Embodiment Construction
[0067] In the various figures of the application, structurally identical or functionally similar features are indicated by the same reference numerals.
[0068] First of all, the following description of the invention is mainly aimed at offshore wind power installations or wind farms. However, it should be clear to those skilled in the art that similar techniques can be applied to other water power plants such as lakes.
[0069] Figure 1A It shows a floating wind farm composed of 36 traditional floating wind power generation equipment, in which each wind turbine has a stand-alone capacity of 5MW, so the total power generation is 6×6×5MW=180MW, while each adjacent wind turbine The distance between them is estimated to be 840m, and the length of the required underwater connection cable is at least (5×840m)×6×2=50.4km.
[0070] Figure 1B Shown is a semi-submersible raft wind farm according to the present invention, which is composed of 12 semi-submersible raft wind power gene...

The invention relates to semi-submersible raft type overwater wind power generation equipment turning along with wind, in particular to offshore wind power generation equipment. The semi-submersible raft type overwater wind power generation equipment comprises a semi-submersible raft, at least three wind power generators and cables; the semi-submersible raft is composed of at least three buoys and connecting beams, the wind power generators are borne on the buoys of the semi-submersible raft, and the semi-submersible raft can be rotationally anchored to the water bottom through the cables. In the projection direction, the mass center where a resultant force action line passes when the equipment bears wind action in the horizontal direction does not coincide with the rotation center of the equipment, and therefore when the resultant force action line does not pass through the centroid and the rotation center simultaneously, the moment of force making the semi-submersible raft rotate around the rotation center so as to guarantee that the resultant force action line passes through the mass center and the rotation center simultaneously can be generated all the time. The invention further relates to a wind power generation plant with the wind power generation equipment and a construction method for the wind power generation equipment.
Description
technical field [0001] The present invention relates to a semi-submersible raft wind-turning surface or sea wind power generation equipment, and also relates to a water or sea wind power farm composed of such wind power generation equipment. The invention also relates to a method of manufacturing and constructing such wind power generating equipment. Background technique [0002] As an inexhaustible green energy, wind energy is being paid more and more attention at present. In addition to land wind power generation, water or offshore wind power generation has attracted more attention due to its advantage of not being restricted by geographical location. [0003] As nearshore wind farms will cause nuisance to nearby residents, it has become a trend for offshore wind farms to develop from nearshore to open sea. The open sea has a wide space, strong and stable wind, far away from the coast and invisible on the shore. Residents have little objection. [0004] Offshore wind fa...
