Abstract:To address complex fault risk for wind turbine pitch systems working under the long-term operation and harsh environment, a fault prediction method based on Swarm Optimization (SO) algorithm and optimized Support Vector Machine (SVM) is proposed. Firstly, principal component analysis (PCA) is adopted to identify the core feature values from a datasets of wind turbine variable pitch systems containing operating data and feature extraction. Secondly, an Improved Swarm Optimization (ISO) algorithm is introduced t… Show more
