A method for operating a wind farm having a first wind power installation and a second wind power installation, to an associated wind power installation and to an associated wind farm. The second wind power installation is located in the wake of the first wind power installation in at least one wake wind direction. A tip-speed coefficient is determined from the ratio of a second tip-speed ratio of the second wind power installation and a first tip-speed ratio of the first wind power installation and a pitch-angle coefficient is determined from the ratio of a second pitch angle of the second wind power installation and a first pitch angle of the first wind power installation. The method comprises: determining a turbulence metric, in particular a turbulence intensity, at the second wind power installation; operating the first wind power installation and the second wind power installation in the wake wind direction in a part-load range, wherein the tip-speed coefficient and/or the pitch-angle coefficient are/is a function of the turbulence metric at the second wind power installation and are/is greater than one.
A method for operating a wind farm having a first wind power installation and a second wind power installation, wherein the second wind power installation is located in a wake of the first wind power installation in at least one wake wind direction, the method comprising:
A wind power installation, wherein the wind power installation is located in a wake of a further wind power installation in at least one wake wind direction, wherein a tip-speed coefficient is determined from a ratio of a tip-speed ratio of the wind power installation to a tip-speed ratio of the further wind power installation and wherein a pitch-angle coefficient is determined from a ratio of a pitch angle of the wind power installation to a pitch angle of the further wind power installation, the wind power installation comprising:
A wind farm comprising:
