Abstract This project focuses on a design of a do-<br/>mestic wind turbine system for the Sub-<br/>Saharan Africa, as a suggestion to improve<br/>the present electrication rate. Theory<br/>concerning wind energy, wind rotors and<br/>induction machines are studied, in order to<br/>make a steady state model. A experimen-<br/>tal setup provided by Aalborg University,<br/>consisting of an induction machine (IM)<br/>used as generator, and a synchronous ma-<br/>chine, used to simulate a wind rotor, are<br/>used to verify the model of the wind tur-<br/>bine system. The model of the IM is ver-<br/>ied by experimental work, and it is ap-<br/>proved that, within the electrically rated<br/>range of the IM, the model is approxi-<br/>mately satisfying. To control the output<br/>power of the IM, the method of exter-<br/>nally modifying the rotor-resistance and<br/>the principle of pitching is reviewed. Dif-<br/>ferent wind rotor areas and gearbox ratios<br/>are examined, in order to nd a optimal<br/>wind rotor design for the complete wind<br/>turbine system with use of a wind distri-<br/>bution of Borris year 2009, Denmark. An<br/>optimal wind rotor design in chosen and<br/>it is concluded that the model can be a<br/>suggestion for improving the electrication<br/>rate of Sub-Saharan Africa.
