Application of heterogeneous information fusion inmulti-criteria assessment of wind turbines
异构信息融合在风电设备状态多准则评价中的应用

Aimed at the problem that the information about wind turbines is distributed and heterogeneous in wind farms and the overall status of wind turbines are difficulty to evaluate, this paper presented an ontology-based multi-criteria assessment method to assess the healthy status of wind turbines. Based on the common ontology, it modeled the knowledge in various information sources and structured the communication mechanism of global query. The overall status of wind turbines could be got in the form of quantitative assessment results by using of multi-criteria assessment. The data maintaining cost was low and the interferences to the original maintenance systems was minimized. This method can integrate various forms of data in wind farms and provide supports to develop maintenance plans in enterprises.
