Problems solved by technology

The blades in the operation of the wind farm are early products. Recently, it has been found that the actual wind level of the wind farm is higher than the original design value of the blade. After investigation, the actual madness of the wind farm will be different every year, and some years do exceed the wind energy measurement and evaluation. value, which poses a threat to the normal operation of the blade

Abstract

The invention discloses a blade preventive enhancement method based on wind power environment change. According to the method, when actual extreme wind power is larger than originally designed wind power, local supplementary distribution is conducted on the PS side rear edge of a blade to conduct preventive enhancement. Aiming at a wind field reinforced blade with large annual wind speed change soas to ensure the operation safety of the blade, the method only reinforces the interior of the PS side, has no influence on aerodynamic efficiency, does not generate adverse influence on wind wheel balance, belongs to preventive reinforcement, and the blade can be put into normal use after a reinforcing material is solidified.

Description

technical field [0001] The present invention relates to the field of wind farm operation, in particular to a preventive enhancement method for blades based on wind environment changes. Background technique [0002] In recent years, the environment of the wind field has been constantly changing, the reference standards have been constantly updated, and the design technology has also been continuously improved, resulting in higher requirements for blade design. The blades in the operation of the wind farm are early products. Recently, it has been found that the actual wind level of the wind farm is higher than the original design value of the blade. After investigation, the actual madness of the wind farm will be different every year, and some years do exceed the wind energy measurement and evaluation. value, which poses a threat to the normal operation of the blade. Contents of the invention [0003] The purpose of the present invention includes providing a preventive enha...
