Abstract：Wind power generation is one of the most mature technologies in renewable energy and has been widely applied in the worldwide scale, where high reliability and economy have been important requirements for wind energy conversion system(WECS). Hence, the strategies to improve reliability and economy of WECS have been an interesting area for researchers. In this paper, the current situation, fault features and maintenance difficulties of WECS are introduced, and one primary effective way to improve reliability and economy, namely condition monitoring and fault diagnosis (CMFD) approach, is applied to WECS. Moreover, the state of the art in CMFD of WECS is overviewed, focusing on the main failure components, such as generator, gearbox, blade, etc. Finally, in accordance with the current problems of the CMFD technology, some possible development trends of CMFD for WECS are discussed.
