Abstract

In order to monitor the health status of wind turbine structure, reduce operation and maintenance costs, and avoid failures such as tower collapse and blade breakage, a condition monitoring approach for wind turbines is proposed. The proposed approach employs proper orthogonal decomposition （POD） to perform dimensionality reduction analysis on the finite element model. It reduces the computational costs to achieve the online monitoring goal. Finite element models are constructed and analyzed based on the actual conditions of the tower and blades, respectively. The tower is simplified as a beam for static analysis. uses POD is used to create a reduced-order model, and an experimental platform is established to validate the reduced-order model. The blade is simplified as a central rigid-flexible beam model. The transient response of the blade can be analyzed using the reduced order model. Comparative analysis and discussion of the results indicate that the proposed approach enables online monitoring of the health status of wind turbine structural components.
