Aerodynamic Separability in Tip Speed Ratio and Separability in Wind Speed- a Comparison [PDF]
Journal of Physics: Conference Series, 2014 From extensive application over a number of years, it has been established that the nonlinear rotor aerodynamics of typical medium and large wind turbines exhibit an effectively global separability property. Two versions of the separability of aerodynamic torque for variable speed wind turbines are investigated here; the separated function, related to ...
