The invention relates to a method for controlling a wind power installation which has a rotor having rotor blades that are adjustable in terms of their blade angle, and having a rotor diameter, wherein the rotor is able to be operated at a variable rotor rotating speed; and a region in which the rotor blades move forms a danger zone for birds and bats, the method comprising the following steps: checking whether a bird or bat approaching the wind power installation is an endangered bird and if an endangered bird has been identified, detecting a bird position as the current position of the endangered bird identified; and controlling the rotor rotating speed as a function of the bird position in relation to the wind power installation; wherein the rotor rotating speed is reduced in multiple stages or continuously as the distance of the bird position from the wind power installation decreases. The invention is intended to propose a solution in which a wind power installation poses the lowest possible risk to endangered species of birds and bats while at the same time offering the best possible yield. The intention is to at least propose an alternative to the solutions known to date.

Method for controlling a wind power installation so as to protect birds and bats

The present disclosure relates to a method for operating a wind power installation, to an associated wind power installation and to a wind farm. The method comprises the following steps: determining at least two, preferably at least three and particularly preferably all the environmental parameters of the environment of the wind power installation selected from the list consisting of: turbulence intensity, air density, air temperature and shear; providing boundary conditions for operating the wind power installation, the boundary conditions containing at least one from a load boundary condition, a noise level boundary condition and a power boundary condition; adapting an operational control, in particular an operating point and/or an operating characteristic, of the wind power installation on the basis of a combination of the changes in the determined environmental parameters taking into consideration the boundary conditions.
