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: A control system for a combustor system including a plurality of can combustors, each can combustor accommodating combustion of a plurality of combustion fluids in a combustion chamber thereof is provided. The control system may include a calculator calculating: a) a pressure drop for each respective can combustor of the plurality of can combustors between a selected combustion fluid upstream of the combustion chamber and a combustion flow within the combustion chamber of the respective can combustor, and b) a differential between the respective pressure drop for each of the plurality of can combustors and an average pressure drop across all of the plurality of can combustors. The differentials identify can-to-can variation. A controller can modify a combustion parameter of at least one can combustor to reduce the differential for the at least one can combustor. The system can work iteratively to reduce can-to-can variation.

Abstract: A power plant includes a turbine disposed downstream from a combustor. The turbine includes an extraction port that is in fluid communication with a hot gas path of the turbine and which provides a flow path for a stream of combustion gas to flow out of the turbine. An exhaust duct is disposed downstream from the turbine and receives exhaust gas from the turbine. An ejector coupled to the extraction port and to an air supply cools the stream of combustion gas upstream from the exhaust duct. The cooled combustion gas flows into the exhaust duct at a higher temperature than the exhaust gas. The cooled combustion gas mixes with the exhaust gas within the exhaust duct to provide a heated exhaust gas mixture to a heat exchanger disposed downstream from the exhaust duct. The heat exchanger may extract thermal energy from the exhaust gas mixture to produce steam.

Abstract: A power plant includes a turbine having a plurality of turbine stages and an extraction port in fluid communication with one or more of the turbine stages. The extraction port provides a flow path for a stream of combustion gas to flow out of the turbine. An exhaust duct is disposed downstream from the turbine and receives exhaust gas from the turbine. The exhaust duct is fluid communication with the extraction port. A coolant injection system injects a coolant into the stream of combustion gas to provide cooled combustion gas to the exhaust duct. The cooled combustion gas flows into the exhaust duct at a temperature that is higher than a temperature of the exhaust gas, thereby increasing the temperature of the exhaust gas within the exhaust duct. The increase in thermal energy may be used to produce steam downstream from the exhaust duct.
