wind turbine is installed in the line of sight of the radar installation. In the interest of national security, permission to install wind turbines in the line of sight of existing radar installations may ...
The present invention relates to a control system for thrust-limiting of wind turbines, which wind turbine comprises at least one tower, which tower carries at least one nacelle which nacelle comprises a rotating shaft, which shaft is rotated by one or more blades, which blades at pitch regula...
