Abstract:
This paper proposes a solution for ice accretion detection on wind turbine blades. The solution involves an
active deicing device that uses a conductive polymer paint to heat relevant surfaces of the blade under
electric potential difference. This deicing system is used here to perform a dynamic thermal characterization
of the blade for various operating conditions (with or without ice, with or without wind). The dynamical
behavior differences highlighted are then exploited using a dynamic observer to detect ice accretion through
the control signal produced by the observer. Tests carried out in a climatic chamber showed the validity and
the accuracy of the proposed method.
