Feasibility study of using industrial wind turbine in Manjil city by energy, exergy, economic and exergy destruction analysis

Abstract

The importance of producing clean energy without any pollutants, including carbon dioxide and nitrogen oxides, has increased due to climate changes caused by global warming. Wind turbine can produce clean energy. To use a wind turbine, the feasibility of using a wind turbine in that area should be checked. In this research, energy, exergy, economic as well as exergy destruction analyses were conducted for the feasibility of using the Nordex wind turbine in Manjiil city. According to the meteorological organization report, the number of winds in Manjiil city was obtained, and the average speed, average power, energy efficiency, exergy efficiency, exergy destruction and economic cost were calculated using existing equations. According to the outcomes of this research, the average power produced, energy efficiency and exergy destruction are high in the months with high average wind speed, and these months have lower exergy efficiency and economic cost. The cost of electricity generated in October is 0.0194 S/kWh, which is the lowest. The cost of electricity generated in December is 0.0292$/kWh, which is the highest. Also, the effects of cut speed, rated speed and failure speed on wind turbine performance were investigated. As the nominal speed increases, exergy destruction, production entropy and economic cost increase and energy efficiency and exergy efficiency decrease.
