Description
Technical field：
The present invention relates to wind power generation field, a kind of deep-sea suspended wind power generating set is more particularly to.
Background technology：
As the continuous progress of modernized society, national economy are continued to develop, the problem of being brought by energy crisis day
It is beneficial serious.In face of the increasingly serious of energy crisis, each state in the whole world replaces traditional energy all finding the new energy energetically, with
Wind energy, solar energy, biomass energy, ocean energy etc. have become the important goal of current energy development for the new energy of representative, special
It is not that wind-power electricity generation and solar energy generation technology have reached its maturity and used in current electric energy and occupied important proportion.
The wind-power electricity generation of China starts development in 1980s, surmounts U.S. from 2010 Nian Qi China wind-powered electricity generation generating total amounts
State keeps the ranking in the whole world first.On the basis of internal land wind electricity builds centralized large-scale development gradually saturation, although simultaneously
Net is difficult, off-grid accident still has generation, and China's Wind Power Generation Industry has begun to turn to heavy amount, exploitation distributing and offshore wind farm
Type.Offshore wind farm can be divided into the depth of water of the classification of offshore wind farm generally according to exploitation place according to the distance of its water front off sea, can
To be divided into four kinds of beach, intertidal zone, Offshore and deep-sea.Because offshore wind farm is in different depth of water environment, therefore need
Otherwise with foundation structure support blower fan, deep-sea type blower fan typically uses float type structure, i.e., install wind-driven generator
On a raft, raft is fixed with seabed by cable.Current Norwegian National oil Hai Deluo companies
（StatoilHydro）The North Sea of the first floating marine formula wind power station in the world of construction near Norwegian coast is formally enabled,
This wind-driven generator is entitled " Hywind ", high 65 meters, weighs 5300 tons, positioned at Norway west and south near shore Ka Moyi islands
（Karmoey）10 kms；Hywind generators are arranged on a floating platform, and floating platform is fixed by three cables with seabed.
For Floating deep-sea Wind turbines, it, which has, installs simple, is easy to migrate and manufactures, installation cost is than marine
Tower-type Wind turbines are low, and the wind energy at deep-sea is huge and stablizes, and will not typically take the space required for people's daily life.
But the wind scale of sea wind compared to land wind scale it is much bigger, due to deep-sea wind power generating set be it is floated installation and,
Therefore sea wind and wave can all cause rocking for Wind turbines（The vibration of low frequency）, this lasting rocks in influence wind turbine power generation
Damage can be also caused on the basis of efficiency and quality to blower fan structure.Therefore, how to suppress such vibration and just seem particularly heavy
Want.
The main generation under wind load and the effect of wave load of the structural vibration of deep-sea suspended wind power generating set, pin
To fixed deep-sea suspension blower fan structure, its caused vibration mode is relatively stable, in consideration of it, present invention proposition is a kind of new
