METHOD OF REPOWERING A WIND TURBINE

原文（中国語）

According to a first aspect of the present invention there is provided a method of repowering a horizontal-axis wind turbine The wind turbine comprises a rotor rotatably mounted to a nacelle, the rotor comprising a plurality of used first wind turbine blades connected to a hub, and each blade comprising a blade shell. Each blade extends in a radial direction from a blade root to a blade tip and in a chordwise direction between a leading edge and a trailing edge. The rotor defines a rotor axis and a first rotor diameter. The method comprises increasing the rotor diameter such that the rotor defines a second rotor diameter that is greater than the first rotor diameter. The method further comprises attaching a connecting fixture to each blade, each connecting fixture defining a connection point for connecting a blade connecting member to the blade. The method further comprises connecting a blade connecting member between corresponding connection points of a pair of wind turbine blades such that each blade is connected to at least one other blade by a blade connecting member.
