Wind turbine horizontal axis and method for controlling the wind turbine horizontal axis.

摘要

Wind turbine horizontal axis type windward, comprising: - a rotor (4) for rotation about a rotor axis X extending in a horizontal direction, the rotor (4) being rotated in a horizontal plane according to direction of the wind; - a nacelle (3) having a symmetrically with respect to an imaginary plane (V) containing the rotor axis X and extending in the vertical direction; - two anemometers (L, R) mounted on the nacelle (3), and - a controller for controlling an orientation angle (φ) of a rotor (4) based on wind speeds measured by the two anemometers (L, R). - wherein the two anemometers (L, R) are arranged in positions on both sides of the nacelle (3), wherein the positions are opposite to each other across the imaginary plane (V).
