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.

A horizontal axis wind turbine comprising:
- a rotor for rotating around a rotor axis extending in a horizontal 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 both side portions so that wind speeds measured by the anemometers are different except when a yaw angle of the rotor is 0 degree;
- and
- a controller for controlling the yaw angle of the rotor based on the wind speeds measured by the two anemometer.
