Wind Turbine

Wind Turbine

As is an inherent in the physics of a downwind configuration, the stronger the wind, the larger the clearance between the blades and the tower by blade flexion. This results in a lower probability of a tower hit. In case of stand still mode, downwind turbine switches to a free yaw operation mode and wards off the cross wind by the weather vane principle without yaw control even in case of black out conditions. This, in principle, reduces overturning moment to the foundation or floaters and maintains high degree of safety. That is important especially for offshore projects. Also, the wind sensors installed at the front of the blades give a more precise wind direction and speed in the upper stream. Yaw and blade pitch shall also be modulated to the right angle for more production.
