In addition, although do not illustrate, in isoceles triangle top light volt booth shown in Figure 1; Adopt the formula fixed support that gathers that solar battery array is installed, that is to say, the solar battery array fixed installation; Very close to each other between the cell panel, fix with rubber strip and fixing glue.At the inboard insulation reflectorized material of laying of solar battery array, said insulation reflectorized material can be rolled and spread out as required.Lay sunlight board and ventilative skylight on the north slope face portion area.Junction adopts plastic-steel material and rubber strip to fix, the glass cement sealing, and structure is firm, prevents seepage.East, west, north facade adopt sealing brick wall insulation construction.South elevation adopts sunlight board to lay, and can have the mobile window of part.
Face the domatic angle of inclination, south and the relation of amount of radiation down and do brief description.
1) direct confirming of amount of radiation on the inclined plane
In engineering design, the direct amount of radiation in inclined plane adopts following formula to calculate:
R b=Hbt/Hb, wherein
Figure DEST_PATH_GSB00000615143800061
Rb: the ratio of direct amount of radiation on inclined plane and the horizontal plane;
h s: the sunset hour angle on the horizontal plane;
Hbt: direct solar radiation amount on the inclined plane;
Hb: direct solar radiation amount on the horizontal plane;
H ' s: the sunset hour angle on the inclined plane.
According to above formula,, can calculate direct solar radiation quantity on the s inclined plane, a certain inclination angle according to relevant parameters such as local geographic latitude, solar declination degree.
2) the confirming of sky amount of scatter radiation on the inclined plane
Adopt the Hay Model Calculation for the sky radiation amount.The Hay model thinks that the sky amount of scatter radiation is made up of with the equally distributed amount of scatter radiation two parts of all the other skies the amount of radiation of sun CD on the inclined plane, and its computing formula is:
Hdt = Hd [ H b H 0 Rb + 0.5 ( 1 - H b H 0 ) ( 1 + cos ( s ) ) ]
In the formula, Hb and Hd are respectively direct and amount of scatter radiation on the horizontal plane, and these two parameters are the meteorological station original observed data; Ho is a solar radiation quantity on the horizontal plane of exoatmosphere.
According to relevant parameters such as local geographic latitude, declination angles,, can calculate sky amount of scatter radiation on the s inclined plane, a certain inclination angle according to above-mentioned formula.
3) the ground return amount of radiation confirms
For towards the inclined plane in equator, its amount of radiation total amount also should comprise the reflected radiation amount from ground itself except direct amount of radiation and the amount of scatter radiation from sky from the sun, and its computing formula is:
Hrt=0.5ρH(1-cos(s))
In the formula: H is a total radiation on the horizontal plane, is direct amount of radiation and amount of scatter radiation sum on the horizontal plane, is the meteorological station original observed data; ρ is a ground surface reflectance.The face of land, this photovoltaic plant project place is the desert Gobi desert, and the face of land is dried sand ground.In view of the above, the ground surface reflectance of these bidding plans project place is taken as 18%.
The formula of solar radiation quantity is on the inclined plane:
Ht = HbRb + Hd [ H b H 0 Rb + 0.5 ( 1 - H b H 0 ) ( 1 + cos ( s ) ) ] + 0.5 ρH ( 1 -
cos ( s ) )
For the place of confirming, after direct solar radiation amount and the amount of scatter radiation, it is the function of independent variable that the direct amount of radiation on the inclined plane, amount of scatter radiation and ground return amount of radiation are with the inclination angle, inclined plane on known this area each month horizontal plane.Its functional relation can be expressed as following formula: Ht=Hbt (s)+Hdt (s)+Hrt (s)
Therefore,, answer selective light photovoltaic assembly array optimum angle of incidence, make the radiation amount Ht on the inclined plane reach maximum, thereby reach the maximum target of power station annual electricity generating capacity for the photovoltaic generating system of fixed array.
The preferred embodiment that the above is merely the utility model is not the protection domain that is used for limiting the utility model; The protection domain of the utility model is limited the claim in claims, and every equivalence variation of doing according to utility model and modification, all within the protection domain of the utility model patent.
