Problems solved by technology

[0008] However, using the method to repair a pair of cracks is affected by the chemical properties of the adhesive itself, and the repair effect is poor.
Use method 2 and method 3 to repair the cracks. Scars will be left after the blade is repaired, which will change the airfoil of the blade and affect the power generation efficiency

Abstract

The invention discloses a method for repairing the cracks of the blades of a wind turbine generator system. The method comprises following steps: detecting whether the blades of a wind turbine generator system have cracks or not; and repairing the cracks by a vacuum assisted resin infusion technology and a first sensor if the blades have cracks. The provided method has the advantages that the repairing effect is improved, after repairing, the blades do not have any crack, and the generation efficiency is not influenced.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a method for repairing blade cracks of a wind power generating set. Background technique [0002] The wind turbine includes a wind rotor and a generator, and the wind rotor is composed of blades, hubs, reinforcements, etc. The blade is one of the key components of the wind turbine, and its performance affects the reliable operation of the entire wind turbine. [0003] Because the blades are exposed as a whole, the working environment is harsh, and under the influence of factors such as sun exposure, wind and sand erosion, rain and snow soaking, and lightning strikes, cracks will appear on the blades, which will cause resistance, noise and whistle when the wind turbine is running. The power generation efficiency of wind turbines will cause accidents in severe cases. [0004] At present, when there are cracks in the blade, there are mainly the following ways to repa...
