Abstract

The invention provides a hybrid damping module, a vibration suppression device, a vibration suppression method and a wind power generation set, the hybrid damping module comprises a first damping unitand a second damping unit, wherein the first damping unit comprises a rotor part and a stator part arranged in a form of being parallel to the rotor part, moreover, the rotor part is configured to beable to rotate relative to the stator part so as to generate electromagnetic damping, and a runner is formed in at least one of the rotor part and the stator part; the second damping unit comprises aliquid damper, the liquid damper is communicated with the runner and forms a circulation loop, and the liquid in the liquid damper can circularly flow in the circulation loop. According to the hybriddamping module provided by the invention, on one hand, a composite vibration suppression solution combined with TMD and TLD is provided, by combined usage of the TMD and the TLD, vibration suppression effect of the hybrid damping module can be improved, and on the other hand, a problem of damping force attenuation caused by temperature rise is solved for a permanent magnet eddy-current damping device.

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 itself rotates, etc.). [0003] The input of these excitation sources wil...
