Abstract

Wind turbine blade icing poses significant risks to operational safety and energy production efficiency. To address this challenge

this study proposes an ice detection framework combining XGBoost feature selection with a Sparrow Search Algorithm （SSA）-optimized convolutional neural network （CNN）. First

XGBoost evaluates feature importance in SCADA system data to eliminate redundant variables

streamlining model architecture and accelerating diagnostic processes. A CNN then extracts discriminative features from this refined dataset to establish an ice accretion classification system. The SSA subsequently optimizes critical hyperparameters in the CNN model to enhance detection precision. Experimental validation demonstrates 98% diagnostic accuracy for blade icing conditions

outperforming both Long Short-Term Memory networks（97.2%） and k-Nearest Neighbors classifiers （95.1%）. This integrated approach provides a reliable solution for real-time ice monitoring in wind farms.
