As wind turbine rated power increase, the potential danger of the vibration is serious result of the rotor diameter and the hub height is longer and higher. Wind turbine vibrations will cause futile mechanical loads, such vibration loads maybe result to serious damage of wind turbine. In order to achieve vibration suppression, taking the uncertainty of turbulence which the operate environment of wind...
This paper, based on the reduced version of Beddoes-Leishman dynamic stall model, makes deeply research about airfoil dynamic stall for wind turbines. Considering about the operating environment of wind turbine, the model, constructed in this paper, neglects the compressibility of airflow, and mainly considers attached flow, trailing edge separation and vortex lift. This paper uses fourth-order Runge-Kutta...
The key of variable speed constant frequency wind turbine operating control is the rotor excitation control, This article state the double-fed generator stator magnetic field direction detection control principle, discussed the stator magnetic field localization and the rotor position definite method, The rotor excitation uses neural network PID control which realizes easily in DSP, and has developed...
