1. A method for detecting a fault in a wind turbine, comprising:
acquiring characteristic data and actual temperature of a first wind turbine among n wind turbines, wherein the characteristic data of the first wind turbine is intended to characterize a working state of the first wind turbine, and n is an integer greater than 1;
acquiring a prediction temperature set including a plurality of predicted temperatures by inputting the characteristic data of the first wind turbine into a plurality of temperature prediction models, each temperature prediction model corresponding to one of the n wind turbines; and
detecting, based on the predicted temperature set and the actual temperature of the first wind turbine, whether the first wind turbine encounters a fault.
