Resumo: | |||||||||||||
The oil and gas industry accounts for a considerable portion of Brazil s GDP and can therefore be considered as one of the pillars of the country s econ-omy. As almost all of this resource, even more so after the discovery of the pre-salt, is in the deep seas or in places of difficult access, there is a need for a source of electric energy to execute the activities of exploration and production of the oil. The most common solution found for this problem is the electric power generation through a gas turbines. The gas turbine is a rotary thermal machine capable of converting kinetic and chemical energy into work in the form of rotation of an axis, which when coupled to a gener-ator, converts this work into electrical energy. Not all power supplied to the machine, however, is converted into useful work because of a number of factors (such as: irreversibility in thermodynamic processes, losses in form of heat, poor condition of turbine components, etc.). The present work seeks to model the actual thermodynamic cycle of a gas turbine, identifying the points of loss of that energy for different configurations of a gas turbine, as well as in operation with varied fuels and different GT loads. The results obtained were confirmed with the experimental data for a discrepancy of less than 0.05 percent.
