Abstract: A system (1) for recirculation of air in a component of a wind turbine, such as a converter cabinet (2), a nacelle, a generator, etc. The system (1) comprises a housing (5) enclosing the system (1), a fan (4) arranged inside the housing (5) for recirculating the air, an opening (6) arranged in a wall part of the housing (5) and having a filter (7) arranged across it, and means for drawing air from outside the housing (5) to inside the housing (5) via the opening (6) and the filter (7). The air may be drawn through the opening (6) due to a low pressure created when the fan (4) draws air through a heat exchanger (3) arranged in the system (1). Drawing air through the opening (6) creates an overpressure inside the housing (5), and thereby air from outside is prevented from entering the system (1) via possible holes or crevices in the housing (5). Since air entering the system (1) flows via the filter (7), dirt and impurities are therefore prevented from entering the system. Thereby the wind turbine is protected. The system (1) may be a cooling system, e.g. for electronics of the wind turbine.

Abstract: A node structure for connecting a member of a lattice frame to one or more other members of the frame comprises a hollow brace having opposed walls that converge outwardly at an acute angle in cross-section toward a central plane to connect at an outer edge. At least one root portion has a central longitudinal axis extending outwardly in the central plane of the brace for alignment with a member of the frame. The root portion has an inner end cut away at opposite sides around the central plane to leave a joining surface that intersects the converging walls of the brace while embracing an outer region of the brace extending inwardly from the outer edge.

Abstract: A system (24) and method are described herein for manufacturing a wind turbine blade (22) proximate to the final installation site of a wind turbine (10). The system (24) includes a creel (72) of feeders (74) configured to apply strengthening elements (62) onto a plurality of shell core sections (26) coupled together and fed through the creel (72). The shell core sections (26) include an external surface (56) with a plurality of external grooves (58) recessed into the external surface (56) such that the strengthening elements (62) are laid into the external grooves (58). The system (24) also includes a deposition station (78) configured to apply an outer surface material layer (82) in fluid form to cover the external surface (56) and the plurality of strengthening elements (62). A curing station (86) heats and consolidates the shell core sections (26), the strengthening elements (62), and the outer surface material layer (82) together into a final consolidated part, with the outer surface material layer (82) defining an external profile of the blade (22) following curing.

Abstract: A system for a wind park including: a control system in communication with a plurality of unmanned air vehicles, wherein the control system is configured to deploy one or more unmanned air vehicles during a triggering condition; and wherein the deployed unmanned air vehicles are guided towards an assigned wind turbine and to interact with a blade of that wind turbine in order to control oscillation of the blade. The invention also embraces a method for reducing blade oscillations of a wind turbine, comprising: monitoring for a triggering condition associated with the wind turbine; on detecting the triggering condition, deploying unmanned air vehicles towards a wind turbine and interacting with a blade of the wind turbine using the unmanned air to control oscillation of the blade. The invention therefore provides an efficient approach to controlling blade oscillations with minimal human operator involvement. Drones may be deployed automatically once suitable conditions are detected and may automatically engage with the blades, either by contacting those blades physically, or by interacting with the blades in close proximity, in order to disrupt airflow around the blades thereby reducing oscillations.
