Abstract

A rotor blade of a wind turbine, to an associated wind turbine, to an associated wind farm and to associated methods. The rotor blade has a leading edge and a trailing edge and extends in a longitudinal direction of the rotor blade between a root end and a tip end, wherein a direct connection between the leading edge and the trailing edge is referred to as a chord line, wherein the rotor blade has serrations in the region of the trailing edge at least in some section or sections, wherein each of the serrations has a base line, which is arranged at the trailing edge, and an end point, which is furthest away from the base line, which together span a plane of the serration, wherein an angle between the plane of at least one of the serrations and the profile chord of the rotor blade is formed as a function of at least one environmental parameter at the installation location of the wind turbine.
