Abstract: A system and method are provided for reducing vibrations and loads in one or more rotor blades on a rotor hub of a wind turbine when the rotor hub is in a locked or idling condition. An electronically tunable mass damper is attached to a fixed location on one or more of the rotor blades. The mass damper is maintained on the rotor blades during the locked or idling condition of the rotor hub. The method includes sensing movement of a mass component of the mass damper from vibrations or oscillations induced in the rotor blade. The mass damper is automatically tuned based on the sensed movements of the mass component by automatically varying an electrical characteristic of the mass damper.

Abstract: A method for identifying a blade run-away condition in the event of a pitch system failure of a rotor blade of a wind turbine includes determining, via one or more sensors, an actual rotor loading of the wind turbine. The method also includes determining, via a turbine controller, an estimated rotor loading of the wind turbine based on at least one of one or more operating conditions of the wind turbine or one or more wind conditions of the wind turbine. Further, the method includes determining a difference between the actual rotor loading and the estimated rotor loading. The method also includes determining whether the blade run-away condition is present based on the difference. The method may also include implementing a corrective action that mitigates loads caused by the blade run-away condition.

Abstract: A method for controlling loads of a wind turbine includes receiving sensor signals from one or more sensors being indicative of a movement of a nacelle of the wind turbine from a reference point. More particularly, the movement corresponds, at least, to a tilt and/or a displacement of the wind turbine tower and/or nacelle. The method also includes generating a deflection profile of the tower along its overall length from a bottom end to a top end thereof based on the sensor signals. Further, the method includes determining at least one of a thrust or a tower load of the wind turbine from the deflection profile. In addition, the method includes implementing a control action for the wind turbine based on the thrust and/or the tower load.

Abstract: A method for reducing loads of a wind turbine includes determining an operational state of the wind turbine. The method also includes commanding a predetermined pitch event. Further, the method includes monitoring at least one operating condition of a pitch drive mechanism of a rotor blade of the wind turbine during the predetermined pitch event. If the operational state corresponds to a predetermined operational state and the operating condition(s) follows a pitch fault pattern during the predetermined pitch event, the method also include yawing a nacelle of the wind turbine away from an incoming wind direction.

Abstract: A bonded window cover for an access window of a rotor blade assembly having a unique joint assembly is provided. For example, for rotor blade assembly having blade inserts that form access windows with the rotor blade segments, the laminated in window covers are replaced with bonded windows. More specifically, the bonded-in window covers are bonded in with a window frame lap joint, which allows the transition from two sets of inner skin layers (bonded onto one another) to one set of inner skin layers. Without this transition, the leading edge would have an undesirable bump or protrusion as well as waves in the skin layers.
