“…Jahangiri et al [78] developed exergy, thermo-dynamical and economic analyses based on the effect of a flue gas injection system. While Kilani et al [79] analyzed the effect of two applications of steam injection within the combustion chamber. They obtained that with an adequate steam injection process which can improve the overall cycle efficiency up to 60%.…”

The Combined Cycle Gas Turbines (CCGT) has encountered a large diffusion over the last decades. Different researchers have focused on performance evaluation of CCGT through mathematical modeling techniques. Hence, there are some important factors which should be respected while modeling the CCGT. These factors include type of different components of the CCGT system, their configuration, the modeling methods, and the purpose of the modeling, the type and structure of the control system and the simulation objectives. Hence, a brief overview about CCGT design and technologies, mathematical modeling, simulation tools and methods are presented in this paper.

“…Ganjehkaviri et al [26] have suggested that maintaining at 88% the steam quality at the turbine outlet station is a more realistic and feasible value for operating the ST in the CCPP at the optimum level. Kilani et al [27] made the comparison of CCPP in the two different structures in which the vapor in the fuel chamber is different In the first, the injected steam was produced in the HRSG, while the other was supplied using the HRSG placed at the outlet of the compressor. According to the results, the second project was more effective in increasing performance.…”

Natural gas combined cycle power plants (CCPPs) are widely used to meet peak loads in electric energy production. Continuous monitoring of the output electrical power of CCPPs is a requirement for power performance. In this study, the role of ambient temperature change having the greatest effect on electric production is investigated for a natural gas CCPP. The plant has generated electricity for fourteen years and setup at 240 MW in Aliağa, İzmir, Turkey. Depending on the seasonal temperature changes, the study data were obtained from each gas turbine (GT), steam turbine (ST) and combined cycle blocks (CCBs) in the ambient temperature range of 8-23°C. It has been found that decreases of the electric energy in the GTs because of the temperature increase and indirectly diminishes of the electricity production in the STs. As a result, the efficiency of each GT, ST and CCB reduced, although the quantity of fuel consumed by the controllers in the plant was decreased. As a result of this data, it has been recommended and applied that additional precautions have been taken for the power plant to bring the air entering the combustion chamber to ideal conditions and necessary air cooling systems have been installed.
