ABSTRACT:
A horizontal axis wind turbine of an upwind type includes: a rotor for rotating around a rotor axis extending in a horizontal direction, the rotor being turned in a horizontal plane according to a wind direction; a nacelle having a symmetrical shape with respect to an imaginary plane including the rotor axis and extending a vertical direction; two anemometers disposed at positions of both side portions of the nacelle, the positions opposing each other across the imaginary plane; and a controller for controlling a yaw angle of the rotor based on wind speeds measured by the two anemometers.
