1. WO/2015/110138 PITCH BEARING CONSTRUCTION COMPRISING SPHERICAL PLAIN BEARINGSWO30.07.2015
F03D 11/00
PCT/EP2014/051053AKTIEBOLAGET SKFKLEINMEULEMAN, Peter
The present invention resides in a bearing construction (200) for enabling angular adjustment of a wind turbine blade (220) relative to a wind turbine hub (210), comprising a dynamic frame and a static frame, whereby the static frame has static frame legs (241) which penetrate through openings between dynamic frame legs (231, 232) of the dynamic frame. The dynamic frame may form part of the turbine blade or the blade may be attachable to the dynamic frame. Similarly, the static frame may form part of the hub or is attachable to the hub. The bearing construction (200) further comprises first and second axially spaced shaft sections (270, 280), each of which forms part of one of the dynamic and static frames. First and second radial spherical plain bearings (250, 260) are mounted on the first and second shaft sections respectively, for rotationally supporting the dynamic frame relative to the static frame. According to the invention, one of the first and second shaft sections is a tapered shaft section (280). Further, the corresponding spherical plain bearing (260) has a tapered bore and has an axial width that is greater at one side of a reference line than at an opposite side. The reference line is perpendicular to a rotation axis (205) of the bearing and passes through a spherical centrepoint of the bearing (260).

3. WO/2015/110276 GRID DETECTION MODULE FOR A WIND TURBINE, AND METHOD FOR DETERMINING THE GRID FREQUENCYWO30.07.2015
G01R 23/02
PCT/EP2015/050048SENVION SELETAS, Heinz-Hermann
The invention relates to a method for determining the grid frequency, in which a voltage curve (U1) of a first phase (281) of the grid (16) and a voltage curve (U2) of a second phase (282) of the grid (16) are measured. A linear combination (UXi) is formed from the voltage curve (U1) of the first phase (281) and the voltage curve (U2) of the second phase (282). The time interval between a first voltage value of the linear combination (UXi) and a second voltage value of the linear combination (UXi) is determined. The invention also relates to a grid detection module which is suitable for carrying out the method. By virtue of the invention, it is possible to determine the grid frequency with shorter cycles and/or with increased accuracy.

4. WO/2015/113011 DUAL PURPOSE SLAT-SPOILER FOR WIND TURBINE BLADEWO30.07.2015
F03D 7/02
PCT/US2015/012979SIEMENS AKTIENGESELLSCHAFTDIXON, Kristian R.
An aerodynamic slat (30) mounted over a forward suction side (40) of a wind turbine blade (22) and a mechanism (51A-F) that closes or reduces a gap (31) between slat and blade. The slat may pivot to reduce the gap, or the gap may be reduced by a device such as an extendable gate (58), or butterfly plate (59), or damper plate (60). Control logic (64) activates an actuator (70) of the mechanism to close or reduce the gap when wind conditions meet or exceed a predetermined criterion such as a rated wind condition. This reduces wind loading on the blade by separating airflow (53) over the suction side of the blade downstream of the slat. The blades can then maintain a higher angle of attack during rated wind conditions than in the prior art, allowing them to stall in gusts sooner to limit peak aerodynamic loads.

5. WO/2015/110580 GUYED TOWER STRUCTURE FOR A WIND TURBINE WITH HIGH TORSIONAL RIGIDITYWO30.07.2015
