Abstract
The utility model provides a solar energy lasts power generation facility, it includes that consecutive photovoltaic module, direct current converge flow box, DC booster and dc -to -ac converter, the electric current that the direct current converges the flow box outflow passes through pass through behind the DC booster the electric wire netting is linked to the dc -to -ac converter. The utility model discloses an increase the DC booster before the dc -to -ac converter, the low pressure electric energy that makes photovoltaic module produce steps up through the DC booster, and the starting voltage that makes voltage after rising surpass the dc -to -ac converter even the not enough low -voltage that produces of illumination also can start the dc -to -ac converter, with the low piezoelectricity of this part also connected to the grid, realizes the electricity generation that lasts of solar energy.
Description
Technical field
This utility model relates to solar energy generation technology field, particularly relates to a kind of solar continuous TRT.
Background technology
Photovoltaic panel is exposed to sunlight, and starts generating, and electric current enters inverter after being confluxed by direct current conflux case.Inverter works
Time have one start voltage, only input voltage higher than start voltage time, inverter is just started working.When direct current conflux case is defeated
When going out the startup voltage that voltage is less than inverter, inverter can not work, and the electricity sent can not really be played effectiveness.True
On, in the case of illumination deficiency, although the electricity that photovoltaic cell issues can not promote inverter to work, but on circuit also now
Having electricity, simply voltage is low, and the electricity of this part low-voltage can not normally be connected to the grid at present, causes energy waste.
Therefore, the electricity of generation also can be made when how to realize illumination deficiency to be connected to the grid, become solar electrical energy generation problem to be solved.
Utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of solar continuous TRT,
The problem used for solving the low-voltage of photovoltaic module output in prior art to be connected to the grid.
For achieving the above object and other relevant purposes, this utility model provides a kind of solar continuous TRT, and it includes depending on
Secondary connected photovoltaic module, direct current conflux case, DC booster and inverter, the electric current that described direct current conflux case flows out is through institute
Electrical network is linked by described inverter after stating DC booster.
Preferably, the input voltage of described DC booster is Width funtion, and input voltage range is 10 volts to 900 volts.
Preferably, the output voltage of described DC booster is constant voltage.
Preferably, described DC booster is integrated with described direct current conflux case.
As it has been described above, solar continuous TRT of the present utility model, have the advantages that employing increases before inverter
Add DC booster, make the low-voltage electric energy that photovoltaic module produces, boost through DC booster, make the voltage after rising exceed inverter
Startup voltage, even if the low-voltage that illumination deficiency produces also can start inverter, this part low tension is also incorporated into electrical network, real
The lasting generating of existing solar energy.

Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art can be by this specification
Disclosed content understands other advantages of the present utility model and effect easily.
Refer to Fig. 1.It should be clear that structure depicted in this specification institute accompanying drawing, ratio, size etc., the most only in order to coordinate
Content disclosed in bright book, understands for those skilled in the art and reads, being not limited to this utility model enforceable
Qualifications, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size,
Do not affect under effect that this utility model can be generated by and the purpose that can reach, all should still fall in the skill disclosed in this utility model
In the range of art content can contain.Meanwhile, in this specification cited as " on ", D score, "left", "right", " middle "
And the term of " " etc., it being merely convenient to understanding of narration, and be not used to limit the enforceable scope of this utility model, it is relative
Being altered or modified of relation, is changing under technology contents without essence, when being also considered as the enforceable category of this utility model.
As it is shown in figure 1, this utility model provides a kind of solar continuous TRT, it photovoltaic module 1 including being sequentially connected,
Direct current conflux case 2, DC booster 3 and inverter 4, the electric current that described direct current conflux case 2 flows out is through described DC booster
Electrical network is linked by described inverter 4 after 3.This utility model sets up DC booster at inverter, when solar irradiation deficiency,
Photovoltaic module produces low-voltage electric energy, and this part low-voltage electric energy, after DC booster boosts, remains to be connected to the grid through inverter, real
Show solar continuous generating.
The input voltage of above-mentioned DC booster 3 is Width funtion, and input voltage range is 10 volts to 900 volts；DC booster 3
Output voltage be constant voltage.DC booster of the present utility model is when illumination deficiency, it is ensured that solar continuous generating, its
For the low-voltage direct electric boost produced by photovoltaic resistance, make galvanic voltage increase to more than inverter startup voltage, it is ensured that
The unidirectional current of low-voltage also can be collected the use that is connected to the grid.
The present embodiment only need to be on original photovoltaic plant wire structures, and the only outfan at direct current conflux case increases a direct current liter
Depressor module, just brings the lifting of generated energy, says from this point on, and its economic benefit is the hugest.The present embodiment will
DC booster is integrated with direct current conflux case, and it simplifies overall structure, does not increase the complexity of photovoltaic plant wiring.
In sum, solar continuous TRT of the present utility model, set up DC booster at inverter, work as solar irradiation
Time not enough, photovoltaic module produces low-voltage electric energy, and this part low-voltage electric energy, after DC booster boosts, remains to be incorporated to through inverter
Electrical network, it is achieved that solar continuous generating.So, this utility model effectively overcomes various shortcoming of the prior art and has height
Degree industrial utilization.
Above-described embodiment only illustrative principle of the present utility model and effect thereof, not for limiting this utility model.Any
Above-described embodiment all can be modified under spirit and the scope of the present utility model or change by those skilled in the art.
Therefore, such as art has usually intellectual without departing from the spirit disclosed in this utility model with under technological thought
