<p>A method for controlling a two-bladed wind turbine in extreme wind conditions is described, wherein when extreme conditions are detected or forecast for the wind turbine, the wind turbine blades are positioned in a horizontal arrangement, and actively yawed such that a tip of one of the wind turbine blades points into the wind direction. The blades are yawed such as to actively follow the changing wind direction, resulting in a reduced surface area of the blades exposed to the extreme wind forces, due to the spear-like arrangement of the turbine blades. This reduced surface area provides for a reduction in the extreme loads which may be experienced by the wind turbine in such extreme wind conditions.</p> |
