Description
Technical field
The utility model relates to the technical fields of Oversea wind power generation, refer in particular to a kind of semi-submersible type offshore wind generating
Group basic platform.
Background technique
Coastal waters wind resource is abundant, the wind resource of blue water more horn of plenty than greater coasting area, and wind speed is higher, more
Stablize, economies of scale is more preferable.According to the research of the mechanisms such as Energy Research Institute, the National Development and Reform Commission, China far-reaching extra large 50
Offshore wind speed about 726.8GW at~70m, the depth of water are greater than 70m offshore wind speed about 524GW, are coastal waters more than 2 times, are land
Nearly 7 times of wind energy resources.Therefore, at sea, the general trend of events of offshore wind farm development is at deep-sea in the direction of the following Wind Power Development.
The advantage of floating blower is that floating concept can accommodate the wind power generating set of bigger single-machine capacity.With single machine
The increase of capacity, the design and construction that marine fixed basis is faced are challenged increasing, and floating blower sheet is as complying with
System realizes positioning by anchoring system under environmental condition effect, stronger to environmental suitability.Floating blower is deployed in far
Sea can acquire the wind-resources that turbulence intensity is smaller, wind speed is more stable.In addition the realization towage that floating structure can be convenient,
Either big parts for maintenance replacement is still towed back to from operating location to operating location and is carried out in towage, this realizes floating blower
Recycling and repetition deployment are possibly realized, while reducing offshore operations ship machinery requirement.
Compared with offshore oil and gas floating platform other than by wind, wave, stream environmental load, wind power generating set is still suffered from

And hybrid concept.Semi-submersible type basis, it is usually main to provide stabilization by moment of inertia of waterplane.Semi-submersible type is several floating relative to other
Formula blower pattern has smaller whole cost of investment, and shallower drinking water is so that its scope of application is wider and simple installation.
Reduction floating wind power foundation waves static amplitude and usually passes through increase platform hydrostatic restoring moment realization, hydrostatic
Restoring moment influence factor includes the displacement and GM (stability is high) on basis.It is to increase that GM value major way is improved on semi-submersible type basis
The water plane area of column, column is away from centre distance, and lower the center of gravity height, improves height of center of buoyancy.Increase displacement, increases floating
Basic steel using amount increases foundation cost.For semi-submersible type basis, increasing water plane area square is the effective way for improving GM
Diameter；And increase water plane area and GM, it can reduce that platform is vertical, rocks the natural period, make the natural period close to the main energy of wave
Range will increase its vertical and jigging motion response.Increase column and will increase support connection structure intensity requirement away from centre distance.
It adjusts load balance of plant blower to wave the corresponding mechanical, piping of torque needs increase using active and controls equipment, and
It needs to guarantee long-term running reliability, while increasing cost.
