Abstract
The utility model relates to a terrestrial photovoltaic electric field array system structure, which is formed by four photovoltaic arrays and a power distribution room. The array system presents a shape of a Chinese character 'field' in the planar view, the power distribution room is arranged at the central position of the whole terrestrial photovoltaic electric field array system, the four photovoltaic arrays are relatively and electrically independent and respectively connected into four inverters, and the four inverters are combined together into a booster system. Accordingly, by using passages among the four photovoltaic arrays to neutralize partial shadow blocking of the power distribution room, the terrestrial photovoltaic array electric field array system structure leads arrangement of the photovoltaic arrays to be compact and reasonable, improves ground use rate, simultaneously saves cables and reduces loss to the lowest level, and additionally if one of the four photovoltaic arrays fails, normal running of the other photovoltaic arrays is not affected.
Description
Technical field
The utility model relates to a kind of ground light photovoltaic electric field matrix architecture that photovoltaic arrays and electric equipment are arranged, and this gust system all can be used in independent photovoltaic power station, ground and large-scale grid-connected photovoltaic power station.
Background technology
At present, a photovoltaic arrays and a switchgear house constitute a ground light photovoltaic electric field matrix system.Switchgear house is positioned at outside the photovoltaic arrays, and built-in electric equipment is connected with photovoltaic arrays with cable.Switchgear house can block the photovoltaic array generation owing to sunlight forms shade, cause photovoltaic electric field poor efficiency for avoiding on photovoltaic arrays, producing shade, distance between switchgear house and photovoltaic arrays will meet certain requirements, cause this ground light photovoltaic electric field matrix system need be with a large amount of cables, cost is higher, and loss is bigger.
Summary of the invention
Utility model purpose: in order to overcome cable large usage quantity in the existing ground light photovoltaic electric field matrix system, deficiency that loss is bigger, the utility model provides a kind of ground light photovoltaic electric field matrix architecture, block shade the sunshine that this structure can effectively avoid switchgear house to produce, and saving cable, reduce cost, reduce loss.
The utility model is for realizing that above-mentioned utility model purpose adopts following technical scheme:
A kind of ground light photovoltaic electric field matrix architecture, comprise photovoltaic arrays and switchgear house, described photovoltaic arrays is four, these four photovoltaic arrays divide the both sides, north and south, four quadrants are arranged, to constitute the ground light photovoltaic electric field matrix system, its plane is sphere of movements for the elephants shape, switchgear house then places in the photovoltaic arrays with a quadrant of many direction homonymy of solar radiation time the position near the ground photovoltaic electric field matrix system origin of coordinates, each photovoltaic arrays electric energy output end all is connected with an inverter respectively, and be connected with an AC distribution device jointly with the inverter of the corresponding connection of each photovoltaic arrays electric energy output end respectively, this AC distribution device output then is connected with increasing apparatus.
Preferably, be respectively arranged with two passages in East and West direction and north-south between four photovoltaic arrays of ground light photovoltaic electric field matrix architecture of the present utility model.
Beneficial effect
Ground light photovoltaic electric field matrix architecture described in the utility model is seen from the plane and is sphere of movements for the elephants shape, closing on switchgear house has the two passes in East and West direction and north-south respectively, when for example being positioned at the Northern Hemisphere, can partly offset the east that switchgear house produces, shade (switchgear house places third quadrant) or west are blocked in the north side, shade (switchgear house places four-quadrant) is blocked in the north side, be that it is provided with the spacing of utilizing passage payment part shade to block in square formation system, and the line space that has utilized photovoltaic module is as the East and West direction passage, make and the photovoltaic array compact and reasonable arrangement improve land utilization ratio; Because switchgear house occupy the center of whole ground photovoltaic electric field matrix system, and used cable is saved most, loss is also minimum in addition; If four one of them square formations of square formation have produced fault simultaneously, can not have influence on the normal operation of other photovoltaic arrays.
Description of drawings
Fig. 1 (a), Fig. 1 (b) are respectively photovoltaic array layout plans of the present utility model.
Fig. 2 is an electrical system line chart of the present utility model.
Embodiment
Explain the technical solution of the utility model below with reference to accompanying drawing.
Shown in Fig. 1 (a), Fig. 1 (b), ground light photovoltaic electric field matrix architecture described in the utility model, comprise the photovoltaic arrays formed by a plurality of photovoltaic modulies and switchgear house 5., described photovoltaic arrays be four 1., 2., 3., 4., 1., 2., 3., 4. these four photovoltaic arrays divide four quadrants to arrange that its plane is sphere of movements for the elephants shape to constitute the ground light photovoltaic electric field matrix system.Because the point of vertical of the sun changes between the tropic of north and south, when being in the Northern Hemisphere, zone between the tropic of north and south is positioned at the south, naturally the solar radiation of accepting in the south is many, switchgear house 5. place third quadrant 3. or four-quadrant 4. in the photovoltaic arrays near the position of the ground photovoltaic electric field matrix system origin of coordinates, and switchgear house has the two passes in East and West direction and north-south near 5. respectively, the spacing of so just utilizing passage payment part sunlight shade to block has been reduced or remitted because shade causes photovoltaic electric field poor efficiency; Then opposite when being positioned at the Southern Hemisphere, the zone between the tropic of north and south is positioned at the north, and the solar radiation that natural north is accepted is many, then switchgear house 5. place first quartile 1. or second quadrant 2. in the photovoltaic arrays near the position of the ground photovoltaic electric field matrix system origin of coordinates.
In addition as shown in Figure 2, photovoltaic arrays of its every line display 1., 2., 3. or the subsystem formed of battery component 4., this battery component comprises photovoltaic power generation array A, DC distribution monitoring device B, inverter C, AC distribution device D and increasing apparatus E, described photovoltaic power generation array A electric energy output end is connected with an inverter C by DC distribution monitoring system B, then be connected with an AC distribution device D jointly with the inverter C of the corresponding connection of each photovoltaic power generation array A electric energy output end respectively, this AC distribution device D output then is connected with increasing apparatus E.
