Exergy analysis of a power cycle system with 300 MW capacity

In this paper, the exergy analysis has been done to a power cycle system with 300 MW capacity. First, the calculation and analysis of exergy destruction and exergy efficiency are carried on for the specific working conditions on the basis of the calculation of thermodynamic parameters, and the comparison of the exergy destruction of the components is also conducted; then the analyses of variation features of exergy destruction and exergy efficiency are carried on with the ambient temperature changed, and the law of the impact that varied ambient temperatures do to the exergy efficiency of the system is reached.
