Abstract: A method for operating a gas turbine plant having a gas turbine and an electric generator driven by the gas turbine. The method includes detecting an instantaneous power of the gas turbine plant; comparing the detected instantaneous power with a power limit value; and limiting the instantaneous power when the result of the comparison is that the detected instantaneous power is equal to or greater than the power limit value. A step of detecting at least one operating parameter of the gas turbine plant and a step of determining the power limit value as a function of the at least one detected operating parameter are then implemented, wherein the at least one operating parameter of the gas turbine plant includes an ambient pressure and the power limit value is increased when the ambient pressure increases.

Abstract: A method for testing an overspeed protection apparatus of a single-shaft system that includes: a) operating the system at nominal speed and under electrical load, wherein the load is selected to be low enough that, after dropping the load, the speed of the system rises such that the speed remains below steam turbine threshold speed lower than gas turbine threshold speed, such that first overspeed protection is triggered when the speed of the steam turbine reaches the steam turbine threshold speed, and second overspeed protection is triggered when the speed of the gas turbine reaches the gas turbine threshold speed; b) dropping the load; c) increasing the mass flow of the steam introduced into the steam turbine and/or of the fuel introduced into the gas turbine such that the speed of the steam turbine reaches the steam turbine threshold speed; d) testing whether the first overspeed protection is triggered.
