The invention provides a vortex-induced vibration suppression device and method and an offshore wind generating set. The vortex-induced vibration suppression device is used for being installed on a fan foundation of the offshore wind generating set, the vortex-induced vibration suppression device comprises an outer rotating drum and a rotary supporting piece, the outer rotating drum sleeves the fan foundation, the rotary supporting piece is arranged between the outer rotating drum and the fan foundation, supports the outer rotating drum and allows the outer rotating drum to rotate around the fan foundation, and a plurality of vortex generators are arranged on the outer surface of the outer rotating drum. According to the vortex-induced vibration suppression device and method and the offshore wind generating set, the position of the vortex-induced vibration suppression device can be adjusted in a targeted mode according to incoming flow direction changes, and therefore the optimal effect of suppressing vortex-induced vibration is achieved.
Description
technical field [0001] The invention relates to a vortex-induced vibration suppressing device for a fan foundation of an offshore wind power generating set, an offshore wind generating set including the vortex-induced vibration suppressing device, and a vortex-induced vibration suppressing method for the offshore wind generating set. Background technique [0002] Due to the advantages of high wind speed, low wind shear, low turbulence, and high power generation hours in offshore wind farms, the installed capacity of offshore wind turbines has grown rapidly, and offshore wind turbines have become an important field for the development of wind power technology. [0003] The wind turbine foundations used for offshore wind turbines are divided into different forms such as single pile, multi-pile, gravity type, suction type, and floating type according to factors such as offshore distance and offshore environment. Among them, single-pile cylindrical foundations are widely used. H...
