In this work, a micro wind turbine will be designed and built for a series of wind tunnel tests (rotor dynamics and Wind Turbine (WT) start-up velocity). Its design stems from an original numerical code, developed by the authors, based on the Blade Element Momentum (BEM) Theory. From classic design criteria, having evaluated all the geometric characteristics, an innovative methodology will be shown for controlling the power curve of the wind turbine. Indications will be supplied in order to modify various sections of the power curve and so as to design the turbine according to its practical application. (C) 2009 Elsevier Ltd. All rights reserved.
