CONDITION MONITORING SYSTEM AND WIND POWER GENERATION SYSTEM USING SAME

Document Type and Number:

WIPO Patent Application WO/2015/198793

Kind Code:

A1

Abstract:

A condition monitoring system for a wind power generation device (10) is provided with sensors that detect conditions of equipment, a monitor device (80) that generates a diagnosis parameter on the basis of detection results of the sensors, a data server (330) that diagnoses an abnormality of the equipment on the basis of a diagnosis parameter, and a rotation angle sensor for detecting a rotation speed of a nacelle. The data server (330) corrects the diagnosis parameter on the basis of the detection result of the rotation angle sensor and compares the corrected diagnosis parameter with a predetermined threshold value, thereby diagnosing whether the equipment is abnormal or not.
