Description
Technical field
The present invention relates to a kind of wind energy conversion system equipment, more particularly, the present invention relates to be used in a kind of wind power plant the wind energy conversion system of wind collecting.
Background technique
In the historical background of oil crisis, various new energy technologies are by extensive exploitation and utilization.The new energy of current utilization mainly contain solar energy, nuclear energy, air ability, underground heat, morning and evening tides etc.
Wherein, wind energy more and more receives the attention of countries in the world as a kind of novel energy of clean environment firendly.The wind-power electricity generation industry development of China was later, but development speed was set up first wind energy turbine set very rapidly from 1986, and the national wind-powered electricity generation electric motor power in the end of the year 2000 has been increased to 344MW.New energy development plan in the middle of research according to resource situation, regional development situation and Infrastructure situation, is planned the year two thousand twenty, and China's wind-powered electricity generation electric motor power surpasses 1.5 hundred million kW.And according to being bound on the present developing state above 1.5 hundred million kW.Because wind power plant compares with traditional thermoelectricity, wind-powered electricity generation power generating equipment, develop comparatively slow, thereby the vigorously supporting of the development need national policy of wind-powered electricity generation.The anxiety of supplying along with the increase and the petroleum-based energy of environmental emission reduction pressure in recent years, national government is also increasing to the supporting dynamics of wind-powered electricity generation development, and the object of policy support has also turned to the manufacturing of paying attention to helping domestic wind power equipment by the emphasis generating in past.
The wind energy conversion system that generally adopts is at present formed by radial blade is set on turning axle.The required stress that bears mainly is made up of two-part on these blades: the first is because of the effect of blast, and blade is pushed to the downstream direction of wind and is bent the active force that fractures; Its two, bear the turning effort power that the promotion because of wind-force produces, this active force is the needed power of pushing generator output electric energy.These two kinds of active forces all belong to crippling stress; For bearing crippling stress, wind energy conversion system needs enough construction material intensity, just because of this; The windmill that existing technology designed must have to cause very sturdy blade, thereby these blades all have to become ultra heavy parts.For supporting these heavy members, the parts around the windmill, such as rotating shaft and bearing, the base of supporting shaft all need have high intensity, thus have to do both massive shape.
The weight of windmill is not only the problem of a manufacture cost; The more important thing is that heavy windmill can produce powerful rotatory inertia when rotated; And the phenomenon that this rotatory inertia is taken place when rotating as gyro; Can hinder the sensing that windmill changes rotating shaft, thereby windmill is difficult to adjust at any time sensing to adapt to the variation of wind direction.As everyone knows, wind direction is to change at any time, if can not positive meet the flow direction aweather, windmill just can not obtain maximum wind energy, thereby can not get best Wind Power Utilization effect.
Summary of the invention
