摘要
A method and a device are disclosed for the safe operation of a gas turbine plant, whose operation is both controlled by at least one process controller, which at least triggers and/or influences operationally relevant processes of the gas turbine plant, and is also monitored by a separate protection unit that is operated independently of the process controller on the basis of at least one first limit value for a safety-relevant operating parameter, wherein the gas turbine plant is subjected to an emergency switch-off once the at least one first limit value is exceeded. In that in the case of a defined transient operating state of the gas turbine plant that can be detected by the protection unit, the at least one first limit value of the safety-relevant operating parameter is raised to a second limit value, wherein the gas turbine plant is protected by an emergency switch-off of the gas turbine plant once said second limit value is exceeded. Furthermore, secondary protective functions can be carried out in the process controller.
