Abstract

The invention provides a blade mate-balance method, blades and a wind driven generator. The method is applied to the wind driven generator. The wind driven generator comprises the blades of different gravity torques, weights and gravity centers. Each blade comprises a blade root position counterweight point, a blade middle position counterweight point and a blade tip position counterweight point. The method specifically comprises the steps that with the blade of the highest gravity torque as the standard, the other blades are subjected to gravity torque mate-balance by adding balancing weights on the different position counterweight points of the other blades; and after the other blades are subjected to gravity torque mate-balance, with the blade of the highest weight as the standard, mate-balance is carried out on the weights and gravity centers of the other blades. In this way, the blade mate-balance method is flexible and diverse, and the technical problem that as the gravity centers of blades shift too much, the service life of an existing wind driven generator is short can be solved.

Description

technical field [0001] The invention relates to the field of blade trimming, in particular to a blade trimming and balancing method, a blade trimmed and balanced using the method, and a wind power generator including the blade. Background technique [0002] In the prior art, when the wind generator is inspected at the factory, it is necessary to balance the gravity moment of the blades of the wind turbine generator, that is, to balance the gravity moment deviation value between the blades of the wind turbine generator through the gravity moment balance. controlled within a reasonable range. The method of gravity moment balance is to adjust the gravity moment of different blades by adding counterweights at different positions of different blades. In the process of weight moment balance, the principle of minimum mass is often used for gravity moment balance. When using the principle of minimum mass for gravity moment balance, the position of balance is the weight point of the...
