Abstract
A condition monitoring system for a wind turbine includes: each sensor to sense a condition of equipment; a monitor device configured to generate a diagnosis parameter based on a detection result of each sensor; a data server configured to diagnose a failure of the equipment based on the diagnosis parameter; and a rotation angle sensor for sensing the nacelle's rotation speed. The data server is configured to correct the diagnosis parameter based on a sensed result of the rotation angle sensor, and diagnose whether the equipment has a failure by comparing the corrected diagnosis parameter with a predetermined threshold value.
