Abstract

The invention provides a fault self-test method and device for a wind power generator. The method includes acquiring operation data of the wind power generator after the wind power generator goes wrong; determining component information corresponding to the operation data by utilizing a preset data structure tree; determining fault information of a component with fault according to the operation data in the determined component information, wherein the fault information includes at least one among the following: fault number, fault cause and fault type. According to the invention, the component information can be determined through acquiring the operation data of the wind power generator and by utilizing the data structure tree, so that the fault number, the fault cause and the fault typeand the like of the component with fault can be determined according to the operation data; wind power generator fault detection difficulties are reduced effectively, time for troubleshooting for thewind power generator is reduced and wind power generator fault detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a fault self-detection method and device for a wind power generator. Background technique [0002] With the rapid development of science and technology, wind power generation technology is becoming more and more mature. For wind power generation equipment, due to the continuous change of equipment selection, there are various configurations of megawatt-level MW units, and the variety of configurations brings many problems to on-site maintenance personnel. On the same project site, there may be several units with different configurations, and units with different configurations may produce different types of failures. [0003] In the prior art, for units with different configurations, different types of failures may occur, so commissioning and maintenance personnel are required to have extremely high maintenance capabilities, and more energy is required to learn, thereby increa...
