Description
Technical field
The present invention relates to Offshore Wind Power Generation Technology field more particularly to a kind of offshore wind turbine suitable for blue water are new
Type buoyant foundation.
Background technique
The wind-powered electricity generation energy is a kind of reproducible clean energy resource.The offshore wind farm energy due to have do not take up an area, wind speed is high, operation
The advantages such as stable, start the extensive concern by national energy authorities and industry in recent years.Compared with the land wind-powered electricity generation energy,
With wind turbine power generation amount, high, single machine installed capacity is bigger, fan operation is more stable, wind power plant construction is not necessarily to for the offshore wind farm energy
The advantages such as land occupation.Practical experience shows remoter apart from coastline, and wind speed is bigger, and generated energy increase is more obvious.With between tide
The exploitation degree of band and greater coasting area wind power resources is gradually saturated and energy demand is stepped up, and Oversea wind power generation is between tide
It is inexorable trend that band and greater coasting area, which move towards blue water,.The resources reserve amount position of China deep-sea wind-powered electricity generation energy is at the forefront in the world,
The development prospect of offshore wind farm industry is wide.Compared with shallow sea wind power field, deep-sea wind power plant has wind speed height, wind shear low, rapid
Advantages, the influences to seaway such as process degree is small are also smaller.Therefore, deep-sea wind-power electricity generation is necessarily becoming for wind-powered electricity generation energy development
Gesture.
With the increase of the depth of water, conventional fixed-type offshore wind turbine foundation structure has been difficult to meet wanting for deep-sea wind energy development
Ask, and fixed offshore blower self weight and project cost increased considerably with the depth of water.Buoyant foundation structure is in abysmal area
The comprehensive cost in domain is far below the fixed foundation structure of blue water, and buoyant foundation structure mobility is good, quick detachable, is on active service
Expiring, which can be recycled, recycles.Therefore, in order to further develop the wind energy resources in deep-sea sea area, it is necessary to greatly develop buoyant foundation knot
Structure.Both at home and abroad still is in the research of offshore wind turbine buoyant foundation structure the elementary step at present, citation form mainly includes list
Column foundation structure, semi-submersible type foundation structure and tension leg type foundation structure.
Single column foundation structure is suitable for the higher offshore wind power system of center of gravity, eats since Area of Water Plan is smaller
Water is larger, and stability is generally preferable, and is conducive to improve the overall performance of deep water sea area floating blower, but single column base
The principal length of plinth structure is excessive, builds and installation is more difficult；Semi-submersible type foundation structure can be built on the coast, then towage is extremely
Designated place is connect with preparatory mounted anchoring system, and Attention problems are at low cost but cost of manufacture is high, semi-submersible type basis knot
The capacity of anti-storm of structure is strong, it is wide to be applicable in depth of water range, but stability is poor；Tension leg type foundation structure stability preferably, structure
It can build and assemble on the coast from heavy and light, generating set, but tension anchoring system construction is complicated, mounting process is complicated, installation fee
It is influenced with high, pretension by wind-force and wave environment.
Research institution of various countries and energy company are in theory analysis to the research of offshore wind turbine buoyant foundation structure at present
Or the stages such as model test, and China not yet starts to build deep-sea floating wind power facility.Therefore, wide in order to sufficiently develop China
Marine wind energy resource, build the wind power facility that can be run in blue water, need excellent in conjunction with various buoyant foundation structures
Point develops the novel buoyant foundation structural system of the optimal offshore wind turbine of performance.
Summary of the invention
The single column foundation structure of the comprehensive tradition of the present invention and the respective advantage and disadvantage of semi-submersible type foundation structure, propose a kind of tool
Have the dual anti-novel buoyant foundation structural system of offshore wind turbine for waving performance: the long column drinking water in center in structural system is deep,
