دراسة تأثير زاوية ميل الشفرات (β) على منحنيات الأداء الميكانيكي للعنفة الريحية من خلال المحاكاة الحاسوبية باستخدام (Matlab)

Abstract

This study presents a computer modeling and simulation to investigate the effect of the blade pitch angle (β) on the performance of wind turbine systems using Matlab/Simulink. The most important mechanical performance outcomes of the wind turbine were studied, namely the coefficient of performance (Cp), output power, and rotor torque. The simulation results demonstrated a close relationship between β values ​​and the wind turbine performance parameters. The most important results of the computer simulations indicate that increasing the blade pitch angle leads to a decrease in the power coefficient, especially at higher wind speeds. Furthermore, both the output power and mechanical torque decrease with increasing blade pitch angle. In general, the maximum power output of a wind turbine is achieved at specific values ​​of wind speed and (λ), which correspond to a specific rotational speed of the turbine rotor and a maximum performance coefficient (Cp).
