Zusammenfassung:It is described a method of monitoring a blade pitch bearing (17) of a rotor blade (13) of a wind turbine (1), the method comprising: pitching the rotor blade (13); measuring an amount of a vibration (37, 45) of the blade pitch bearing (17) during the pitching; estimating a condition of the blade pitch bearing (17) based on the measured amount of vibration (37, 45).
