Robust Economic Model Predictive Control for Variable Speed Variable Pitch wind turbines

第三十九届中国控制会议

作者： Na JIANG Ning LI Key Laboratory of system Control and Information Processing Ministry of Education of ChinaShanghai Jiao Tong University

With the development of intelligent monitoring technology, internet information technology, and data storage technology, data-driven fault detection and diagnosis method in the wind turbine system has become a focus of research in recent years. In this paper, we design a data-driven architecture for the wind turbine frequent principal fault detection. Considering the sequential relationship in the wind power data, we introduce the long short-term memory（LSTM） model. Additionally,to retain more necessary information hidden in the wind power time series, which is too long to make the performance of the LSTM model poor, we propose a novel self-attentive LSTM encoder-decoder（SALSTMED） model to learn the high-level feature sequence other than the feature vector. Further, the dataset collected from a real wind farm is employed to verify the performance of the proposed approach. The results indicate that the proposed approach is effective for the wind turbine frequent principal fault detection.
