Study the Possibility of Application of Wind Turbine under the Climatic Conditions of Iraq

Abstract

the article presents a mathematical model of small scale power wind turbine implemented in the MATLAB/Simulink software under the climatic conditions of Iraq. The study was conducted on the average daily, monthly and annual wind speed for most of the meteorological stations in the northern, central and southern regions of Iraq recorded at an altitude of 10 m. The results showed that the wind speed increases as we head south, especially in the central and southern region. In the paper has been calculated the coefficient of power and torque. A simulation model of wind turbine has been compiled for various values of wind speed from (5) to (13) m/s, and the angle of attack is zero. The mechanical and aerodynamic specifications of a wind turbine type Energiewind2 (2 kW) were studied. The ideal theoretical power coefficient (C <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">P</inf> ) for this turbine is (0.48), which shows that the efficiency of the turbine is the highest possible, that been to get the optimal tip speed ratio is (5.85). Finally, The mechanical power of the wind turbine that obtained (500-1500 Watts).
