A WIND TURBINE PLANT OR CLUSTER WITH VERTICAL AXIS WIND TURBINES

摘要

A wind turbine plant comprises a common turbine support platform (14) supporting at least two vertical axis wind turbines (12 i ) horizontally spaced apart from one another. A swivel device (24) supports the common turbine support platform (14), so that the latter is swivellable about a substantially vertical swivel axis (18). Each of the turbines (12 i ) includes a substantially vertical shaft (44 i ) and at least three wing-shaped turbine blades circumferentially distributed around the vertical shaft (44 i ). The wing-shaped turbine blades of both turbines (12i) are exposed to the wind in the space between the vertical shafts (44i) of the two neighbouring turbines (12i). The rotation diameters of the two neighbouring turbines (12i) are separated by a horizontal distance s that is between 0.2*dmax and 1.5*dmax, where dmax is the largest rotation diameter of the two vertical axis wind turbines (12). Two neighbouring vertical axis wind turbines (12 i ) are designed for having opposite directions of rotation.
