WIND-DRIVEN GENERATOR AND YAW ROTATION CONTROL METHOD FOR WIND-DRIVEN GENERATOR

摘要

A wind turbine generator, which is a wind turbine generator that turns a nacelle in the yaw direction by using the force that acts on turbine blades, includes a yaw brake device that stops the turning of the nacelle in the yaw direction and a control device that controls the yaw brake device so that the turning speed of the nacelle falls within a predetermined range. Therefore, the wind turbine generator can make the turning speed of the nacelle constant.
