Flow controlled wind turbine for wind power plant has vanes, each with aerodynamic symmetrical profile in cross-section over their entire lengths, wind vane arranged to determine wind direction

摘要

The device has one or more vanes (3) rotating about a vertical central axis (4) via a main bearing (5) and parallel to and joined to the main vertical axis by horizontal bearers (6) in which they are freely rotatable in bearings (7) and able to be aligned in the wind direction. The vanes each have an aerodynamic, symmetrical profile in cross-section over their entire lengths. A wind vane (9) is arranged to determine the wind direction.
