Publication number: 20180320662Abstract: A windmill rotation restrictor device restricts the speed of rotation of front blades of a decorative windmill in high winds. The device includes a windmill having a base, a rotor, and a vane. The rotor includes a front blade assembly and a front shaft extending from the front blade assembly. The front shaft is freely rotatable relative to the base. The vane includes a rear blade assembly and a rear shaft extending from the rear blade assembly. The rear shaft is freely rotatable relative to the base. The front blade assembly and the rear blade assembly rotate in opposite directions when blown by wind from a single direction. A linkage couples the front shaft to the rear shaft such that rotation of the rear blade assembly counteracts and slows rotation of the front blade assembly.Type: ApplicationFiled: May 8, 2017Publication date: November 8, 2018Inventor: Mark Buysse

Publication number: 20180320663Abstract: Embodiments of the present invention relate to control of a wind turbine during a recovery period after a grid fault. It is disclosed to operate a wind turbine during the recovery period to determine the actual pitch angle of the rotor blades and the actual wind speed, and based on that determining a desired pitch angle of the rotor blades, as well as a pitch ramp rate so that the actual pitch angle can be brought to match the desired pitch angle before the end of the recovery period. In embodiments, the steps performed in the recovery mode are repeated at intervals during the recovery period.Type: ApplicationFiled: November 17, 2016Publication date: November 8, 2018Inventors: Martin Ansbjerg KJÆR, Kasper Zinck OSTERGAARD, Jan GRAUGAARD-JENSEN

Publication number: 20180320665Abstract: An enclosure for a nacelle of a wind turbine is connected to a substructure in a manner that allows the enclosure to move relative to the substructure. An imaginary straight line extends over the panel and is aligned with an edge of the panel. The imaginary straight line defines a first sub-portion of the panel, said first sub-portion comprising the edge. The first sub-portion butts against the substructure. The first sub-portion is retained against the substructure by a tension element acting in a direction of tension. The first sub-portion can be displaced relative to the substructure in a direction which intersects the direction of tension. The invention facilitates the operation of assembling the enclosure.Type: ApplicationFiled: May 3, 2018Publication date: November 8, 2018Inventor: Nils Lieckfeldt

Publication number: 20180320667Abstract: Assessing performance impact of a power upgrade of one or more wind turbines of a wind farm that includes a group of target wind turbines and a group of reference wind turbines. For each of the target wind turbines, a transfer function is generated, establishing a relationship between the locally measured wind speed at the target wind turbine and locally measured wind speeds at each of the reference wind turbines. A power upgrade is performed on each of the target wind turbines, and subsequently power performance data is obtained for the reference wind turbines and the target wind turbines, within one or more wind speed intervals. For the target wind turbines, the wind speed intervals are based on estimated wind speeds, based on locally measured wind speeds at the reference wind turbines and the transfer functions.Type: ApplicationFiled: November 10, 2016Publication date: November 8, 2018Inventors: Dan BELTOFT, Sven Jesper KNUDSEN, Carsten Krogh NIELSEN

Publication number: 20180320669Abstract: Disclosed are devices, systems, apparatuses, methods, products, and other implementations of vapor pressure solids. In some embodiments, a vapor pressure solid may include a one- or multi-component matrix material. In some embodiments, the multi-components matrix material is a two-part PDMS comprising a first and second matrix material. The first matrix material is capable of being mixed with one or more vaporizable fluids that causes the first matrix material to swell. The second matrix material is capable of being mixed with the swelled first matrix material to produce an actuating material. When the actuating material is heated, the one or more vaporizable fluids expand, resulting in vapors. The increased pressure applied by the vapors causes the actuating material to expand.Type: ApplicationFiled: June 1, 2018Publication date: November 8, 2018Inventors: Kenneth William Stack, Aslan Miriyev, Hod Lipson
