Description
Technical field
The present invention relates to generator, and in particular to a kind of double wind wheel Double-rotor wind-driven generator, refers to that one kind can be
The wind-driven generator that generating and generated energy are increased dramatically is realized under 6m -2m/s low wind speed gentle breeze environment.
Background technology
Wind energy is the most new energy of development potentiality in clean reproducible energy, and it is quite rich in the reserves of China
It is rich.
In recent years, China achieved tremendous development in terms of wind-powered electricity generation regenerative resource exploitation.It is well known that building
Generally there is problems with wind-powered electricity generation：1. chooses wind field, and wind speed will be in more than 10m/s（I.e. 5, more than 6 grades of wind）Could be effectively
Generate electricity, and China only has a small number of areas to reach this wind speed；2. it build outlying mountain area in, the transmission of electricity that networks needs remote set up more
Power network is conveyed, transmission losses is increased, and it is high to invest big cost；3. wind-powered electricity generations can not be used effectively, although the current wind-powered electricity generation of China
Generated energy less than the 4% of gross generation, but still abandon electric serious, abandon electricity and be even as high as 40 more than ℅.
These problems are solved, the method for existing use is：Develop middle-size and small-size, off-network distributed wind-power generator and locally disappear
Receive.As off-network distributed wind-power generator closer to power load, equipment is in low-voltage customer side, it is not necessary to long-range transmission ＆ distribution and enter
Net, is lost small.Nevertheless, simply practice effect is also extremely limited.Wind Power Generation Industry currently still suffers from three major issues：One is production
Industry unreasonable structure, undue to rely on " three Norths " base, distributing wind-powered electricity generation is still small and weak；Two be that wind power generation capacity accounts for whole generated energy
Ratio it is still relatively low, less than 4%；Three be to abandon electric situation still without effectively being solved.
Reason of searching to the bottom is that China overwhelming majority is low wind speed gentle breeze area, and wind speed is existing throughout the year in 6m-below 1m/s
Some wind generating technologies, very low in the rotating speed of this wind speed interval blower fan, generated energy very little even can not send out electricity.In order to improve
Generated energy, the technical scheme used at present is still to follow original technology path, exactly increases gear-box, increases gear ratio, is improved
Generator speed.But gear is fragile and is difficult to safeguard, energy transmission loss is also big, makes originally energy very low low wind speed hair
Electrical efficiency is lower, has further raised cost, and economic benefit is low, does not reach practical function, it is impossible to penetration and promotion.
In low wind speed generating this respect, if big technological break-through can not be realized from structural principle, it is impossible to be substantially improved low
The utilization of wind speed wind energy and generating efficiency, distributed off-network wind-powered electricity generation are difficult to be developed, and cannot produce more cleanings can
The renewable sources of energy.
