Technical field
The present invention relates to photovoltaic control system, specifically relate to a kind of voltage stabilization and current stabilization, efficient energy-saving ground PV_LED efficiently controls distribution system.
Background technology
Only a kind of cleaning, regenerative resource, solar energy resources is widely distributed in China.Because China is the big country of an energy resource consumption and energy skewness, therefore develops solar photovoltaic generation system and have great importance for the sustainable development of China.
The solar power generation that exists in the market has two kinds of technology, and a kind of is the solar photovoltaic grid-connection contravariant generating system technology that country is carrying out energetically.This technology mainly is that the solar photovoltaic electric power that will have the direct current characteristics is exported to the electrical network that exchanges, and carries out accumulation of energy by national grid.The solar photovoltaic grid-connection power station of this inversion is converted in the inversion process of interchange at direct current, lost photovoltaic electric weight greatly, although thereby this solar energy power generating is technically, all feasible in the application, be fully infeasible economically.The cost of at present solar energy power generating is also very high, is about 3 yuan/degree electricity, so in fact the photovoltaic of this parallel network reverse is used and can not be walked far.And another kind of technology is to adopt off-grid photovoltaic application mode, and this technology mainly is to be applied in road lamp system, isolated island small plant " user of family uses system " etc.Photovoltaic also has two kinds of technology of inversion and direct current from net mode, but because the uncertainty of photovoltaic, is exactly the technology that charges a battery so the off-grid system of photovoltaic adopts, by the storage battery powering load.When power load was larger, solar electric power was not enough, just borrowed electricity to civil power.When load hour, or just fully waste of exhaustless solar electric power.The technology that charges a battery comprises inversion or direct current in the control system; To the technology such as super-charge super-discharge protection of storage battery, finally all still provide electric energy by storage battery to load, any once conversion of energy is all lost produce power; From designing, storage battery is a fixing power match, and photovoltaic is a dynamic Power supply.Therefore the power generation loss is self-evident.Because the present cost of battery component is high, this generating that can not utilize solar energy fully, so that the photovoltaic cost is far longer than civil power certainly, thereby feasibility is low.Can not apply.
Summary of the invention
The objective of the invention is to use the defective that exists for above photovoltaic, a kind of crystal silicon solar photovoltaic cell component that proposes, the nano-silicon storage battery of solar energy special use, ternary power supply (photovoltaic priority principle) DC load of civil power, the PV_LED of the binary electricity consumption of the nano-silicon storage battery of solar energy special use efficiently controls distribution system.
The present invention is taked the ground technical scheme to be by its purpose of realization: PV LED efficiently controls distribution system, be one and use the Based Intelligent Control distribution system that designs for photovoltaic specially, comprise the crystal silicon solar photovoltaic cell component, the nano-silicon storage battery of solar energy special use, controller, DC load, adopt the crystal silicon solar photovoltaic cell component directly to connect with efficient controller, pass through control device, make the uncertain of photovoltaic and with the variability of electric loading, under the adjusting through the accumulation of energy function of the nano-silicon storage battery of solar energy special use, the electric weight of photovoltaic is all finished using.The present invention adopts the crystal silicon solar photovoltaic cell component to generate electricity.In the situation of illumination abundance, the crystal silicon solar photovoltaic cell component is direct current measurement with light energy conversion directly, for the architectural lighting load.(such as underground garage, needs electricity consumption in 24 hours) can directly use solar energy power generating daytime in the public illumination of building.In the configuration and design of system, photovoltaic is with Changes in weather, and according to the general requirement of DC load, configuration can provide the photovoltaic power consumption of public building illumination on daytime.Be all direct current system, photovoltaic directly drives the dc lighting load; When solar energy is very strong, the energy output of mono-crystalline silicon solar photovoltaic cell component has surpassed the power consumption that makes of load, unnecessary electric weight just stores in the nano-silicon storage battery of solar energy special use efficiently by system's control, the needs of electric consumption on lighting when evening, solar energy no longer generated electricity with supply.When long-term illumination was not enough, when namely accumulation of energy did not reach the power consumption of night lighting load, awarding suitably by civil power, charging replenished.
Described load is to have the LED light fixture of direct current character and DC magnet ring lamp.The public illumination that is mainly used in building, in application process, the LED of delay and DC magnet ring lamp can be according to own characteristics, and design is lighted the time, according to the electricity consumption needs, under Based Intelligent Control, presents variable condition.
Described PV_LED efficiently controls distribution system, solar photovoltaic power plant average efficiency than present parallel network reverse exceeds more than 5 times, than to the nano-silicon charge in batteries of solar energy special use, provide the off-grid type photovoltaic of power supply to use average efficiency by the nano-silicon storage battery of solar energy special use and double above.
Described solar cell generally adopts the crystal silicon solar photovoltaic cell component, also can adopt other solar-energy photo-voltaic cell.The utility ratio of photovoltaic almost is 100%.
Beneficial effect of the present invention: the invention solves the problems such as pv grid-connected plant and the existing efficient of off-grid type solar energy power generating are low.It is the revolution that photovoltaic is used, and has broken through the economic bottleneck of photovoltaic application.It has abandoned the application mode of traditional photovoltaic fully, pass through Based Intelligent Control, in conjunction with also directly using, it is carried out complementary ground power-generation energy-storage with the nano-silicon storage battery of employing solar energy special use and electricity consumption is additional the electric consumption on lighting of the photovoltaic of variation and LED variation.Long-term overcast and rainy photovoltaic insufficient section is suitably replenished.The photovoltaic electric weight all can be finished using.Proved also in the practice that this product has economic worth very much.This technology is according to the DC characteristic to photovoltaic, and efficient application makes efficient obtain breakthrough raising to a special method of architectural lighting.
Be all semi-conductive LED and be combined with, substitute traditional lighting system, energy-saving effect is obvious.Power saving rate can reach more than 98%.System's long service life, simple, the dc low-voltage of maintenance; Reliability is high.All adopt automatic control technology, can be used for the zone of underground garage, corridor and garden illumination or the power supply shortage of public illumination.Can apply.
