Wind turbine and method for operating a wind turbine

A wind turbine, comprising:

• a support structure comprising at least one structural component with at least one fastening portion, and at least one reinforcing element;
• wherein the structural component includes a plurality of fastening holes configured for fastening an operating means;
• wherein the structural component is at least partially dynamically loaded during operation of the wind turbine, and at least one of the plurality of fastening holes lies in a region dynamically loaded during operation of the wind turbine;
• wherein the wind turbine is convertible between at least two states, wherein a first state is an operating state and a second state is a maintenance state;
• wherein, in the operating state, the reinforcing element is screwed to the fastening portion of the structural component to achieve defined pre-stressed screw connections comprising screw fastening means inserted into at least some of the plurality of fastening holes;
• and
• wherein, in the maintenance state, the screw connections are released and the reinforcing element is removed from the structural component of the support structure, whereby an operating means can be connected to the fastening portion of the structural component via the fastening holes.

A method for operating a wind turbine, the wind turbine comprising a support structure including at least one structural component with at least one fastening portion, and at least one reinforcing element, the structural component including a plurality of fastening holes configured for fastening an operating means, the reinforcing element screwed to the fastening portion to achieve defined pre-stressed screw connections comprising screw fastening means inserted into at least some of the plurality of fastening holes, the method comprising:

• transferring the wind turbine from an operating state into a maintenance state by:
• releasing the screw connections that couple the reinforcing element to the structural component, and
• removing the reinforcing element;
• performing maintenance work on the wind turbine;
• and
• transferring the wind turbine from the maintenance state into the operating state by:
• obtaining the reinforcing element or a replacement reinforcing element, and
• connecting the reinforcing element or the replacement reinforcing element to the fastening portion of the structural component by inserting screw fastening means into at least some of the fastening holes and screwing the reinforcing element or the replacement reinforcing element to the fastening portion of the structural component to achieve defined pre-stressed screw connections.
