Description

technical field [0001] The present invention relates to on-line monitoring and fault diagnosis technology, and more specifically, the present invention relates to an on-line monitoring and fault diagnosis system for flange bolts of a wind power generating set. Background technique [0002] With the rapid development of the wind power industry and the continuous expansion of the scale of wind turbine assembly machines, the incidence of accidents in the operation of wind turbines has also increased significantly, some of which are caused by the failure of flange bolts. The damage caused by the bolt failure of the wind turbine is very serious, and the result often leads to the failure of the important parts of the wind turbine, or even the overall overturning of the wind turbine. The occurrence of this kind of accident will cause serious injury to the maintenance staff in the wind turbine, and cause huge economic losses to the country and enterprises at the same time. By the e...
