Abstract: A system includes a compressor having a compressor inlet, a turbine having a plurality of stages disposed within a turbine casing, and a turbine extraction gas (TEG) heating system. The turbine is configured to drive the compressor via expansion of combustion products through the plurality of stages. The TEG heating system includes a turbine gas extraction system coupled to the turbine casing and to the compressor inlet. The turbine gas extraction system is configured to receive a portion of the combustion products as a turbine extraction gas (TEG) from the turbine. The TEG is received through the turbine casing, the TEG heating system is configured to supply a heated flow to the compressor inlet, and the heated flow includes the TEG.

Abstract: A power generation system includes: a first gas turbine system including a first turbine component, a first integral compressor and a first combustor to which air from the first integral compressor and fuel are supplied, the first combustor arranged to supply hot combustion gases to the first turbine component, and the first integral compressor having a flow capacity greater than an intake capacity of the first combustor and/or the first turbine component, creating an excess air flow. A second gas turbine system may include similar components to the first except but without excess capacity in its compressor. A control valve system controls flow of the excess air flow from the first gas turbine system to the second gas turbine system. A storage vessel may be coupled to the excess air flow path for augmenting the excess air flow with additional air during a peak demand period.

Abstract: A gas turbine system includes a compressor protection subsystem; a hibernation mode subsystem; and a control subsystem that controls the compressor subsystem and the hibernation subsystem. At partial loads on the turbine system, the compressor protection subsystem maintains an air flow through a compressor at an airflow coefficient for the partial load above a minimum flow rate coefficient where aeromechanical stresses occur in the compressor. The air fuel ratio in a combustor is maintained where exhaust gas emission components from the turbine are maintained below a predetermined component emission level while operating at partial loads.

Abstract: A system for controlling gas turbine output for a gas turbine power plant is disclosed herein. The power plant includes a gas turbine including a combustor downstream from a compressor, a turbine downstream from the combustor and an exhaust duct downstream from the outlet of the turbine. The exhaust duct receives exhaust gas from the turbine outlet. The system further includes an exhaust damper operably connected to a downstream end of the exhaust duct. The exhaust damper increases backpressure at the turbine outlet and restricts axial exit velocity of the exhaust gas exiting the turbine outlet when the exhaust damper is partially closed. A method for controlling gas turbine output is also provided herein.

Abstract: This disclosure provides systems, methods, and storage medium for storing code related to controlling turbine shroud clearance for operational protection. The disclosure includes a multi-stage turbine and a protection system. The multi-stage turbine includes a stage of airfoils with a distal shroud, a casing adjacent the distal shroud and defining a clearance distance between the distal shroud and the casing, and a clearance control mechanism that controllably adjusts the clearance distance based upon receiving a clearance control signal. The protection system has an operational limit value related to a failure mode and provides the clearance control signal to the clearance control mechanism. The protection system receives operational data related to the multi-stage turbine and modifies the clearance control signal based on the operational limit value to increase the clearance distance.
