HORIZONTAL AXIS WIND TURBINE AND METHOD FOR CONTROLLING HORIZONTAL AXIS WIND TURBINE

摘要

A horizontal axis wind turbine comprises the following components: a yaw sensor (10); a rotor (4) rotating around a rotor axis (X) extending in a substantially horizontal direction, the rotor axis (X) rotating in a substantially horizontal plane depending on the wind direction; a plate-like member (5) disposed on a rotational central portion of the rotor (4) and extending in a parallel direction to the rotor axis (X) and in a vertical direction; two anemometers (A, B) disposed at positions which are across the plate-like member (5); and a controller (100) for yaw control based on a difference or a ratio between wind speeds measured by the two anemometers (A, B).
