Abstract

Embodiments of the present invention provide a method and device for suppressing mechanical vibration of a wind power generating set and a wind power generating set. The method includes: acquiring the mechanical vibration condition of the wind generating set through a vibration sensor, the mechanical vibration condition of the wind generating set including the vibration frequency of the wind generating set; and controlling the output power of the wind generating set according to the mechanical vibration condition of the wind generating set Harmonic power is injected into the loop to make the wind power generating set generate active vibration, which is used to offset the mechanical vibration of the wind power generating set, wherein the frequency of the injected harmonic power is equal to the vibration frequency of the wind power generating set. Therefore, the purpose of reducing the overall vibration load of the wind power generating set can be achieved, and the service life of the wind power generating set can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wind power, and in particular to a method and device for suppressing mechanical vibration of a wind power generating set and a wind generating set. Background technique [0002] With the gradual depletion of energy sources such as coal and oil, human beings pay more and more attention to the utilization of renewable energy. As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. For coastal islands, grasslands, pastoral areas, mountainous and plateau areas that lack water, fuel, and inconvenient transportation, the use of wind power generation according to local conditions is very suitable and promising. Wind power generation refers to the use of wind turbines to convert the kinetic energy of wind into electrical energy. [0003] Wind turbines will generate vibration during operation. The vibration of wind turbines may...
