1. A hybrid damping module configured to suppress vibration of a wind turbine, comprising a first damping unit, a second damping unit, and a connecting pipeline provided between the first damping unit and the second damping unit, wherein
the first damping unit is a permanent magnet eddy current damper comprising a rotor portion and a stator portion arranged in parallel with the rotor portion, the rotor portion is configured to be rotatable relative to the stator portion to generate electromagnetic damping, and a flow passage is embedded in at least one of the rotor portion and the stator portion; and
the second damping unit comprises a tuned liquid damper, the tuned liquid damper is in communication with the flow passage via the connecting pipeline to form a circulation loop, and a liquid in the tuned liquid damper is configured to circulate in the circulation loop, to directly cool the first damping unit.
