Mechanical device for suppressing resonant vibration of large-scale wind generating set

Abstract

The invention relates to a device for suppressing the resonant vibration of a large-scale wind generating set, and particularly to a mechanical device used for suppressing the resonant vibration by changing the inherent frequency of a wind-driven generator by altering the mass distribution of the large-scale wind generating set. According to the mechanical device for suppressing the resonant vibration of the large-scale wind generating set, vibration data of the wind generating set can be collected in real time and a response is made accordingly in time; the rotating parts of blades do not need to be adjusted, and the wind energy utilization ratio is not reduced.

Description

technical field [0001] The invention belongs to the field of wind power generation, in particular to a device for suppressing the resonance of a large wind power generating set. Background technique [0002] With the improvement of people's living standards, people's demand for electric energy is also rising. Although it is convenient to rely on the consumption of fossil energy such as coal and oil to provide electricity, it will cause problems such as smog, acid rain, and solid burning garbage. In order to reduce damage to the environment and enable the sustainable development of human society, people pay more and more attention to clean energy such as solar energy, wind energy, and tidal energy. Large-scale wind turbines absorb the kinetic energy of high air flow through blades, which have the advantages of high power generation density, simple equipment maintenance, and long power generation time. [0003] Practice has proved that the rotation of the blades of the gener...
