Dynamic Evaluation of Wind Turbine Health Condition Based on Multi-Source Information Fusion

Due to highly complex and non-stationary operation condition, a dynamic wind turbine health condition evaluation approach based on multi-source information fusion is recommended. The uncertainty and incompletion of evaluation factors are fully considered, both qualitative and quantitative evidences are integrated. A case study is provided to illustrate the implementation process of the dynamic evaluation approach for wind turbine health condition. It is shown that the proposed approach offers a flexible and effective way of wind turbine health condition evaluation and the result can be used as a support for condition based maintenance decision.
