A General Overview of Combined Cycle Gas Turbine Plants

The Combined Cycle Gas Turbines (CCGT) has encountered a large diffusion over the last decades. Different researchers have focused on performance evaluation of CCGT through mathematical modeling techniques. Hence, there are some important factors which should be respected while modeling the CCGT. These factors include type of different components of the CCGT system, their configuration, the modeling methods, and the purpose of the modeling, the type and structure of the control system and the simulation objectives. Hence, a brief overview about CCGT design and technologies, mathematical modeling, simulation tools and methods are presented in this paper.
