Abstract: A main nacelle unit (22) for forming a nacelle (14) of a wind turbine (10) includes a main housing (28) having an outer wall (30a. 30b) and containing a base frame (52) configured to be attached to a tower (12) of the wind turbine (10). The main nacelle unit (22) also includes at least one support frame (56) configured to support a wind turbine component (54) external to the main housing (28). A portion of the support frame (56) is attached to the base frame (52) and movable between a stored position and a deployed position. In the stored position, the portion of the support frame (56) is configured to be positioned within the confines of the main housing (28), and in the deployed position, the portion of the support frame (56) is configured to extend through the main housing outer wall (30a. 30b) to support the wind turbine component (54) external to the main housing (28). A method of assembling a wind turbine using the support assembly is also disclosed.

Abstract: A method for controlling a wind turbine to decrease blade deflection during tower passage is disclosed. A blade flap moment of the wind turbine blades is measured. A blade flap moment of the wind turbine blades and a rotor tilt moment in a situation where the pitch offset has not been added are estimated, based on the measured blade flap moment. In the case that the estimated blade flap moment exceeds a first activation threshold value and the estimated rotor tilt moment exceeds a second activation threshold value, individual pitch angle adjustment of the wind turbine blades is initiated by adding a pitch offset, at azimuth angles within an azimuth adjustment region corresponding to tower passage of the wind turbine blades.

Abstract: Aspects of the present invention relate to a computer-implemented method for predicting energy production losses associated with high wind hysteresis control of a wind turbine generator. The method comprises: determining a distribution of wind speeds; determining a high wind hysteresis band that comprises wind speed values between an upper threshold and a lower threshold; and predicting energy production loss due to the high wind hysteresis control. The prediction includes: determining a high wind factor corresponding to a probability that the wind speeds in the hysteresis band occur when the generator is shut off by the high wind hysteresis control, determining, based on the distribution and power data, an energy value associated with the wind speeds falling within the hysteresis band over a predetermined time period; and determining the energy production loss by applying the high wind factor to the determined energy value.

Abstract: A method of correcting a pitch angle deviation of a blade of a wind turbine is provided. First blade load measurements measured when the wind turbine was operating in a first operational mode are provided, and used to determine calibration parameters. Second blade load measurements measured when the wind turbine was operating in a second operational mode are provided, and the calibration parameters applied to determine calibrated blade load measurements. A pitch angle deviation of at least one blade of the turbine is estimated based on an identified difference between the calibrated blade load measurements, and a pitch angle is adjusted to correct for the pitch angle deviation.

Abstract: A transport frame (100, 102) for a nacelle (14) includes a pair of lower nacelle mounts (128, 130) and a pair of upper nacelle mounts (204, 206). Each of the lower nacelle mounts (128, 130) includes a plurality attachment points for attaching to the nacelle (14) at a plurality of different widths. Each of the upper nacelle mounts (204, 206) includes a plurality of attachment points for attaching to the nacelle (14) at a plurality of different widths. The pair of lower nacelle mounts (128, 130) and the pair of upper nacelle mounts (204, 206) are adjustably positioned to allow the transport frame (100, 102) to attach to the nacelle (14) at a plurality of different heights. The ability of the transport frame (100, 102) to attach to the nacelle (14) at a plurality of different widths and heights allows the transport frame (100, 102) to be used on nacelles (14) having different sizes. Methods of using the transport frames (100, 102) are also disclosed.

Abstract: Embodiments herein describe a discharge filter, located in a root of a wind turbine blade, which includes one or more cables wound into large scale inductors using an internal or external surface of the root as a mandrel. These cables provide power inputs to an electrical panel for one or more a powered systems that are located in a body of the wind turbine blade. The electrical panel is connected to a lightning protection system that selectively provides a path to ground, and the inductors form a high-impedance barrier that shunts power away from the cables and onto the lightning protection system in the event of a lightning strike or other electrical discharge traveling from the powered systems to the electrical panel.

Abstract: The invention relates to adjusting pitch of rotor blades of a wind turbine. An acceleration signal is received from a wind turbine acceleration sensor and is indicative of side-to-side motion of the wind turbine tower. A first component in a fixed coordinate frame of the wind turbine is determined based on the received acceleration signal. The first component is indicative of a whirling mode of the wind turbine caused by edgewise vibrations of the rotor blades. A second component is generated based on the first component and is orthogonal to the first component. A control action is applied to obtain first and second control components for mitigating the whirling mode. An inverse m-blade coordinate transformation is applied to the first and second control components to obtain pitch reference offset values in a rotor coordinate frame of the wind turbine, which are used to adjust pitch of the rotor blades.

Abstract: According to the present invention there is provided a wind turbine blade extending in a spanwise direction between a root and a tip, and in a chordwise direction between a leading edge and a trailing edge. The wind turbine blade has a spar cap comprising a plurality of strips of fibrous composite material. Each strip extends in the spanwise direction between a first end and a second end to define a length of the strip, and each strip has a width and a thickness, the width being less than the length, and the thickness being less than the width. Each strip has upper and lower major surfaces defined by the length and width dimensions. Each strip has side surfaces defined by the length and thickness dimensions. The plurality of strips includes a first strip and a second strip. The first strip has a tapered end portion in which the thickness of the first strip decreases towards the first end of the first strip. The tapered end portion defines a tapered end face inclined with respect to the upper and lower major surfaces of the first strip. The first and second strips are bonded together such that the first end of the first strip meets the upper or lower major surface of the second strip to define an interface between the first and second strips. The spar cap further comprises a patch arranged across the interface. The patch comprises a stack of fibrous plies.
