The invention relates to wind-power engineering. The wind-power plant comprises a wind turbine which is disposed on a mast and has a rotor, an electrical current generator and an energy accumulator which is in the form of a receiver disposed in a cavity of the mast, at least two first and second pneumatic cylinders which are fixed immovably and symmetrically on the mast and have flexible membranes, and a third pneumatic cylinder which is kinematically connected to the rotor of the electrical current generator. The wind turbine, which is mounted at the top of the mast, has a vertical rotating shaft which is manufactured in the form of a crank mechanism with a rotating section, to which push rods are kinematically connected by one end. The other ends of the push rods are connected to the membranes of the first and second pneumatic cylinders, respectively. The first and second pneumatic cylinders contain a valve for connecting each of the above-mentioned pneumatic cylinders to the receiver cavity, and an idling valve for changing the level of load on the wind turbine. The plant is equipped with a control system which is intended for opening and closing the idling valves of the pneumatic cylinders.

6. WOWO/2014/170232 - A WIND TURBINE BLADE REPAIR METHOD23.10.2014
B29C 73/02
PCT/EP2014/057401LM WP PATENT HOLDING A/SHAAG, Michael Drachmann
A repair solution for a wind turbine blade is described. The repair solution includes the application of a layer of viscous coating material to the section of the blade to be repaired, which is cured to form a repaired surface. The layer of viscous coating material may be temporarily covered during the curing process using a film of Low Surface Energy material, to prevent defects in the repaired surface from dust, insects, etc. Additionally or alternatively, a temporary shield may be erected adjacent the curing layer of coating material, to allow for the control of the temperature and/or humidity levels of the region adjacent the curing material, to provide for more effective control of the curing process and to allow for repairs to be carried out for a wider process window.
