Disclosed in the present application are a blade fault diagnosis method, apparatus and system, and a storage medium. The method comprises: obtaining a blade rotation audio acquired by an audio acquisition device in an operation process of a wind turbine; preprocessing the blade rotation audio on the basis of a wind noise filtering algorithm to obtain a blade rotation audio subjected to wind noise filtering; splitting the blade rotation audio subjected to wind noise filtering, to obtain an audio clip corresponding to each blade; and diagnosing, according to each audio clip, whether the blade corresponding to each audio clip is faulty. According to the present application, on the basis of the audio clips of different blades, whether the corresponding blades are faulty can be respectively diagnosed, thereby improving the accuracy of diagnosis results.
