Description
Technical field
The present invention relates to wind energy plant technical field, specifically, it is to be related to a kind of leaf sail can the vertical shaft wind-force of folding send out
Power station.
Background technology
Wind-power electricity generation is that the kinetic energy kept watch switchs to electric energy.Wind-power electricity generation just forms one upsurge in the world, because wind-force
Generating electricity does not need to use fuel, also will not produce radiation or air pollution.
Wind energy, as a kind of regenerative resource of cleaning, is increasingly paid attention to by countries in the world.Its amount of accumulateing is huge, the whole world
Wind energy be about 2.74 × 10^9mw, wherein available wind energy be 2 × 10^7mw, more total than the water energy that can develop on the earth
Amount also wants big 10 times.According to estimates, only 1% surface wind just can meet the demand to the energy for the whole world, but at present to wind energy
Using requirement much cannot be met.
THE WIND ENERGY RESOURCES IN CHINA is enriched, the wind energy content that can develop about 1,000,000,000 kw, and wherein, land wind energy content is about
2.53 hundred million kw (land is liftoff 10m height material computation), marine can development and utilization wind energy content about 7.5 hundred million kw, altogether
1000000000 kw.
Wind is that do not have one of energy of public hazards.And it is inexhaustible.For hydropenia, short bunker and traffic
The offshore islands of inconvenience, Pastoral Areas, mountain area and plateau area, utilize wind-power electricity generation treatment in accordance with local conditions, are especially suitable for, having greatly can
For.Offshore wind farm is the key areas of Renewable Energy Development, is the important force promoting wind power technology progress and industrial upgrading,
It is the important measures promoting Energy restructuring.China's offshore wind energy resource enriches, and accelerates offshore wind farm project construction, for rush
Enter coastal area to administer atmospheric haze, readjust the energy structure and Economic Development Mode Conversion is significant.
