In this paper the problem of model-based icing detection for wind turbines is considered. Based on a robust observer of the rotor angular speed, the increase of inertia and aerodynamic torque due to icing can be detected. Moreover, incorporating an online approximator, the amount of icing can be also estimated. Such estimation can be used to define a threshold with an associated logic to stop the turbine when the icing appears to be too severe. © 2016 EUCA.

Abstract
In this paper the problem of model-based icing detection for wind turbines is considered. Based on a robust observer of the rotor angular speed, the increase of inertia and aerodynamic torque due to icing can be detected. Moreover, incorporating an online approximator, the amount of icing can be also estimated. Such estimation can be used to define a threshold with an associated logic to stop the turbine when the icing appears to be too severe. © 2016 EUCA.File in questo prodotto:
