The Methods of Condition Monitoring for Key Components of Wind Turbine

摘要

The paper analyzed on failure mechanism of key components (blades, gearboxes) of wind turbine. Then, that introduced the development about the methods of condition monitoring of the key components. It also described that in recent years the development of methods with location of fault, fault diagnosis and failure distribution respectively. According to the present problems of condition monitoring of wind turbine, the text summed up the problems in four aspects for the future: research of the fault mechanism and failure criterion, vibration signal processing and the method of feature extraction research, study on coupling of wind turbine system, development of on-line monitoring systems.
