摘要： The present invention relates to a group of wind power plants for positioning in approximately the same wind climate, comprising at least a first and at least a second wind power plant, where the first wind power plant exhibits maximised power output within a first interval of wind speeds, and the second wind power plant is designed to exhibit maximised power output within a second interval of wind speeds which is different from and starting from lower wind speeds than the first wind speed interval to the effect that the total power output of the group of wind power plants is increased at lower wind speeds. Moreover, the invention relates to a method of designing a group of wind power plants in accordance with the above. This can be accomplished eg by designing the supplementary wind power plant(s) with a larger rotor area and with a lower cut-out wind speed or, alternatively, by using a wind power plant without power-regulating means. Hereby it is accomplished that the power production of the group becomes more uniform and not so dependent on the current wind speed. The smaller power output from the supplementary wind power plants is completely or partially balanced by, on the one hand, the lower production and operating costs of the turbine and, on the other, the higher price on electricity.

摘要： Wind turbine blade (10) including adjustable lift-regulating means (12, 13, 15, 17, 19, 21) arranged on or at the surface of the wind turbine blade (10), said lift-regulating means being provided with activating means by means of which they can be adjusted and thus alter the aerodynamic properties of the blade (10). The lift-regulating means (12, 13, 15, 17, 19, 21) and the activating means are adapted and arranged such that by activation of the activating means, the lift can be reduced in a zone extending in the longitudinal direction of the blade (10) from a first position adjacent the blade tip (14) to a second position between the first position and the blade root (16) and this second position is variable in the longitudinal direction of the blade (10) by adjusting the activate means. The lift-regulating means are formed of at least one flexible flap (12, 13, 15, 17, 19, 21). The invention further relates to a wind turbine rotor including such wind turbine blades, to a wind turbine and to a method of controlling the wind turbine.
