Abstract

A management system for controlling a wind turbine according to prescribed rules and a safety system, separate from the management system, for monitoring the wind turbine on the basis of operational characteristic values, wherein the safety system transfers the wind turbine to a safe plant state independently of the management system if safety-critical operational characteristic values violate safety parameters stored in the safety system, in order to change at least one safety parameter stored in the safety system a parameter block comprising the at least one safety parameter and at least two safety features is supplied to the safety system and accepted by the safety system only after a positive check on the safety features, wherein the check on at least one of the safety features requires comparison against check information available directly on the wind turbine.
