1. A flange (1) of a wind turbine,wherein the flange (1) comprises a flange plate (2) connected to a part (3) of the wind turbine;

  • wherein the flange plate (2) is connected with the part (3) of the wind turbine via an edge (4) to form an L-shaped flange (1);

    wherein the flange plate (2) comprises a connecting side (5) detachably connected to a corresponding part;

    wherein the flange plate (2) comprises a plurality of holes (6) for use with connecting means (14) when the flange (1) is connected to the counterpart;

    it is characterized in that the preparation method is characterized in that,a recess (7) is arranged in the surface of the connection side (5) and between the edge (4) of the flange plate (2) and the plurality of holes (6),wherein the recess (7) is arranged in the flange plate (2) such that the distance between the edge (4) and the recess (7) is larger than the thickness of the part (3) of the turbine, wherein the thickness of the material of the flange plate (2) is reduced by the recess (7) to allow flexible deformation of the flange plate (2) under high loads such that the flange connection is allowed to open in the area of the recess (7) to reduce fatigue loads in the area of the hole (6) of the flange plate (2).
