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.

[ What is claimed is:] [1.]1. A method of operating a combustion turbine power generation system and derivatives thereof, the system including at least one combustion turbine assembly for electrical power generation including at least one compressor optimized for full rated power of the combustion turbine assembly, at least one expansion turbine operatively associated with said compressor and constructed and arranged to operate above the full rated power of the combustion turbine assembly, and at least one combustor feeding said at least one expansion turbine; the system including a generator coupled with one of said at least one expansion turbine and said at least one compressor, the generator having a capacity to provide electric power exceeding the full rated power of the combustion turbine assembly; flow path structure fluidly connecting an outlet of said at least one compressor to an inlet of said at least one combustor; a supplemental compressor structure configured to provide maximum supplemental compressed air which is a fraction of maximum compressed air provided by the at least one compressor of the combustion turbine assembly; connection structure fluidly connecting an outlet of said supplemental compressor structure to a point upstream of said at least one combustor; and valve structure associated with said connection structure to control flow through said connection structure, the method including:selectively controlling the overall system and said valve structure to selectively permit one of the following modes of operation:a combustion turbine mode of operation by closing the valve structure, wherein air compressed by said compressor moves through said flow path structure to said combustor feeding said expansion turbine such that said expansion turbine drives said generator and said at least compressor, andwhen power higher than the full rated power of the combustion turbine assembly is required, an intermittent electrical power augmentation mode of operation by at least partially opening the valve structure, wherein supplemental compressed air from said supplemental compressor structure is supplied through said connection structure and is directed to said at least one combustor feeding said at least one expansion turbine, in addition to compressed air passing through said flow path structure to said at least one combustor feeding said at least one expansion turbine, which increases mass flow of compressed air and gas to said at least one expansion turbine to generate electric power exceeding the full rated power of the combustion turbine assembly while maintaining a constant frequency of the combustion turbine assembly.
