www.faa.govthe pitch control result in disproportionally large changes in induced drag and therefore changes in airspeed. As a result, pitch becomes a more effective control of airspeed when flying below L/D MAX and power is an effective control of the altitude profile (i.e., …

The strategies used to control the prime mover are generally similar. echanical M brakes and blade pitch control are commonly usedto avoid runaway conditionand keep the stresses on the mechanical s components of the wind turbine generator within the WTG operating range ofthe design tolerance.
