摘要： 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.

摘要： A lock for preventing rotation of a rotor of a wind turbine has a rotatable lock pin, a pin support supportable in a nacelle of the wind turbine and a mechanism for rotating the lock pin. The pin support has a hub-facing face proximate a rotor hub. The rotatable lock pin is rotatably mounted on the pin support. The lock pin has a cammed portion extending away from the hub-facing face toward the hub. The lock pin inserted into a complementary rotor lock aperture on the rotor hub when the pin support is supported in the nacelle. Rotation of the lock pin causes engagement of an exterior surface of the cammed portion with an interior surface of the rotor lock aperture to immobilize the lock pin against the interior surface to prevent relative motion between the lock pin and the aperture to prevent rotation of the rotor.

摘要： The invention provides a method for determining a wind turbine layout in a wind power plant comprising a plurality of wind turbines. The method comprises the steps of generating a plurality of random layout candidates fulfilling a set of basic requirements, and then performing a pre screening process on each of the plurality of random layout candidates. Based on the pre-screening process, a subset of layout candidates is selected and detailed optimization is performed on the layout candidates of the selected subset of layout candidates. Based on the detailed optimization, an optimized layout for the wind power plant is selected among the optimized layout candidates of the subset of layout candidates.

摘要： An enclosure having an outer surface with a vortex-induced vibration suppression function is provided. The outer surface of the enclosure is provided with a plurality of annular recesses surrounding the enclosure, such that alternately concave and convex annular recesses and annular bosses configured for disrupting a boundary layer of a laminar flow are formed on the outer surface of the enclosure. An outer surface of the annular boss is provided with a plurality of air guiding grooves, and the plurality of air guiding grooves are distributed in a circumferential direction of the annular boss. The air guiding grooves are inclined upward or downward, such that part of an upwind incoming flow flowing to the annular boss can be guided into the annular recesses adjacent to the annular boss via the air guiding grooves. With the convex-concave outer surface, the cause of formation of the vortex-induced vibration can be prevented.

摘要： A heating/heat-retaining device, particularly to a heating/heat-retaining device used in the forging process, and more particularly to an opening-and-closing type heater and a wind generator shaft forging process using the same. The opening-and-closing type heater comprises a base, a tube body mounted on the base and a tube body opening-and-closing mechanism; the tube body comprises a fixed tube body and a movable tube body, the fixed tube body and the movable tube body are arc-shaped shells, and form a hollow shape when the openings thereof match with each other; the tube body opening-and-closing mechanism is connected to the movable tube body for realizing the opening-and-closing of the movable tube body and the fixed tube body. The invention solves heat retaining and heating problems during the forging process of the main shaft forgings and avoids internal defects due to rapid temperature drop of the main shaft forgings.

摘要： A vibration absorber which, in addition to a main mass which is fixed thereto and moved along a curved trajectory by a driving mechanism, comprises a substantially smaller variably adjustable rotating flywheel mass which is moved together with the main mass along the trajectory thereof, enabling the adjustment of the frequency of the absorber. The rotating flywheel mass is driven by a novel belt device independently of the driving mechanism. A rotating vibration absorber which, along with the main mass and the rotating flywheel mass, comprises its own damping unit, such as an eddy-current damping unit.
