EVALUATION OF THE PERFORMANCE AND ENERGY EFFICIENCY OF INTEGRATED SOLAR COMBINED CYCLE POWER PLANT

Abstract

Abstract: An integrated solar combined cycle (ISCC) composed of a triple-pressure natural gas combined cycle and parabolic trough collector solar field is investigated in this paper. The purpose is to study and evaluate the performance of the cycle when the solar heat injected into the heat recovery steam generator of the steam cycle. Thus, a thermodynamic model of the proposed ISCC plant has been developed in Mathcad environment to simulate and analyze the cycle performance ate different seasons of the year. It has been found that the solar energy can generate steam that can be used to increase the power output of the steam cycle from 182 MWe to 237 MWe with an increase of 30% from reverence value. This can achieve an annual reduction in CO2 emission of 75000 tons/year.
