Beschreibung
Zusammenfassung:	The invention relates to research on a fan preventive maintenance method, in particular to a fan preventive maintenance method based on equipment state diagnosis, which is applied by taking multi-source data extracted from each information management system of a fan as a basis, regarding sudden faults of a wind turbine generator in a wind power system as random variables and taking the random variables as random variables. A high-frequency signal is decomposed in a wavelet transform mode, extraction of sudden fault fluctuation signal features of the fan equipment is completed, and a fault prediction model of the fan equipment influenced by the meteorological environment based on a random forest algorithm is established through outlier sample diagnosis based on a WDOKOD clustering algorithm. And constructing a wind turbine generator equipment real-time state comprehensive evaluation model and a wind turbine generator maintenance model based on a state opportunity maintenance principle by combining the change o
