Abstract:
Gas turbine is one of most widely used in power plants to generate electricity or mechanical power options in the industry , which is having its own advantages and disadvantages . if the turbine use simple , efficiency is generally below 33%. . After installing and employ , these turbines produce efficiency less than their nominal amount . The methods no change in structure exist that increase the efficiency or power of the turbine to acceptable level .In this thesis, gas turbine and to improvement performance methods has been studied . gas turbine with the methods are simulated to obtain the effect of each method in different environmental conditions . Economic sensitivity analysis is done to investigate the effect of parameters such as price of water and annual work hours .All methods have been employed in the optimization program in order to optimize Combinations of them to achieve goals such as maximum output power, maximum efficiency and maximum exhaust gas energy. The results show that the optimal combination of these methods can Increase gas turbine power about 50 percent and its efficiency to 20 percent
