Background technology
Begin to get under the background in large-scale development stage at world's offshore wind farm, prelude has also been drawn back in Chinese marine wind electric field construction.Wind-powered electricity generation aspect at sea, coastal sea, Eastern China can be developed wind energy resources and reach 7.5 hundred million kilowatts approximately, and not only resource potential is huge and the development and use market condition is good.Since 2008, China's offshore wind farm resource is maintained good growth momentum, and the offshore wind farm project investment constantly heats up, and the construction of Oversea wind power generation field advances in order.
On January 22nd, 2010, country's issue " offshore wind farm development & construction management Tentative Measures " indicates that National Energy Board begins to strengthen the management of offshore wind farm exploitation, has started first batch of offshore wind farm royalty right project simultaneously.
In 2009; With the developer of country headed by the five big electricity power groups work in coordination with the complete machine merchant in Liaoning, the coastal area layout of provinces and cities such as Hebei, Tianjin, Shandong, Jiangsu, Shanghai, Zhejiang, Fujian, Guangdong intertidal zone and coastal waters wind-powered electricity generation resource, develop coastal wind-powered electricity generation for next step and lay the foundation.2010, along with developing coastal wind-powered electricity generation resource paces, country accelerates, and the wind-resources project that enclose early stage has all had substantial progress now.
China still lacks the offshore wind farm construction experiences; Wind energy on the sea resource measurement and assessment and the production domesticization of offshore wind farm unit are at the early-stage; Through combining national science and technology research project, the offshore wind farm relevant technologies is carried out case study in recent years, the technical specification system that China's offshore wind farm is built is progressively improved development; Formation has the offshore wind farm unit design and fabrication technology of independent intellectual property right, for the large-scale development of Chinese offshore wind farm creates conditions.
Oversea wind power generation will be greatly developed in following 30 years; China plans in the local extensive construction waterborne wind power station about 30 miles apart from seashore; These power stations possibly built on the huge buoyancy aid, also possibly go deep under water 120 feet and build on the continental shelf.In view of building on the huge buoyancy aid in the power station, just need a kind ofly can float on the sea and visible floating used for wind power generation cable.
Chinese patent document CN2720579 provides a kind of " buoyant cable ", comprises some insulated lines of circular distribution, and insulated wire is provided with oversheath outward, and the outer surface of said oversheath is provided with floating body with interior optional position.Floating body itself has less proportion, thereby the proportion that can make whole cable can directly swim in waterborne less than water; When this cable is used for operation at sea; Though can swim in waterbornely, appearance is high-visible, also is convenient to safeguard; But the tensile strength of this cable, water resistance, decay resistance, flexibility and bending property are all poor, thereby are not suitable for offshore wind energy plant.
In sum, for satisfying the needs of Oversea wind power generation, be necessary very much to design a kind of high-performance wind-force cable of floating use at sea.
Summary of the invention
