風力発電装置及び風力発電システム
Document Type and Number:
Japanese Patent JP7146580
Kind Code:
B2
Abstract:
To provide a wind power generation device and a wind power generation system, capable of early determining abnormality of a yaw actuator.SOLUTION: A wind power generation device comprises: a nacelle 22 that supports a rotor rotating with wind; a tower 21 that rotatably supports the nacelle 22; a plurality of yaw actuators 10 that rotates the nacelle 22 with respect to the tower 21; and an abnormality detection device that detects an abnormality in the yaw actuator 10. The abnormality detection device compares the total value of the outputs of the yaw actuators 10 with a predetermined first threshold value, and when the total value of the outputs exceeds the predetermined first threshold value, determines that the yaw actuators 10 are in an abnormal state.SELECTED DRAWING: Figure 3
