Fixed pitch wind turbine
WebThe wind turbine is assumed to be a fixed pitch variable speed machine with regulation applied by controlling the reaction torque of the generator. Full variable speed operation is assumed. A suitable operational strategy is described in Good-fellow and Smith [7] and is depicted in Figure 1 . Below rated windspeed the strategy is WebA wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases.

WebEquation 1 can be normalized. In the per unit (pu) system we have: where: A generic equation is used to model cp (λ,β). This equation, based on the modeling turbine characteristics of [1], is: with: The coefficients c1 to c6 are: c1 = 0.5176, c2 = 116, c3 = 0.4, c4 = 5, c5 = 21 and c6 = 0.0068.
WebThe power captured by the wind turbine is converted into electrical power by the induction generator and is transmitted to the grid by the stator winding. The pitch angle is controlled in order to limit the generator output power to its nominal value for high wind speeds. In order to generate power the induction generator speed must be slightly ...
