Description

A kind of solar tower photo-thermal and photovoltaic power generation apparatus and its electricity-generating method
Technical field
The present invention relates to-solar light-heat power-generation and solar energy-electric energy storage storing technology field, more particularly to it is a kind of too Positive tower photo-thermal and photovoltaic power generation apparatus.
Background technology
The whole world formally enters fossil energy and reduces, and the regenerative resource increased energy conversion epoch are decided, It is intended to adapt to such development trend from government, enterprise, social organization to ordinary people, 2016 when will be global new energy The first year in generation.
China is vast in territory, the solar illuminating time be divided into 5 classes area, year sunshine time it is longest be 3300 hours, Shortest is 1000 hours, wherein 2000 hours land areas account for about 2/3rds of national total area or more, China belongs to One of the country of solar energy resources rich reserves, the solar energy that China's top receives every year are about 14,700,000,000,000,000 kilowatt hours, It is equivalent to 4.9 trillion tons of standard coals.The application of solar energy is mainly solar water heater, photovoltaic battery panel power generation and photothermal reflectance Mirror optically focused power generation etc..
The principle of solar light-heat power-generation is by speculum and tracking system by solar light focusing to solar collector On, using the heat liquid or gas of the sun, liquid has water or oil.Gas has hydrogen, nitrogen, helium and air etc..Water is heated Electrical power generators are driven as steam drive steam turbine.Solar light-heat power-generation has slot type, tower, dish-style and linear luxuriant and rich with fragrance alunite at present Your formula etc. is several.
Existing slot type generation technology has been commercialized application in foreign countries, but power generation process needs largely to use water, and water is caused to provide The waste in source, tower technology is suitable with trough technology, is equally also required to great lot of water resources.Slot type and tower identical as thermal power station, Use steam turbine.Disc type solar energy power generation generally drives electrical power generators using Stirling engine.Stirling starts Machine is to push bent axle rotation to drive electrical power generators by piston using gas as working media, and dish-style manufacturing cost is very high, It is the 2 times or more of tank-type thermal power generation cost.Dish-style generated output is small, generally in 3~25kw or so.Currently without small-power steam Turbine, such as specification of 3~25kw.Linear Fresnel formula power generator, focusing ratio are less than 30, and slot type 70, tower is 1000, dish Formula is 6000, and focusing ratio is higher, and heating temperature is higher, and generating efficiency is more preferable.Engine is the bottleneck of photo-thermal power generation, is needed suitable The engine of interval generation is answered, technically to there is new breakthrough.
Slot type and tower-type electricity generation floor space are huge, and China's Coastal Areas is densely populated, and land resource is deficient, to ensure to plough Ground red line is firm, and land development slot type and tower can be provided without ground, can only arrive those western scarcely populated places and be selected Location, at present the western many cities in China all fermenting start photo-thermal slot type and tower-type electricity generation project.But western water shortage, photo-thermal power generation Be in embarrassing circumstances, the good area of illumination condition often lacks water resource, and the abundant coastal area of water resource but lack soil The power generation mode that ground is become reconciled.50 megawatts photo-thermal power generation year water consumption at 150,000 cubes or so, it is almost the same with thermal power station.The sun Energy photo-thermal power generation needs technological innovation to adapt to the power demand of China's Coastal Areas.
If external ordinary circumstance does not have heat accumulation, cost is 3~40,000 yuan/kilowatt, has heat accumulation to want higher, such as western class 7.5 hours heat accumulation slot type power stations of tooth, installation cost are 50,000 yuan/kilowatt, but have the power station power generation hourage of heat accumulation substantially Increase, not generally 1500~2000 hours of heat accumulation, heat accumulation 7.5 hours will be up to 3800~4300 hours or so, thus Generating efficiency also higher.In states such as Spain, the U.S., slot type power generation degree electricity cost is 20,000 yuan/kwh.If China realizes industry Change, at should be lower than them.After industry is formed, by domesticizing on a large scale, at should be lower than them.After industry is formed, By domesticizing, producing in batches on a large scale and technological improvement, it can accomplish 20,000 yuan/kilowatt of initial cost hereinafter, the electric cost of equivalent degree is 1.1 yuan~1.2 yuan/degree, the year two thousand twenty is arrived, 10,000 yuan/kilowatt may be dropped to hereinafter, cost of electricity-generating will be reduced to 0.4-0.7/ degree, When will form the condition of large-scale promotion application.At that time, China's solar power generation will be provided with establishing 100 MW class sunlight heats hair The designed capacity in power station.No heat accumulation power station installation cost is 1.68 yuan/kilowatt, 8 hours heat accumulation power station costs of band are 2.2 ten thousand yuan/ Kilowatt, rate for incorporation into the power network is less than 0.9 yuan/kilowatt hour).
More than this project can solve the problems, such as, the present invention will provide a kind of solar tower photo-thermal and photovoltaic power generation apparatus, together Existing solar groove type, tower, dish-style are compared with the technology of several introductions such as linear Fresnel formula, and solar tower power station is taken up an area less, At low cost, construction period is short, and water consumption is few, and structure is reliable, full-automatic, easy to operate, adapts to northern southern area, can scale Metaplasia production can reach to go up north and extensively wait areas, administering haze effect can significantly solve in short-term a large amount of uses, in the not too long of time It is kind, it benefits the nation and the people.Photovoltaic battery panel with tracking can multiple electric 30%, power generation does not need fuel, once build up it is lifelong be benefited, Service life is up to 30 years.The present invention has the characteristics that heat utilization rate is high, floor space is small and not waste water resource.Profit of the invention Taken up an area with column foot few, space is big, and the feature for making full use of space sunlight area big generates electricity, and more electric energy can be obtained. The pressure reservoir that the steam pressure of thermal energy is changed to normal-temperature water gets up, and meets requirement of the intelligent grid to power supply, it is ensured that electricity consumption is pacified Entirely, while feature at low cost is had both.
