WIND TURBINE WITH FLOATING FOUNDATION AND POSITION REGULATING CONTROL SYSTEM AND METHOD THEREOF

摘要

The present invention relates to a wind turbine structure comprising a wind turbine tower with a nacelle arranged on the top to which a rotor hub with one or more rotata- ble mounted wind turbine blades are mounted which form a rotor plane. A floating foundation is mounted to the bottom of the wind turbine tower and the pitch and/or yaw system are used to regulate the position of the wind turbine structure. A control unit detects the relative movement of the wind turbine structure in two axial directions and activates the pitch or yaw system to move the wind turbine structure into an equi- librium position. This reduces the directional movement of the wind turbine structure so that it remains in a stable equilibrium position. This also reduces the oscillating movement and tension forces in the anchor chains.
