 This research provides a comprehensive analysis of a 1.5 kW horizontal wind turbine with a rotor diameter of 1156mm. The turbine model was designed using Catia software, and its aerodynamic performance was analyzed using ANSYS/Fluent. Notably, our findings reveal that the power output of the turbine increases significantly with an increase in the angle of attack, peaking at 7.4 degrees. 

Further, the feasibility of the model was assessed to determine both the economic and environmental benefits of the proposed design. This assessment considered various factors, including cost-effectiveness, energy efficiency, and potential reductions in carbon emissions.

in addition, the study investigated the influence of blade pitch angle on the aerodynamic efficiency and overall turbine performance. Experimental observations and mathematical modelling demonstrated that the turbine power coefficient (Cp) decreases as the pitch angle deviates from the optimum operating condition. This behaviour was represented using an exponential decay relationship based on the squared deviation from the optimum pitch angle,where the pitch sensitivity coefficient was determined as k=-0.0025. This relationship enabled the development of a simplified mathematical model capable of predicting turbine performance under varying wind speed and pitch angle conditions.

For validation purposes, the design's effectiveness was tested using Simulink Matlab by measuring the output mechanical torque (Tm(pu)). This torque Tm(pu) is directly connected to electrical generator block in simulink which is linked to measuring bus selector. Impressively, the turbine's output power was found to be 98% similar to that obtained through experimental validation, underscoring the accuracy of our simulation models.

Overall, the integration of these sophisticated software tools and detailed experimental validation underscores the robustness and potential of this wind turbine design for practical applications, particularly in grid-connected settings. This study not only confirms the technical viability of the turbine but also its potential to contribute to sustainable energy solutions.
