    Abstract: Structures and methods for joining misaligned or dissimilar width spar caps are disclosed as having a connecting structure in a rotor blade assembly for a wind turbine, wherein a first blade segment defines a first joint end, the first blade segment having at least one spar cap. A second blade segment defines a forward end coupled to the first blade segment, the second blade segment having at least one spar cap offset from the spar cap of the adjoining first blade segment. At least one connecting structure is coupled between the adjoining spar caps of the first blade segment and the second blade segment, the connecting structure having a plurality of sequentially stacked plies configured for parallel fiber alignment with the adjoining spar caps and cross-sectional area continuity with the adjoining spar caps.

    Abstract: The present disclosure is directed to a system and method for controlling a wind turbine during adverse wind conditions. In one embodiment, the method includes monitoring one or more wind conditions near the wind turbine. Another step includes detecting one or more adverse wind conditions near the wind turbine. In response to detecting one or more adverse wind conditions, the method also includes reducing a power output of the wind turbine by a predetermined percentage. Further, the predetermined percentage is a function of a number and a type of the detected adverse wind conditions occurring during a predetermined time period.

    Abstract: A blade insert for coupling a first blade segment to a second blade segment is disclosed. The blade insert may generally include an aerodynamic body extending between a forward end configured to be coupled to the first blade segment and an aft end configured to be coupled to the second blade segment. The aerodynamic body may include a top side extending between a forward edge and an aft edge. The top side may define a top scarfed section at its forward edge. The aerodynamic body may further include a bottom side extending between a forward edge and an aft edge. The bottom side may define a bottom scarfed section at its forward edge. Additionally, at least a portion of the forward edge of the top side may be configured to be offset relative to the forward edge of the bottom side.

    Abstract: A counterweight system for mounting a rotor blade on a balanced rotatable hub of a wind turbine is disclosed. The rotatable hub can have at least one blade root region configured to receive a blade root of the rotor blade, and also have a pitch system configured to rotate the rotor blade around a pitch axis. The counterweight system can have at least one support structure having a proximal end spaced apart from a distal end with the proximal end mountable to at least one blade root region of the rotatable hub. The at least one counterweight mass can be at least partially filled with fluid and coupled to the distal end of the at least one support structure. The at least one support structure can be arranged substantially parallel to the pitch axis such that the pitch system rotates the counterweight mass about the pitch axis.
