摘要： A hybrid power plant system (100) including a gas turbine system (109) and a coal fired boiler system (103) inputs high oxygen content gas turbine flue gas into the coal fired boiler system, said gas turbine flue gas also including carbon dioxide that is desired to be captured rather than released to the atmosphere. Oxygen in the gas turbine flue gas is consumed in the coal fired boiler, resulting in relatively low oxygen content boiler flue gas stream to be processed. Carbon dioxide, originally included in the gas turbine flue gas, is subsequently captured by the post combustion capture apparatus of the coal fired boiler system, along with carbon diode generated by the burning of coal. The supply of gas turbine flue gas which is input into the boiler system is controlled using dampers and/or fans by a controller based on an oxygen sensor measurement and one or more flow rate measurements.

摘要： This combined cycle gas turbine plant has a gas turbine (104) and a steam turbine (106) mounted on the same shaft. A control system is configured for switching the plant from a rated mode of operation, in which the plant is operated on gas turbine output and steam turbine output, to a reduced load mode of operation, in which the plant is operated on gas turbine output alone. The switch from the rated mode of operation to the reduced load mode of operation occurs if plant demand decreases below a predetermined threshold. The steam turbine is run under full speed no load conditions in the reduced load mode of operation, and is heated using controlled steam admission, to maintain the steam turbine in a heated 'stand-by' state.

摘要： A gas turbine combined-cycle power plant can comprise a gas turbine engine, a heat recovery steam generator, a steam turbine, a fuel regasification system and a Rankine Cycle system. The gas turbine engine can comprise a compressor for generating compressed air, a combustor that can receive a fuel and the compressed air to produce combustion gas, and a turbine for receiving the combustion gas and generating exhaust gas. The heat recovery steam generator is configured to generate steam from water utilizing the exhaust gas. The steam turbine is configured to produce power from steam from the heat recovery steam generator. The fuel regasification system is configured to convert the fuel from a liquid to a gas before entering the combustor. The Organic Rankine Cycle system is configured to cool compressed air extracted from the compressor to cool the gas turbine engine, and heat liquid fuel entering the fuel regasification system.

摘要： A method (110) of controlling an imbalance response in a power plant comprising first and second gas turbine engines and a steam turbine driven by steam generated by exhaust from the first and second gas turbine engines can comprise operating the first gas turbine engine at a first power output (116A), operating the second gas turbine engine at a second power output (116B), monitoring load demand from a power grid operating at a steady state condition (114), detecting a load imbalance on the power grid (120) that causes a deviation from the steady state condition, and adjusting the first power output and the second power output incongruently (128) during the imbalance response to change the first power output and the second power output to match the deviation from the steady state condition depending on contemporaneous efficiency states of the first and second gas turbine engines.

摘要： A method of controlling operation of a first power plant in response to changing power grid conditions can comprise: receiving a power-plant-specific power assignment from an operator of a grid system, monitoring an operating frequency of the power grid relative to a control frequency, operating at least one power generator of the first power plant at the control frequency to provide a local power output to meet the power-plant-specific power assignment under steady state conditions, detecting a load imbalance from the power grid wherein the operating frequency and the control frequency are different, and operating the at least one power generator to provide a power-plant-specific imbalance response wherein the local power output is adjusted based on a power-plant-specific-trait of the first power plant relative to a second power plant working with the operator.

摘要： A power plant system can comprise a first gas turbine having a first efficiency to produce a first exhaust flow, a first electrical generator driven by the first gas turbine, a first heat recovery steam generator to receive the first exhaust flow and generate a first steam flow, a second gas turbine having a second efficiency less than the first efficiency to produce a second exhaust flow, a second electrical generator driven by the second gas turbine, and an exhaust gas conditioning device to reduce temperature of the second exhaust flow, a steam turbine driving a steam electrical generator to receive the first steam flow. The second gas turbine can be selectively operated to generate electricity with the second electrical generator under peak loading conditions when a sum of output from the steam electrical generator and the first electrical generator are less than an electrical demand from a grid.
