Abstract

A method of operating a wind energy installation having a rotor with at least one rotor blade that is angularly adjustable by an adjustment drive. In response to the occurrence of at least one special operating case, in particular at least one malfunction case, the rotor blade is adjusted in a direction of a shutdown position by the adjustment drive. In the shutdown position, a supply of energy from an energy storage device to the adjustment drive is switched off and/or a pitch brake for holding the rotor blade in its current position is closed. In response to at least one activation signal, the rotor blade is adjusted by the adjustment drive in an adjustment mode of operation while the special operating case is still ongoing, in particular while the malfunction case is still ongoing.
