ABSTRACT = {The blades of wind turbines located at high latitudes are often covered with ice in late autumn and winter, where
this affects their capacity for power generation as well as their safety. Accurately identifying the icing of the blades
of wind turbines in remote areas is thus important, and a general model is needed to this end. This paper proposes
a universal model based on a Deep Neural Network (DNN) that uses data from the Supervisory Control and Data
Acquisition (SCADA) system. Two datasets from SCADA are first preprocessed through undersampling, that is,
they are labeled, normalized, and balanced. The features of icing of the blades of a turbine identified in previous
studies are then used to extract training data from the training dataset. A middle feature is proposed to show how
a given feature is correlated with icing on the blade. Performance indicators for the model, including a reward
function, are also designed to assess its predictive accuracy. Finally, the most suitable model is used to predict
the testing data, and values of the reward function and the predictive accuracy of the model are calculated. The
proposed method can be used to relate continuously transferred features with a binary status of icing of the blades
of the turbine by using variables of the middle feature. The results here show that an integrated indicator system is
superior to a single indicator of accuracy when evaluating the prediction model.},
