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. A mass damper is attached at a fixed location on one or more of the rotor blades and is maintained on the rotor blades during the locked or idling condition of the rotor hub. The mass damper includes a movable mass component that is responsive to changes in the vibrations or oscillations induced in the rotor blades during the locked or idling condition of the rotor hub.

Abstract: A method for reducing loads of a wind turbine includes determining a wind speed at the wind turbine. Further, the method includes determining an operational state of the wind turbine. The method also includes determining whether a rotor of the wind turbine is imbalanced beyond a predetermined threshold when the operational state corresponds to a predetermined operational state as a rotor imbalance beyond the predetermined threshold is indicative of a pitch fault in one or more of the rotor blades. In addition, the method includes yawing a nacelle of the wind turbine to a predetermined angular position when the wind speed exceeds a predetermined speed threshold and the rotor is imbalanced beyond the predetermined threshold.

Abstract: A method for estimating consumed battery life of at least one battery of a pitch drive mechanism of a rotor blade of a wind turbine includes monitoring, via at least one sensor, an actual temperature of the battery over a predetermined time period. The method also includes storing, via a turbine controller, the monitored actual temperatures of the battery during the predetermined time period. Further, the method includes determining, via the turbine controller, the consumed battery life as a function of the monitored actual temperatures.

Abstract: A method for reducing loads of a wind turbine includes determining an angular pitch speed parameter of the rotor blade of the wind turbine. The method also includes determining an operational state of the wind turbine. Further, the method includes comparing the angular pitch speed parameter to a predetermined parameter threshold during turbine shutdown and/or a commanded pitch event. If the operational state corresponds to a predetermined operational state, the method includes yawing a nacelle of the wind turbine away from an incoming wind direction when the angular pitch speed parameter is below the predetermined parameter threshold during the turbine shutdown and/or the commanded pitch event.

Abstract: A system and method are provided for reducing vibrations and loads in one or more rotor blades of a wind turbine when the rotor hub is locked against rotation, The method detects that the rotor blades are vibrating above a threshold limit, and determines one or more wind parameters for wind impacting the rotor blades. An initial orientation of the blades is also determined. Based on the wind parameters and initial blade orientation, a first angle of attack for the rotor blades is determined that will reduce the vibrations in the rotor blades. The method then determines if expected loads induced at one or more wind turbine components will exceed a threshold limit at the first angle of attack for the rotor blades. The first angle of attack is modified when the expected loads exceed the threshold limit to reduce the expected loads to below the threshold limit. A controller pitches the rotor blades to achieve the first angle of attack.

Abstract: Apparatus, systems, and methods are provided for determining remaining lifetime of a battery, such as a battery used to power a pitch drive system in a wind turbine. In one example implementation, a method can include controlling a discharge of the battery through a load. The method can include obtaining data indicative of a discharge voltage and a discharge current of the battery during discharge through the load. The method can include obtaining data indicative of a temperature associated with the battery during discharge through the load. The method can include determining data indicative of remaining lifetime of the battery as a function of the discharge voltage, discharge current, and the temperature. The method can include performing at least one control action based at least in part on the data indicative of remaining lifetime of the battery.

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 wind turbine tower includes a door access opening in a down tower area of the tower. A hinged door panel covers the door access opening, with a ventilation opening defined through the door panel. A multi-sided intake structure, such as a box-like structure, is connected to an exterior of the door panel over the first ventilation opening. The intake structure extends transversely from the door panel and includes a top side, a bottom side, and at least two vertical sides extending between the top side and the bottom side. The vertical sides are open to air flow therethrough. The top and bottom sides may also be open to air flow therethrough. Air from multiple directions is drawn into an interior of the wind turbine tower through the intake structure and ventilation opening. A filtering system with first and second stage filters may be incorporated with any of the intake structures.

Abstract: A method for installing an add-on device onto a blade of a wind turbine includes configuring a plurality of tag lines to a wrap, the tag lines having a length to extend to a ground location when the add-on device is positioned on the blade. With the rotor, positioning the blade to a first rotated position. The add-on device is located at a desired span-wise location on the blade such that the wrap forms an open-sleeve configuration draped around the leading edge of the blade and span-wise sides of the wrap extend along pressure and suction sides of the blade adjacent a trailing edge of the blade. With the tag lines, the wrap is tensioned against the blade. Attachment devices configured with the wrap are affixed to the trailing edge of the blade.
