Abstract
A yaw control system for a wind turbine generator includes a yaw direction sensor for detecting a yaw direction value of the nacelle at a current time, a yaw rotation amount calculation part for calculating an amount of yaw rotation of the nacelle in a predetermined period of time based on a yaw rotation speed and a yaw rotation time of the nacelle, a yaw direction estimation part for calculating an estimate value of a yaw direction of the nacelle at an end point of the predetermined period by an estimate value calculation logic based on the amount of yaw rotation in the predetermined period calculated by the yaw rotation amount calculation part and the yaw direction value at a starting point of the predetermined period, and a yaw drive control part for controlling the yaw drive mechanism.
