Optimum Performance Improvements of the Combined Cycle Based on an Intercooler–Reheated Gas Turbine

The performance enhancements and modeling of the gas turbine (GT), together with the combined cycle gas turbine (CCGT) power plant, are described in this study. The thermal analysis has proposed intercooler–reheated-GT (IHGT) configuration of the CCGT system, as well as the development of a simulat...
