Abstract
The development of simple gas power plants is attracting significant interest. In this regard, the possibility of developing a simple gas power plant with a capacity of (125MW) is being discussed. The first stage represents the utilizing of the thermal energy carried by the exhaust gases coming out of the simple gas turbine unit, by combining the gas turbine unit with a steam turbine unit through a dual-heat recovery steam generator, to form the combined cycle gas turbine unit. As for the second stage, it is represented by capitalizing on the solar energy through integrating the latter with the solar energy field, to form the integrated solar combined cycle unit. The results show that the advantages obtained from the first stage are high power output, thermal efficiency and, best specific fuel consumption, which can be obtained at (185.423MW), (49.77%) and (0.147kg/kW.hr) respectively. Regarding the second phase, the results show that adding a solar collector contributed to increasing the amount of steam entering the steam unit. As a result, the power output and thermal efficiency of the combined cycle unit increased to (207.964MW) and (55.3%), respectively. As for the specific fuel consumption, it reached (0.1315kg/kW.hr).
