Résumé: | Recently, combined-cycle power plant systems are the most
efficient concept used for generating electricity. The advanced closed
loop steam cooling system which involves the gas turbine and steam
turbine cycles has produced one of the most environmentally adequate
existing power generation systems. Gas turbines (GTs) were developed
quickly and used in many applications especially in combined cycle
power plants, due to their higher efficiency and lower emissions in
carbon dioxide (CO2), compared to other categories such as diesel
engines. Therefore, increasing attention in the study of heavy-duty gas
turbines (HDGT) models has been acquired with diverse amounts of
difficulty and merit. Thus, modeling and simulation of the HDGT
behavior under accurate operating conditions play a significant role
for efficient design as well as reliable manufacturing practice. Thus,
the improvements of their efficiency will significantly reduce (CO2)
emissions.This paper focuses on the impact of ambient temperature on
the gas turbine performance in the combined cycle power plant. The
study presents modeling and analysis of the gas turbine behavior based
on the frequency dependent model (FD model), using Matlab/Simulink.
In our approach, simple time delays are integrated to the FD model,
taking into consideration the effectiveness and accuracy of the model.
This is achieved by a complementary analysis study, of the temperature
effect on the efficiency of the gas turbine (GT), and then the combined
cycle power plant. |
