There are significant limitation, energy-saving and emission-reduction and sustainable development are the fundamental state policies in China, green for regional use of source deficiency
The ladder of the energy using the only way for being the following national economic development, China some areas due to power grid receive scarce capacity,
Wind electric field blower pause in part caused by the own characteristics such as the Construction of Wind Power duration mismatches and wind-powered electricity generation is unstable, causes to abandon wind limit
Electrical phenomena, wastes the new energy such as substantial amounts of resource, solar energy there is also analogue, according to meteorological data in all parts of the country and
Correlative study report can prove that solar energy and wind energy resources have extraordinary complementarity：From the point of view of whole year, typically too
It is positive can summer it is more abundant, and wind energy winter is relatively abundanter, from the point of view of one day, more abundant fine of solar energy
On the date, wind-force is usually then weaker, and wind-force mainly appears on night and morning, and wind energy and solar energy has complementary well, night
Evening, power grid electric power consumption was far below the power consumption on daytime, causes substantial amounts of electric power when people are stopped rest
Waste, country, which has put into effect night the charge of electricity, reduces policy, is commonly called as " paddy electricity ", how to make good use of wind and solar energy and paddy electricity is value
The thing that must be thought deeply and study, and the cause benefited the nation and the people, traditional hot-blast stove obtain heat source using burning
Mode, as the policy of national energy-saving emission reduction constantly becomes tight, boiler newly-built and using low capacity has all been forbidden in many areas, so
And people need this small-power hot wind to be produced and lived really in many places, the thermal efficiency of hot-blast stove how is overcome
Low, the shortcomings that pollutant emission is big is to be worth technical staff's research and explore, and the prior art is urgently to be modified and development.
The content of the invention
The trough-electricity of night low electricity price is utilized when wind light mutual complementing supplies electric energy insufficient the object of the present invention is to provide a kind of
Supplement energy storage or accumulation of heat are carried out, to provide the wind light mutual complementing paddy electricity energy storage hot blast stove system of endlessly clean energy resource.
The used to achieve the above object technical solution of the present invention is：A kind of wind light mutual complementing paddy electricity energy storage hot-blast stove
System, including wind power generation plant, device of solar generating, paddy electricity introducing device, new energy controller, storage battery group, inversion
