Abstract
Systems, methods, and computer program products for monitoring a wind turbine (). The system receives a signal () indicative of a pitch force being applied to a blade () of a wind turbine (). The signal () is sampled to generate a discrete time-domain signal () including a plurality of pitch force samples. Samples are selected for analysis using a sampling window () that excludes samples obtained under operating conditions determined to be detrimental to obtaining good data. The selected samples are processed to generate a spectral density () of the signal (), and the frequency content of the spectral density () analysed to determine the condition of one or more components of the wind turbine (). If the analysis indicates that a component of the wind turbine () needs attention, the system generates an alarm.
