Abstract Ice accretion detection and anti-icing/deicing of wind turbines blades is the topic of this paper. A conductive polymer paint is used to heat relevant surfaces of the blade under electric potential difference. Based on a temperature measure provided by various sensors placed on the blade, a control system is designed to prevent the blade icing up during wind turbine operation or to deice the blade after a rest. This deicing start-up requires knowing whether or not ice is present on the blade. Thus an observer based ice accretion system is also proposed. Tests carried out in a climatic chamber showed the validity and the accuracy of the proposed solutions.
