摘要： A combustion turbine power generation system includes a modified simple cycle combustion turbine power generation system optimized for a "hot" stand-by reserve mode of operation and having a power shaft assembly including a compressor, an expansion turbine, and a double-ended motor/generator between the compressor and the turbine. The motor/generator has a turbine driving clutch structure on one end thereof and a compressor driving clutch structure on the other end thereof. A combustor feeds the expansion turbine. The power generation system includes an additional system having a boost compressor, an intercooler feeding cooled air to the boost compressor an electric motor for driving the boost compressor, and aftercooler downstream of the boost compressor. A compressed air energy storage is downstream of the aftercooler. The additional system is integrated with the modified simple cycle combustion turbine power generation system to provide (i) a primary mode of operation--a hot stand-by mode, when the plant is ready to deliver an emergency power at full turbine power of specified duration within a few seconds; (ii) a cold start-up mode of operation, when the plant is ready to deliver an emergency power at full turbine power of specified duration within a few minutes, depending on the specifics of the turbine design, (iii) an emergency power supply mode, when the plant provides emergency power at full turbine power of specified duration; (iv) a combustion turbine emergency power supply mode, when the plant provides approximately 50% of full turbine power of unlimited duration during long term interruptions of the power supply; and (v) a storage charging mode of operation to charge the air storage.
