INFLUENCE OF OPERATION CONDITIONS ON PERFORMANCE OF COMBINED CYCLE GAS TURBINE

摘要：

Combined cycle gas turbine power plant is an advanced technology which produces power at high efficiencies.The first-law approach was used for the thermodynamic analysis of the combined cycle gas turbine power plant.The variations of operating conditions on the performance of the combined cycle gas turbine power plant were investigated.The programming of the performance model for combined cycle gas turbine power plant was developed utilizing the MATLAB software.The simulating results show that the overall efficiency increases with increase of the compression ratio, turbine inlet temperature and decreases the ambient temperature.The total power output increases with increase of the compression ratio, ambient temperature and turbine inlet temperature.The peak overall efficiency occurs at the higher compression ratio with low ambient temperature.The overall efficiencies for combined cycle gas turbine is higher (57％) compared to gas turbine plants.
