Embodiment Construction

[0017] Reference will now be made in detail to embodiments of the invention, one or more examples of which are illustrated in the accompanying drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For example, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.

[0018] figure 1 A perspective view of one embodiment of an existing wind turbine 10 is shown. As shown, wind turbine 10 includes a tower 11 extending from a support surface 14 , a nose 16 mounted on tower 11 , and a rotor 18 coupled...

Abstract

Methods for refurbishing a wind turbine are provided. A method includes removing an existing machine head and existing top tower section from the wind turbine. The wind turbine further includes a lower tower section, the lower tower section comprising a top flange, the top flange defining a first plurality of fastener holes disposed in a first hole pattern. The method further includes connecting anew machine head and new top tower section to the wind turbine. The new top tower section comprises a bottom flange, the bottom flange defining a second plurality of fastener holes disposed in a second hole pattern. The second hole pattern matches the first hole pattern.

Description

technical field [0001] The present disclosure relates generally to wind turbines, and more particularly to methods for retrofitting wind turbines. Background technique [0002] Wind power is considered to be one of the cleanest and most environmentally friendly energy sources currently available, and wind turbines have attracted increasing attention in this regard. A modern wind turbine typically includes a tower, a generator, a gearbox, a nose, and a rotor including one or more rotor blades. The rotor blades capture kinetic energy from the wind using known airfoil principles and transfer the kinetic energy through rotational energy to turn a shaft that couples the rotor blades to a gearbox or, if a gearbox is not used, directly to a generator. A generator then converts the mechanical energy into electrical energy that can be deployed to the utility grid. [0003] Wind turbine technology is advancing rapidly. Accordingly, as the technology used in existing wind turbines b...
