Abstract：[Significance]Fault diagnosis technology is the key to ensure the operation efficiency of wind turbines and re-duce the operation and maintenance cost.As an important part of wind turbine,it is of great significance to understand its basic dynamic model for fault diagnosis.[Analysis]Through literature review,detailed fault diagnosis methods for key components of wind power drivetrain,namely the main bearing,gearbox,and generator bearing,were introduced.With more complex working conditions and harsher operating conditions,traditional fault diagnosis methods are limited,so the fault diagnosis of the wind power drivetrain under complex working conditions becomes more important.Combined with the development of fault diagno-sis of the wind power drivetrain under complex working conditions in the past five years,the current fault diagnosis methods of large-scale wind power drivetrain under complex working conditions were summarized in detail,and the main research and de-velopment directions of the wind power drivetrain fault diagnosis technology in the future were discussed.
