Influence of Operating Conditions on the Performance Parameters of Gas Turbine Cycle Power Plant

الملخص

The focus of this study focuses on the possibility of operating and working
the gas turbine power plant under different operating conditions, to obtain a
high power output according to climatic conditions and design values. Where,
the geographical location and climatic conditions play a major role in
improving the performance of gas stations, thermal efficiency, specific fuel
consumption, and production capacity. As well as the geometrical design, the
internal structure of the material which is involved under the study of
materials science which came up with special alloys that can withstand high
temperatures. In this paper, an analytical study is presented on the effect of
operating conditions and ambient air temperature on the cycle performance of
a gas turbine plant. The study includes a thermodynamic model for the cycle,
considering the effect of ambient temperature based on the first law of
thermodynamics. Where results were obtained using a mathematical model
developed utilizing the programming language Fortran 90 on the basis of a
presentation presented in the form of graphs and patterns showing the
variation of performance parameters such as thermal efficiency, specific fuel
consumption, compressor work and specific work output under different
operating conditions like the compression ratio , turbine inlet
temperature(TIT), ambient temperature and isotropic efficiency of the
compressor and the turbine. It can be observed from the results that the best
thermal efficiency was obtained at the highest operating conditions for the
compression ratio and turbine inlet temperature with a lower temperature for
the compressor inlet, as well as for the lowest specific fuel consumption rate
that can be obtained under the same these conditions. As for the specific work
output, it is in the best conditions at a compression ratio of 15 under certain
operating conditions, taking into account the isotropic efficiency of the
compressor and the turbine. Also, lower temperatures at turbine inlet and
higher temperatures at compressor inlet have the influence on the specific
consumption rate of fuel. This is significantly of great importance in terms of
the economies of power plants
