Abstract

Embodiments of the present invention provide a fault warning method and device, which relate to the technical field of wind power generators. The fault early warning method is used for fault early warning of wind power generators, and the fault early warning method includes: obtaining various historical normal operation data and various historical fault operation data of wind power generators; Feature selection is performed on faulty operation data to obtain data features; model training is performed on data features to obtain a training model; real-time operating data of wind turbines are input into the training model to obtain early warning information. The fault early warning method realizes the fault early warning function of the wind power generator through various data of the wind power generator, thereby improving the accuracy of the early warning.

Description

technical field [0001] The present invention relates to the technical field of wind power generators, in particular to a fault early warning method and device. Background technique [0002] Most of the current fault early warning methods for wind turbines are based on data from one source to realize fault early warning for wind turbines.
