1. A wind power installation, comprising:
at least one sensor device;
an azimuth bearing having an azimuth gearing; and
at least one azimuth drive coupled to an azimuth gear mechanism corresponding to the azimuth gearing,
wherein the azimuth gear mechanism comprises a drive pinion rotatable about a pinion axis,
wherein the drive pinion is configured to engage in the corresponding azimuth gearing of the azimuth bearing,
wherein the pinion axis has a predefined reference orientation, and
wherein the at least one sensor device is configured to detect a deviation of an orientation of the pinion axis relative to the predefined reference orientation.
