Abstract: The present invention relates to a vertical wind turbine (1) with a plurality of vertical blades (7), which are each fastened to a respective vertical blade axis (26), are each such that they are motor-driven pivotable around a respective blade rotation axis (C7) independently of one another and are supported rotatable on a common circular path (K) around a vertical rotor rotation axis (C2), and to a method for operating the vertical wind turbine (1), wherein angular positions of vertical blades (7) of the vertical wind turbine (1), which are each driven around a respective vertical rotor blade axis (26), are predetermined. According to the invention, the vertical wind turbine (1) is operated in a particularly efficient and material-protecting way in that the angular positions of the blades (7) are continuously controlled through a direct drive of each of the blades (7) by means of a respective pitch motor (27) positioned concentrically to the blade axis (26).

Abstract: A vertical wind turbine with a plurality of vertical blades, which are each fastened to a respective vertical blade axis, such that they are pivotable around a respective blade rotation axis (C7) independently of one another, and are supported rotatable on a common circular path (K) around a vertical rotor rotation axis (C2), and a method for operating the vertical wind turbine, wherein pitch angles (?) of vertical blades of the vertical wind turbine, which are driven around a respective vertical blade axis, are predetermined. The pitch angle (?), at least in a partial load mode of the vertical wind turbine (1), is controlled such that the blades (7) rotate with an essentially constant tip speed ratio (?).
Abstract: A vertical axis wind turbine includes two or more cells arranged one above the other along a vertical machine axis, wherein each of the cells includes a plurality of vertical blades which are arranged within the cell distributed on a concentric circle about the machine axis and which are connected so as to be able to move together on this circle and which are rotationally fixed with a main shaft, and wherein the blades in the cell are each individually mounted so as to be able to rotate about a vertical axis of rotation which in particular runs internally through them.
Abstract: A vertical axis wind turbine includes two or more cells arranged one above the other along a vertical machine axis, in which each of the cells includes a plurality of vertical blades which are arranged within the cell distributed on a concentric circle about the machine axis and which are connected so as to be able to move together on this circle and which are rotationally fixed with a main shaft, and in which the blades in the cell are each individually mounted so as to be able to rotate about a vertical axis of rotation which in particular runs internally through them. Assigned to each of the blades are means by which the blade is made to adopt, a rotational position, about its axis of rotation, which is predetermined and can be changed at any time.
Abstract: The invention relates to a wind power plant, comprising a rotor that can be rotated about a vertical axis, said rotor between two horizontal bearing planes disposed at a distance on top of each other comprising a plurality of rotor blades, which are disposed distributed on a circumferential circle, can each be pivoted about a vertical pivot axis, and the pivot range of which is delimited on both sides by a stop. In such a wind power plant, an improvement in the energy yield, while simultaneously ensuring another operation, is enabled in that the width of the rotor blades is smaller than approximately ? the radius of the circumferential circle.
