ABSTRACT
This research work focus on the simulation of a gas turbine power plant using high pressure fogging air intake cooling system. Aspen HYSYS software was used for the simulation of the gas turbine with and without cooling system using the actual operating data for performance evaluation. The results obtained on the simulation of the gas turbine at ambient air temperature of 25.690Cwithout the use of cooling system showed that ambient air temperature decreases the net power output, thermal efficiency and increases the specific fuel consumption and heat rate. However, when the gas turbine was incorporated with air intake cooling system (high pressure fogging), there was drop in ambient air temperature which resulted to an increase in net power output, thermal efficiency and reduction in specific fuel consumption and heat rate.
