Abstract: The invention relates to a method for performing up-tower maintenance on a gearbox bearing of a wind turbine. In particular, a method for performing up-tower maintenance on a gearbox of a wind turbine is disclosed. The gearbox has at least one bearing with an outer race and an inner race that rotates with respect to the outer race. The method includes forming a through-hole in a front cover of the gearbox, the front cover being stationary with respect to an axis of rotation of the bearing. The method also includes forming a recess in the outer race of the bearing. Further, the method includes inserting a connecting member through the through-hole and the recess so as to prevent movement of the outer race of the bearing with respect to a torque arm of the gearbox.

Abstract: A method for replacing an existing generator frame that supports a generator of a wind turbine includes removing the generator from atop the existing generator frame. The method also includes dismounting a control cabinet of the wind turbine from the existing generator frame. More specifically, the control cabinet is electrically connected to one or more wind turbine components via a plurality of cables. The method further includes relocating and securing the control cabinet to an uptower location within a nacelle of the wind turbine with the plurality of cables remaining electrically connected. As such, the method includes removing the existing generator frame from within the nacelle. Moreover, the method includes installing a new generator frame in place of the removed existing generator frame. Thus, the method also includes remounting the control cabinet to the new generator frame.

Abstract: A system includes a resonant sensor in contact with oil within a gearbox of a rotor system, such as a wind turbine, and one or more processors. The sensor includes electrodes and a sensing circuit that generates electrical stimuli having frequencies applied to the oil at different times during a life of the gearbox. The processors receive electrical signals from the resonant sensor representative of impedance responses of the oil to the electrical stimuli. The processors analyze the impedance responses and determine a concentration of a polar analyte in the oil at different times. The processors calculate a degradation value for the gearbox based on the concentration of the polar analyte. Responsive to the degradation value exceeding a designated threshold, the processors at least one of schedule maintenance for the rotor system, provide an alert to schedule maintenance, or prohibit operation of the rotor system until maintenance is performed.

Abstract: A method for determining an amount of water contamination in oil of a gearbox of a wind turbine includes receiving, via a controller, one or more operational parameters of the wind turbine. The method also includes receiving, via the controller, one or more weather conditions at the wind turbine. Further, the method includes calculating, via the controller, the amount of water contamination in the oil of the gearbox as a function of the one or more operational parameters of the wind turbine and the one or more weather conditions at the wind turbine. In addition, the method includes implementing, via the controller, a corrective action based on the calculated amount of water contamination in the oil of the gearbox.
