Research on on-line monitoring and fault diagnosis of wind turbine

With the continuous development of society and the increase of human demand for energy, wind energy as a kind of clean renewable energy, receives the increasing attention from all over the world. As the industry of wind power has developed rapidly in recent years, the global capacity is enlarged constantly, the structure of wind power generation is becoming more and more complicated, at the same time, the accident of wind turbines also occur frequently. Therefore, it is necessary to carry out the research on the wind turbines in the real-time online monitoring, found the failure of the unit earlier and maintenance in time, this can improve the reliability of wind turbines, which is of great significance to the study of the condition monitoring of wind turbine and maintenance costs and other issues.
