The wind turbine generator can be effectively overhauled and maintained, and economic operation and safe operation of a power system are guaranteed.

Description

technical field [0001] The invention relates to the field of electric power technology, and in particular to a wind turbine maintenance method and device considering multi-attribute meteorological characteristics. Background technique [0002] In the context of the continuous advancement of the "dual carbon" strategy, the adjustment of my country's energy structure has accelerated, and wind turbines have gradually replaced traditional energy sources as the general trend. The report shows that by 2021, the installed capacity of wind turbines in my country will exceed 300 million kilowatts, and the installed capacity of new energy units represented by wind turbines will increase steadily. Compared with traditional hydrothermal power units, the operating environment of wind turbines is relatively harsh, and the units are more prone to failures, shutdowns, failures, etc., which seriously affect the continuous and stable operation of the entire system, and bring immeasurable econ...

AI Technical Summary

Problems solved by technology

[0005] 1) For troubleshooting, due to the need for rapid recovery of equipment, the elimination of faults during the maintenance process is often superficial, usually only by replacing wind turbine components, etc. The obvious disadvantage is that the fault elimination is not thorough and in-depth , resulting in low equipment operation efficiency and high possibility of failure again

[0006] 2) For condition-based maintenance, it is generally necessary to establish a corresponding life prediction model for different components of wind turbine equipment, which is highly dependent on monitoring equipment

The existing planned maintenance model of wind turbines ignores the particularity of the operating environment of wind turbines, and does not consider the influence of meteorological characteristics on the failure rate of wind turbines, which has certain limitations
