Abstract:
Embodiments of the invention can include methods and systems for controlling clearances in a turbine. In one embodiment, a method can include applying at least one operating parameter as an input to at least one neural network model, modeling via the neural network model a thermal expansion of at least one turbine component, and taking a control action based at least in part on the modeled thermal expansion of the one or more turbine components. An example system can include a controller operable to determine and apply the operating parameters as inputs to the neural network model, model thermal expansion via the neural network model, and generate a control action based at least in part on the modeled thermal expansion.

US Patent:
8463445, Jun 11, 2013
Filed:
May 28, 2010
Appl. No.:
12/789847
Inventors:
Rajeeva Kumar - Clifton Park NY, US
Erhan Karaca - Clifton Park NY, US
Assignee:
General Electric Company - Niskayuna NY
International Classification:
G05D 9/00
US Classification:
700281, 702 55, 1224481, 137386
Abstract:
A method for controlling a water level of a drum of a heat recovery steam generation system for a combined cycle power plant is provided. The method includes determining an optimum drum water level during start up operation of the heat recovery steam generation system based on a characteristic chart model. The characteristic chart model is generated based on a plurality of vapor pressures of the drum and a plurality of temperatures of drum metal at the time of the start up operation of the heat recovery steam generation system.

System And Method For Controlling Liquid Level In A Vessel

US Patent:
20090159018, Jun 25, 2009
Filed:
Dec 19, 2007
Appl. No.:
11/959554
Inventors:
Charudatta Subhash Mehendale - Niskayuna NY, US
Bruce Gordon Norman - Burnt Hills NY, US
Erhan Karaca - Clifton Park NY, US
Rajeeva Kumar - Clifton Park NY, US
Assignee:
GENERAL ELECTRIC COMPANY - SCHENECTADY NY
International Classification:
F22D 5/26
US Classification:
122451 R
Abstract:
A system includes sensors configured to measure parameters related to a vessel including liquid level, gas flow rate, pressure in the vessel, temperature of the vessel, and feed-liquid flow rate. A signal processing unit receives sensor output signals and generates a first filtered output signal representative of liquid level, a second filtered output signal representative of gas flow rate, a third filtered output signal representative of feed-liquid flow rate, a fourth filtered output signal representative of vessel pressure, and a fifth filtered output signal representative of vessel temperature. A flow demand control unit receives the first filtered output signal and generates an output signal representative of feed-liquid flow demand. A shaping unit receives the second, fourth, and fifth filtered output signal and generates an output signal representative of shaped gas flow rate as a function of pressure, temperature, or combination thereof in the vessel. A liquid level control unit controls the liquid level within predetermined limits by controlling one or more components based on the output signals from the flow demand control unit, the shaping unit, and the third filtered output signal.

US Patent:
20100139392, Jun 10, 2010
Filed:
Dec 8, 2008
Appl. No.:
12/329753
Inventors:
Rajeeva Kumar - Clifton Park NY, US
Karl Dean Minto - Ballston Lake NY, US
Charudatta Subhash Mehendale - Niskayuna NY, US
Erhan Karaca - Clifton Park NY, US
Assignee:
GENERAL ELECTRIC COMPANY - SCHENECTADY NY
International Classification:
G01F 23/00
US Classification:
73290 R
Abstract:
A level control system for controlling a liquid level in a vessel containing a two-phase fluid includes a plurality of sensors configured to measure parameters related to the vessel. The parameters include liquid level in the vessel, vapor flow rate leaving the vessel, pressure in the vessel, temperature of the vessel, and feed-liquid flow rate entering the vessel indicative of a state of the vessel. A predictive controller is configured to receive output signals from the plurality of sensors and predict a volume of liquid over a predetermined time period in the vessel based on output signals from the plurality of sensors and a variation in pressure, thermal load, or combinations thereof in the vessel. The controller is configured to generate a liquid level set point of the vessel based on the predicted volume of liquid in the vessel; and further control a liquid level in the vessel based on the generated liquid level set point by manipulating one or more control elements coupled to the vessel.

System And Method For Controlling A Fuel Supply Associated With A Turbomachine

View page
US Patent:
20120234413, Sep 20, 2012
Filed:
Mar 18, 2011
Appl. No.:
13/051509
Inventors:
Fabien Thibault Codron - Simpsonville SC, US
Michael John Mariani - Greer SC, US
Erhan Karaca - Clifton Park NY, US
International Classification:
F04B 49/00
US Classification:
13756511
Abstract:
Embodiments of the present invention incorporate a relatively slow acting valve to throttle the fuel flow through the compressor. Embodiments of the present invention seek to reduce the need for recirculating compressed fuel that is not needed by the turbomachine. This may increase the net power output and efficiency of a turbomachine-fuel gas compressor system.
