A method of monitoring a power generation system that includes a steam turbine that is coupled to a gas turbine engine. The method includes calculating, by a control system, a gas turbine engine power output that is based at least in part on a predefined power generation system power output and a predefined steam turbine power output. The power generation system is operated to generate a power output that is approximately equal to the predefined power generation system power output. A signal indicative of a sensed operating power output of the gas turbine engine is transmitted from a sensor to the control system. A condition of the steam turbine is determined based at least in part on the sensed operating gas turbine engine power output and the calculated gas turbine engine power output.

Embodiments of the present invention have the technical effect of automatically testing an overspeed protection system of a powerplant machine comprising a shaft and integrated with a safety control system. An embodiment of the present invention may automatically test the overspeed protection system while the powerplant machine is in the process of shutting down. Another embodiment of the present invention may automatically test the overspeed protection system of the powerplant machine by adjusting the speed of a shaft while operating at full-speed-no-load.
