Title: Combustion turbine power plant operable at full power using supplemental compressed air

Abstract: A method of operating a combustion turbine power generation system and derivatives thereof. The method provides at least one combustion turbine assembly including a compressor, an expansion turbine operatively associated with the compressor, a generator coupled with the expansion turbine; a combustor feeding the expansion turbine; flow path structure fluidly connecting an outlet of the compressor to an inlet of the combustor; a supplemental compressor structure; connection structure fluidly connecting an outlet of the supplemental compressor structure to a point upstream of the combustor, and valve structure associated with the connection structure to control flow through the connection structure. The valve structure is controlled selectively permit one of the following modes of operation: (a) a combustion turbine mode of operation wherein air compressed from the compressor moves through the flow path structure to the combustor feeding the expansion turbine such that the expansion turbine drives the generator, and (b) a power augmentation mode of operation wherein supplemental compressed air from the supplemental compressor structure is supplied through the connection structure and is directed to the combustor feeding the expansion turbine, in addition to compressed air passing through the flow path structure to the combustor feeding said expansion turbine, which increases mass flow of compressed air and gas to the expansion turbine.
