Document Type and Number:
Japanese Patent JP6374234
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a state monitoring system capable of promptly and reliably detecting abnormality in devices constituting a wind generator and to provide a wind generator system mounted with the state monitoring system.SOLUTION: A state monitoring system of a wind generator device 10 comprises: sensors which respectively detect states of devices; a monitor device 80 which generates diagnostic parameters on the basis of detection results of respective sensors; a data server 330 which diagnoses abnormality in the devices on the basis of the diagnostic parameters; and a rotation angle sensor which detects a rotation speed of a nacelle. The data server 330 corrects the diagnostic parameters on the basis of the detection result of the rotation angle sensor and diagnoses whether or not the devices have abnormality by comparing the corrected diagnostic parameters with predetermined thresholds.
