  • Power generation system and methods for monitoring operation of same
    Patent number: 9003809
    Abstract: 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.

  • Method and system for testing an overspeed protection system of a powerplant machine
    Patent number: 8365583
    Abstract: 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.

  • SYSTEMS AND APPARATUS FOR A FUEL CONTROL ASSEMBLY FOR USE IN A GAS TURBINE ENGINE
    Publication number: 20110167782
    Abstract: A fuel control assembly for use in a gas turbine engine. The fuel control assembly includes a first trip device configured to selectively release a fluid pressure from a trip fluid system. At least one gas fuel control valve is coupled to the first trip device. The gas fuel control valve includes a second trip device for moving the gas fuel control valve to a safe position during a purge air operation.
