Abstract
A method is provided to ensure that a combustion turbine power generation system may operate at maximum allowable power at elevated ambient temperature and/or at low air density. The method includes providing 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 compressed air storage; a charging compressor for charging the air storage; charging structure fluidly connecting and outlet of the charging compressor with an inlet to the air storage; connection structure fluidly connecting an outlet of the air storage to an inlet of a saturator, a water heater to heat water directed to the saturator, a recuperator for receiving preheated and saturated compressed air, an outlet of the recuperator being in fluid communication with the combustor; and valve structure associated with the connection structure and the charging structure to control flow through the connection structure and the charging structure, respectively.
