Title:
WIND POWER GENERATION DEVICE AND CONTROL METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2019/163326
Kind Code:
A1
Abstract:
Provided are: a wind power generation device which can suppress mechanical wear while increasing power generation amount by reducing a yaw deviation angle; and a control method for same. This wind power generation device (1) is provided with: a rotor (4) that rotates upon receiving wind; a nacelle (5) that rotatably supports the rotor (4); a tower (7) that supports the nacelle in a yaw-rotatable manner; an adjustment device (8) that adjusts the yaw of the nacelle (5) on the basis of a yaw control command; and a control device (9) that determines the yaw control command to be transmitted to the adjustment device (8). The control device (9) is provided with: a yaw deviation angle calculation unit (301) that calculates the yaw deviation angle from the wind direction measured by a wind direction and velocity measuring unit and the direction of the rotor (4); and a control command creation unit (305) that determines the yaw control command on the basis of the yaw deviation angle, wherein the control command creation unit (305) raises the driving speed of yaw rotation when the level of disturbance in the wind conditions is high.
