In a first aspect of the present invention there is provided a method of repowering a horizontal-axis wind turbine comprising a tower, a nacelle located rotatably at the apex of the tower, and a rotor having a hub and at least three used blades mounted pitchably to the hub and extending radially therefrom, the method comprising the steps of uninstall the at least three used blades from the hub, install at least three repower blades to the hub, each repower blade extending between a root and a tip, and each repower blade further comprising a connection point located between the root and the tip, install a plurality of blade connecting members, each blade connecting member being connected between corresponding connection points of a pair of repower blades; and install a tensioning system with the hub, the tensioning system being configured to adjust a tension in each blade connecting member.
A method of repowering a horizontal-axis wind turbine comprising a tower, a nacelle located rotatably at the apex of the tower, and a rotor having a hub and at least three used blades mounted pitchably to the hub and extending radially therefrom, the method comprising:
The method according to claim to 4, wherein the tensioning system comprises a system for powering the linear actuators which is integrated with a blade pitch system of the hub by a shared system for powering the linear actuators.
(canceled) Please add the following new claims:
