Abstract

The invention provides a hybrid damping module, a vibration suppressing device, a vibration suppressing method, and a wind power generating set. The hybrid damping module includes: a first damping unit, the first damping unit includes a rotor part and a stator part arranged in parallel with the rotor part, and the rotor The part is configured to be able to rotate relative to the stator part to generate electromagnetic damping, and a flow channel is formed in at least one of the rotor part and the stator part; a second damping unit, the second damping unit includes a liquid damper, and the liquid damper is connected to the flow channel. The channels communicate with each other and form a circulation loop, and the liquid in the liquid damper can circulate in the circulation loop. According to the hybrid damping module of the present invention, on the one hand, a composite vibration suppression solution combining TMD and TLD is proposed. The combined use of TMD and TLD can improve the vibration suppression effect of the hybrid damping module. On the other hand, it solves the problem of permanent magnet The problem of damping force attenuation of eddy current damping device due to temperature rise.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a hybrid damping module for suppressing vibration, a vibration suppressing device, a vibration suppressing method and a wind power generating set. Background technique [0002] A wind turbine is a green energy device that converts wind energy into electrical energy, and it can be roughly divided into onshore wind turbines and offshore wind turbines. Whether it is an onshore wind turbine or an offshore wind turbine, the external environment of a wind turbine is complex and accompanied by uncertainties. These factors constitute various excitation sources corresponding to the operation of wind turbines, including external excitation sources (such as external uncertain wind loads, irregular wave loads, etc.) and self-excitation sources (such as the imbalance of the impeller itself , the impeller rotates by itself, etc.). [0003] The input of these excitation sources ...
