Abstract
Based on condition monitoring technology and by using the error log of the Vestas wind turbine, a logic of a wind turbine maintenance is proposed and a query system of wind turbine error causality is set up in this study. The first step of the logic of wind turbine maintenance is to identify the class of the error code created from wind turbine. After classifying the error code, the Reaction and Acknowledge of wind turbine will be checked, and the descriptions of error including Signal, Module, and Parameter will be examined. According to these examinations, the fault cause of a wind turbine can be determined. The fault part can be determined by combining the fault cause and the functional classification of the wind turbine. A query system of the wind turbine error causality is set up by integrating the proposed maintenance logic of the wind turbine and the entity database of the wind turbine. Finally, the examples of the query system of the wind turbine are validated by the real maintenance cases provided by the Vestas wind farm of the Taipower company. The examples of the validation show that the query system of the wind turbine error causality is suitable and reliable.
