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.
