Abstract—Combined Cycle Power Plant is the most effective among all the plants because in addition of high efficiency and power, it has other benefits such as fast Installation and flexibility. In this paper, Fars combined cycle power plant consists of gas and steam parts has been analyzed and optimized through technical and economical aspect with EES software. The evaluation criterion in the optimization operation is the objective function of total costs that includes the costs related to the current costs (thermodynamic sector) and investment costs (economic sector). In this method using of Exergy balance equations in the various components, value of Exergy flow in system lines and value of Exergy destruction in each component of the cycle is determined. In the next stage with balancing the cost of Exergy in each component of system, set of equations of Exergy cost has determined that with solving it, Exergy unit price in flow lines, Exergy destruction cost in different components of the system and other variables needing for analyze Exergy – Economic has obtained.
Index Terms—Component, combined cycle power plant, thermodynamic analysis, thermo economic optimization, exergy.
