The invention relates to a method (340) for stabilising a drive train (106) of a wind turbine (100), wherein the wind turbine (100) comprises at least one rotor blade (112), a machine carrier (128) and, as main components (118, 120, 122), a bearing (118), a transmission (120) and a generator (122) arranged on the machine carrier (128). The method (340) comprises the following steps: reading (342) an acceleration signal (462) and a reference signal (464); converting (344) the acceleration signal (462) using the reference signal (464), in order to obtain an adapted acceleration signal (468); determining (346) a force (472) acting on the main components (118, 120, 122) using the adapted acceleration signal (468); ascertaining (348) a counterforce (476) compensating for the force (472), using the force (472); and determining (350) a control variable (478) using the counterforce in order to stabilise the drive train (106) of the wind turbine (100), wherein the control variable (478) represents a pitch angle (114) of the at least one rotor blade (112). In addition, the reference signal (464) represents at least one acceleration at the machine carrier (128), and the acceleration signal (462) represents at least one acceleration at at least one main component (118, 120, 122). |
