Description
Technical field
The invention belongs to wind power generation field, is related to a kind of floating type offshore wind turbine base.
Background technology
Progressively exhausted new direction --- the offshore wind farm that the sight of the mankind has been transferred to clean energy resource of land wind-resources.
Offshore wind farm has the advantages such as wind speed is high, electricity is big, stable, suitable large-scale development, and offshore wind energy resource is most abundant
The southeastern coastal areas, adjoin the big developed area of power demand, it is possible to achieve electricity consumption digests nearby, reduce conveying into
This, development potentiality is huge.It is estimated that the energy benefits of offshore wind energy resource are higher by 20% to 40% than land wind-powered electricity generation.
It is more than 40 meters of deep water marine environment for the depth of water, the blower foundation economy of floatation type is more preferable.With offshore wind turbine
Immobilizing foundation compare, the advantage of floatation type blower foundation includes：
(a) limited by the depth of water it is small, wind field address choose it is more flexible；
(b) off-lying sea windward stock number is more sufficient, matter is higher；
(c) the Attention problems technique of blower fan, buoyant foundation and mooring anchor is simple, and most of construction can be completed at harbour；
(d) small, the portable height of shaping scheme is influenceed by seabed foundations condition；
(e) visual pollution of the off-lying sea elimination to coastal waters landscape can be arranged on.
At present, the ocean platform technology of petroleum industry is relied on, is primarily present three kinds of floating blower foundations：Single column
(Spar), tension leg type (Tension-Leg Platform, TLP), semisubmersible-type (Semi-Submersible).
Single column foundation structure is simple, but in order to provide enough restoring moment and stability, need to lower the center of gravity and larger eat
Water depth, sharp power is smaller outside vertical wave for it, has preferable heaving stability, but less water plane area can not contribute horizontal stroke
Shake and the stability of pitching both direction, the tilting moment of blower fan will reduce base fixed and fan efficiency.
The buoyant foundation of tension leg type has extraordinary heaving and rotates stability, but tension leg cost is high, installation is complicated,
Tidal fluctuations can also influence Tensity size in mooring leg, and the same frequency coupled vibrations of superstructure and tension leg system all causes this
Class system is difficult to design and construction.
Larger return can be but provided by the stable semi-submersible type multicolumn platform Area of Water Plan smaller (material province) of scattered cylinder
Multiple torque, on the premise of economy is ensured, platform stabilization is best.In addition, the construction and installation of the basis and blower fan can be
Harbour is completed, and towage to sea turn anchors fixed off field.
Analyzed based on more than, the floating blower concept design proposed in the world is a lot, but has built the floating of operation at present
Offshore wind turbine majority employs the steady formula partly latent basis of post, including the Windfloat by Principle Power companies and Japan
2MW Mirai and 7MW Shimpuu in Fukushima Forward projects.
As shown in figure 1, Windfloat is to design offshore floating type blower foundation product by Principle Power companies.
Portugal marine site that full-scale prototype is arranged on bank 5km off sea has been built within 2011, has been mounted with a 2MW blower fan thereon, has been tried
Generated energy after running 1 year is 3GWh.The platform is made up of the rod member of symmetrical three pillar type columns and connection, three pillar type columns
Bottom is provided with water squeezing plate, similar with column truss type platform.On a column, each pillar type column bottom is set assembling
Constant pressure water tank is used for reducing floating body center, improves stability.When incoming change of the wind, pass through the closed loop water of active control
Pump adjusts the heavy stability that can also improve system of water ballast of three floating drums, suppresses vibration.
Fukushima Forward project first stage (2011-2013) include building the 2MW post of semi-submersible type four drift
Floating blower fan.Fukushima Mirai (see Fig. 2) are designed using full steel structure, employ high-quality steel to improve platform anti-corrosion
Erosion and fatigue resistance, the 2MW fan rotor diameter 80m installed thereon, hub height are highly from water surface 65m, basic platform
32m, about 16m is absorbed water, using the steel mooring rope of 6 catenary suspension type continuous vulcanizations.It is cylinder to change four root posts in foundation structure, surrounding cylindrical
Bottom serves the effect of heave plate, bottom floating drum section is larger, there is provided buoyancy simultaneously lowers the center of gravity to external expansion.
Fukushima Forward projects second stage (2014-2015) includes building 7MW floatation type blower fan
Fukushima Shimpuu (see Fig. 3), are manufactured using steel, V-type three pillar type platform, column rectangular cross-section.
The design of offshore floating type blower foundation can not be carried out fully according to the oil gas Offshore Platform Design method of maturation.One
Aspect, the weight (700ton) of a 5MW blower fan are about the 1/10th even more small of general ocean platform superstructure weight,
Therefore dynamic response of the floating blower foundation under action of wave force will be bigger.On the other hand, the drilling well and oil transportation of ocean platform
Riser can not bear larger vertical deformation, therefore the suppression to heaving is most important, and wave the safety fortune to platform
Battalion influences smaller.Hydrodynamic characterisitic requirement of the offshore wind turbine to buoyant foundation platform is on the contrary, heaving is adopted for blower fan
It can influence less, only sufficiently small pitching and rolling free degree dynamic response just can guarantee that the high-efficiency operation of blower fan.
The content of the invention
In order to solve the wind energy on the sea Utilizing question of 40 meters of -200 meters of depth of waters, the invention provides a kind of three column semi-submersible types
Offshore wind turbine foundation, structure type is terse, and Path of Force Transfer is clear, high strength steel or cast-in-place high-strength concrete can be used to build
Make, be adapted to, more than sustainable current main flow 5MW rank blower fan assembled in bank shallow-water port Wharf Construction, ensure normally to make

Buoyant foundation includes three vertical columns being triangularly arranged in the present invention, and wind-driven generator is arranged on head tree
Top, the underwater bottom of head tree are connected with the column of periphery two times respectively by floating drum.With assembling in the four of geometric center
Column basis is compared, and the column semi-submersible type basis advantage of bias three of the invention and originality include：A) foundation structure is simpler,
Materials'use more saves, and cost is lower；B) the foundation structure characteristic size needed for the 5MW blower fans of current main flow, heaving week are directed to
Phase dramatically increases, and avoids the wave period of 17 seconds or so, and the limit for improving system deposits ability certainly；C) when assembling is three
When on a certain root post of spot footing, the asymmetry of structure will make the stability difference under different directions larger, but reasonably
Basic center of gravity is adjusted, setting angle is selected by wind meteorological data, basis can be made to provide bigger resistance to tipping moment；D) it is of the invention
A set of outside ballast regulating system of design, can continuously adjust structural focus, control blower fan in time in change of the wind
