Abstract
Gas/steam combined-cycle is a well-known technology for power generation due to its numerous advantages including high efficiency and low environmental emission. The purpose of this paper was investigation of thermodynamic parameters' behavior of single-pressure system due to load reduction of gas turbine. In this study, dynamic simulation is performed to analyze the transient behavior of a combined-cycle power plant. This simulation was done using mass and energy conservation equations for each component as a control volume. Governing equations set was solved by forward finite difference method and the results were illustrated by some figures. For validation of this transient modeling, the bottoming cycle parameters values at the end of transient operation were compared with the numerical output of the well-known commercial software Thermo flow in steady state mode that acceptable adaption have been seen.
