AB - A thermodynamic model is presented for evaluation of a solar hybrid gas-turbine
power plant. The model uses variable ambient temperature and estimates direct solar radiation
at different day times. The plant is evaluated in Barranquilla, Colombia, with a solar
concentration system and a combustion chamber that burns natural gas. The hybrid system
enables to maintain almost constant the power output throughout day. The model allows
optimizing the different plant parameters and evaluating maximum performance point. This
work presents pressure ratio ranges where the maximum values of overall efficiency, power
output, thermal engine efficiency and fuel conversion rate are found. The study is based on the
environmental conditions of Barranquilla, Colombia. The results obtained shows that optimum
pressure ratio range for power output and overall efficiency is between 6.4 and 8.3, when direct
solar radiation its maximum at noon. This thermodynamic analysis is necessary to design new
generations of solar thermal power plants.
