The goal of this dissertation is to allow, through a computational tool, the analysis of the potential of a water pumping system based on the values of wind speeds in one location, using a small wind turbine coupled to a centrifugal pump through a variable speed drive. In the work two methods for the calculation of the flow are presented. Method 1 uses a theoretical model, while in method 2 the modeling is done from pumping data obtained in laboratory. The two methods describe the operation of a water pumping system involving the above equipment. Using the mathematical models described, a program was developed in Delphi® to obtain the values for the flow and volume of pumped water, and the number of people that can be supplied on the basis of the data of wind speed for the site, in order to analyze the feasibility of the system. The operation of the program is described through an example, in order to facilitate its understanding, which contains real values of wind speed, and the results are analyzed.
