08 Dec 2015TL;DR: In this article, a method of setting a reference DC-link voltage of a wind-turbine converter system is provided, where at least at least one DC voltage demand from a generator-side inverter is derived.
Abstract: A method of setting a reference DC-link voltage of a wind-turbine converter system is provided. At least at least one DC voltage demand from at least one generator-side inverter and at least one DC voltage demand are received from at least one grid-side inverter. A generator-side DC voltage demand value on the basis of the at least one DC voltage demand received from the at least one generator-side inverter. Also a grid-side DC voltage demand value is determined on the basis of the at least one DC voltage demand received from the at least one grid-side inverter. The highest DC voltage demand value out of the generator-side and grid-side DC voltage demand values is chosen. This chosen value corresponds to the set reference DC-link voltage.

24 Feb 2017TL;DR: In this article, a wind turbine system with several wind turbine modules mounted to a support structure is described, and a control system is configured to determine a lift command (21) for a particular wind turbine module (2 ) of the 5 plurality of wind turbines modules.
Abstract: The invention relates to a wind turbine system ( 1 ) with several wind turbine modules ( 2 ) mounted to a support structure ( 3 ). A control system is configured to determine a lift command ( 21 ) for a particular wind turbine module ( 2 ′) of the 5 plurality of wind turbines modules ( 2 ). The control system is applying the lift command ( 21 ) to a corresponding rotor blade pitch adjustment system of the particular wind turbine module ( 2 ′) so as to create a lift force (F_up) in the opposite direction of gravity on the particular wind turbine module mounted on the support structure. Providing an upwards lift force on one, or more, particular 10 wind turbine module(s) may reduce, or eliminate, static and/or dynamical loads from the wind turbine module on the support structure.

20 Dec 2012TL;DR: In this article, a bridging sheet is accommodated in the recessed portions of the mould shell sections of a wind turbine blade, where the bridging covers are filled up with the recised portions.
Abstract: A mould shell for forming a wind turbine blade (20) comprises at least two mould shell sections (401, 402) each having a mould surface with a recessed portion (419, 420) adjoining the connecting edges (407, 408) between the mould shell sections. A bridging sheet (421) is accommodated in the recessed portions (419, 420) of the mould shell sections (401, 402). The bridging sheet (421) fills up the recessed portions.

TL;DR: In this article, the authors investigate the impact of linear MPC on the performance of a wind turbine and propose an approach in which this problem is handled by adjusting relevant model parameters in the linearized model to fit the actual physical wind turbine behavior.

25 Nov 2016TL;DR: In this paper, an anchor cage is placed in an excavation pit, the anchor cage including an upper flange, a lower flange and a plurality of anchor bolts extending there between, and an actuating element is actuated relative to the connecting element.
Abstract: A method of forming a wind turbine foundation includes providing an anchor cage in an excavation pit, the anchor cage including an upper flange, a lower flange, and a plurality of anchor bolts extending therebetween. A first cementitious material is directed into the excavation pit so that the anchor cage becomes at least partially embedded in the material, which is allowed to cure to form a rigid body. A connecting element is selectively engaged with the upper flange and an actuating element is positioned in operative relation with the connecting element, the connecting and actuating elements positioned in non-contact relation with the anchor bolts. The actuating element is actuated relative to the connecting element to raise the upper flange from the rigid body into a leveled position. A second cementitious material is directed into a space beneath the raised upper flange and is allowed to cure to form a support layer.
