Parametric Study on a Horizontal Axis Wind Turbine Proposed for Water Pumping

Water pumping is considered an economically competitive sustainable process of providing water to communities, rural areas and livestock's. A parametric analysis on HAWT is carried out to explore the influence of the performance parameters on the power generated and withdrawal quantity of water. Effect of wind speed, radius of rotor, ambient condition, well depth, and efficiencies of turbine, generator and the pump were studied and reflected in important generalized performance maps. These performance graphs are valuable in best understanding of on-design and design constraints of the horizontal axis wind turbine in water pumping. The blade geometry was also studied. Results showed the reasonable range of wind turbine performance and the corresponding water discharge within the abovementioned constraints. Rating and the effect of pitch angle on discharged water are also presented. Methodology necessary to achieve the abovementioned results is processed by a computer program written in Matlab.
