Abstract
Method for controlling a wind power installation () which has rotor blades () whose blade angle is adjustable and which can be operated at a variable speed using speed control, wherein the speed control is prepared to control the speed to a variable target speed value, comprising the steps of evaluating a test criterion for predicting an emerging overspeed, predicting an overspeed (n) on the basis of the at least one test criterion, and changing the speed control if an overspeed (n) has been predicted. Proposed are techniques that avoid an excessive increase in the rotor speed even in the event of strong wind speed increases. In particular, proposed are techniques that avoid reaching an overspeed that leads to shutdown, but without increasing the operating loads too much.
