The development of performance prediction is one of the most important aspects of the design of wind turbines. In this paper, a developed methodology is used to predict the optimal performance of the horizontal axis wind turbine in terms of the most critical parameters such as tip speed ratio, pitch angle, blade number and wind speed. Interesting generalized performance maps were conducted. Results show that low pitch is recommended for low wind speed regime. A range of (5 to 11) of tip speed ratio is found an optimum within the constraints considered. The interplay of cut in speed with the remaining parameters is also studied and their effect on power and torque are explored. Several results were presented for a three bladed wind turbine is it is preferred by many manufacturers and researchers.
