摘要： Provided in the present disclosure are a method and apparatus for evaluating the service life of a wind power generator set. The method comprises: acquiring historical data of a generator set; classifying historical operation data and other data in the historical data into corresponding operation state categories; determining a first proportion of each operation state category according to time information corresponding to the historical operation data; according to the historical data, determining an equivalent fatigue load corresponding to each operation state category; on the basis of the first proportion, superimposing the equivalent fatigue load corresponding to each operation state category, so as to obtain an equivalent fatigue load of the generator set; and determining the consumed service life of the generator set according to the equivalent fatigue load of the generator set.
