摘要： A method (100) includes determining, via a processor (39), a commanded temperature rate for a component of a steam turbine system (41). The method (100) further includes determining, via the processor (39), a measured temperature rate for the component of the steam turbine system (41). The method (100) additionally includes determining, via the processor (39), a variable multiplier based at least in part on the commanded temperature rate and the measured temperature rate. The method (100) also includes deriving, via the processor (39), a multiplied temperature rate command by applying the variable multiplier to the commanded temperature rate.

摘要： A control system (170) is provided. The control system includes at least one sensor (204) configured to detect at least one operating condition within at least one first boiler (120) and at least one second boiler (110). A controller is coupled to the sensor and is configured to determine a fluid pressure set point and/or a fluid temperature set point for the first and second boilers based on the operating condition detected for each. The controller is also configured to maintain a fluid pressure and/or a fluid temperature within the first and second boilers to be approximately equal to the determined fluid pressure set point and the fluid temperature set point for each of the first boiler and second boiler, respectively, prior to fluid flow being channeled and/or during the channeling of fluid flow from the first boiler and/or the second boiler to a steam process and/or at least one steam turbine engine (104).

摘要： A control system for operating a steam turbine (20) in combined-cycle power system (10) is provided. The control system is configured to channel a first amount of steam from a first steam generator (18) to a steam turbine to facilitate powering the steam turbine, generate a second amount of steam within a second steam generator (118) that is coupled in flow communication with the steam turbine (20), calculate a predicted stress level within the steam turbine in the event the second amount of steam is channeled from the second steam generator (118) into the steam turbine (20), determine an initiation time at which to channel the second amount of steam into the steam turbine (20) such that the calculated predicted stress level will not exceed a predetermined stress limit of the steam turbine (20), and automatically channel the second amount of steam from the second steam generator (118) to the steam turbine (20) at the determined initiation time.

摘要： An apparatus and method for steam cooling a gas turbine. An intermediate-pressure drum 106 of a recovery boiler supplies outlet steam, as a cooling steam, to a combustor 117 through a steam channel 116. The flow rate of steam guided into the combustor 117 is adjusted through opening or closing of a first flow control valve 120 by a controller 125 such that the pressure of the intermediate-pressure drum 106 becomes a set value set according to a load status of a gas turbine 101. A required amount of steam according to the load status of the gas turbine 101 is fed to the combustor 117. Thus. the flow rate of steam guided into the combustor 117 is controlled by adjustment of the existing first flow control valve 120 for maintaining the pressure of the intermediate-pressure drum 106 in a predetermined state, without the need to provide an expensive valve device in the steam channel 116.
