1. A wind power plant having one or more turbines the rotation axis or axes of which are disposed vertically, each turbine including a rotor (3) having a plurality of orientable blades (4, 23, 36) disposed parallel to the rotor axis and the incidence angle of which relative to the direction of the incoming wind is modified in the course of rotation of the rotor (3) by cyclic incidence varying appliance (5, 6) consisting of a linkage system (6) fast with the rotor (3) - or consisting of electric or hydraulic servo controls - and actuated in turn by a fixed central cam unit (5) fixed to the supporting frame (17), shrouds (1) for guiding the wind to the active blades (4, 23, 36) for masking the contrarotating side of the rotor (3) and for adjusting the wind intake by means of movable flaps (21), and a mechanical drive (10) for connecting it to one of the adjacent turbines in the event of plurality thereof, characterised by the arrangement of the following features : a) the profile of said fixed central cam (5) is of variable geometry b) a locking up brake (9) is connected to the rotor (3) c) the above mentioned rotor (3) comprises at the upper and lower ends a plurality of horizontal arms (31) carrying said blades (4, 23, 36) of curved cross-section the shape of which corresponding with an aerodynamic airfoil.
