Abstract
Provided herein is a wind energy installation including a generator for production of electrical energy, a rotor which drives the generator and has variable pitch rotor blades and a central control device, and individual pitch devices provided individually for the rotor blades. The individual pitch devices may include an adjustment drive, a communication link to the central control device and a regulator, the rotor blades being adjustable in order to slow down the wind energy installation to a shut-down position. The individual pitch devices may also include a disturbance situation detector which is designed to identify abnormal operating states and to move the rotor blades to a shut-down position. Also provided herein is the method of operating such a wind energy installation.
