A thermodynamic simulation of the power generation gas turbine of the
Mosul gas turbine power station was carried out, and its performance was
observed. The simulation included detailed modeling of the compressor, the
combustion chamber and the turbine based on the physics as well as the common
practice in the field. Comparison of the simulation code results with the field
collected data indicated agreement to within 2% of the compared parameters. The
developed code then used to study the effect of varying the ambient temperature
on the performance of the system. The results showed a decrease of up to 21% in
the power output when the ambient temperature increases from its ISO value of
15 °C to 45 °C. Comparison between running the system under constant turbine
inlet temperature and constant turbine power output were also conducted.
