Description
Technical field
The present invention relates to a kind of wind generating technology, particularly a kind of MW class wind turbine group blade and method for making that can photovoltaic generation.
Background technique
Solar energy is most important basic power source in the various renewable energy sourcess, and biomass energy, wind energy, ocean energy, water ability etc. are all from solar energy, and in a broad sense, solar energy comprises above various renewable energy sources.The solar energy amount of accumulateing is huge, can be described as inexhaustible, nexhaustible.
Solar energy is a kind of as renewable energy sources, then is meant the direct conversion and the utilization of solar energy.Convert solar radiant energy the solar energy utilization technique that belongs to of heat energy utilization to through conversion equipment, utilize the solar energy thermal-power-generating that is called that heat energy generates electricity again, also belong to this technical field; Belong to the solar energy generation technology to what solar radiant energy converted utilization of power to through conversion equipment, photoelectric conversion device normally utilizes the photovoltaic effect principle of semiconductor devices to carry out photoelectric conversion, therefore is called solar-photovoltaic technology again.Do not produce in the solar electrical energy generation process and pollute and noxious emission clean environment firendly.So solar electrical energy generation is the very desirable mode of current and expected future, can very well solve the permanent contradiction between the using energy source and ecological protection in the human development process.
At present, mostly China and larger in the world solar power plant are to utilize solar cell directly to convert solar radiation into electric energy, use, store or carry.Solar cell is mainly by single crystal silicon, polysilicon and mix the silion cell of boron, gallium, phosphorus, arsenic, and kind is various.In shape, it is flat mostly solar cell is, be installed on the specific support, purpose be can more effective raising solar cell the unit area generated energy.But most solar power plant's floor spaces is bigger, and once installation, the soil just can't carry out other uses more simultaneously.Single solar energy utilization makes land use capability low, and at night and rainy weather solar energy electric power can't be provided effectively, and this is the drawback of large-sized solar generating field.
Wind energy is one of secondary green energy resource of solar energy, and global wind energy content is abundant, has reached 20,000,000,000 kilowatts.Wind energy also is cleaning, free of contamination renewable resources, and in fossil energy deficient day by day today, the utilization of wind energy more and more receives the attention of countries in the world, and has obtained development rapidly and efficiently.By the end of the end of the year 2010, China wind-powered electricity generation accumulation installation total amount reaches 0.46 hundred million kilowatt, and present main flow wind power generating set is power megawatt rank, and the unit generated energy is big.
The wind power plant multidigit of China in the northwest, the Inner Mongol, the desert in northeast, Gobi desert, grassland, and coastal beach area, east and offshore area.This type area one is that wind resource is abundant, the 2nd, and comparison is spacious, and the sunlight resource is rich also.Be security consideration, wind power generating set unit floor space is bigger.If only utilize wind energy, energy utilization rate is just lower on the unit area soil; And run into weather calm or that wind is big, wind power generating set will be shut down, and can not generate electricity.
Consider that large-sized solar generating field and wind energy power field all can cause the shortcoming of equipment and idle land under specific weather conditions, the wind light mutual complementing comprehensive electric generating equipment of maximization obtains people's attention gradually.
MW class wind light mutual complementing power generation field in China does not also have relevant academic research paper and patent report, and many about the patent report of the power generating equipment of miniaturization.This type wind light mutual complementing power generation equipment is many to be realized through solar cell is installed on small-sized wind power generator top or column, is common in city illumination etc., can not solve the problem of large-scale wind field and solar energy electric field.
