Abstract

The embodiment of the invention provides a fault early warning method and device, and relates to the technical field of wind driven generators. The fault early warning method is used for carrying outfault early warning on the wind driven generator. The fault early warning method comprises the steps that various historical normal operation data and various historical fault operation data of the wind driven generator are acquired; Performing feature selection on the plurality of historical normal operation data and the plurality of historical fault operation data to obtain data features; Performing model training on the data features to obtain a training model; And inputting the real-time operation data of the wind driven generator into the training model to obtain early warning information. According to the fault early warning method, the fault early warning function of the wind driven generator is achieved through various data of the wind driven generator, and then the early warning accuracy is improved.

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. Due to the single source of data, the accuracy of fault early warning for wind turbines is not high. Contents of the invention [0003] The purpose of the present invention is to provide a fault early warning method and device. 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. [0004] In order to achieve the above object, the technical solution adopted in the embodiment of the present invention is as follows: [0005] In the first aspect, an embodiment of the present invention provides ...
