Thermodynamics Optimization of GARRI (1) Combined Cycle Power Plant by Using ASPEN HYSYS Simulation

Abstract

The study aims to simulate GARRI (1) combined cycle power plant by using ASPEN HYSYS. It aims to conduct a detailed thermodynamic analysis for combined cycle power plant and optimization to attend maximum efficiency by dissertating different scenarios of operating parameters. The study examined the operational side by passing through all the components of the combined cycle power plant and the mechanism of the system. Block 1 in GARRI (1) combined cycle power plant is used. The results efficiency obtained from ASPEN HYSYS simulator is 31.89%, while that of GARRI (1) is 27.4%. The effect of each operating parameter on the efficiency and power output was extracted by using Microsoft excel in form of graphical charts resulted from the thermodynamic analysis done by using ASPEN HYSYS simulator. The maximum efficiency in the optimum operating parameters is about 33.88% by using different scenarios
