Description
Technical field
It is optimal the present invention relates to a kind of building method of photovoltaic plant, more particularly to a kind of mountain region photovoltaic power station component due south
The three-dimensional method for arranging at inclination angle.
Background technology
Under global energy-saving and emission-reduction, the huge challenge of energy security, Renewable Energy Development turns into crisis era after promotion
Economic transition, the important means of development low-carbon economy.As a series of favourable support policy of country is put into effect, photovoltaic industry is obtained
Flourish, the construction installed capacity promotion year by year of domestic photovoltaic plant, it is contemplated that the year two thousand twenty whole nation total installed capacity scale is up to
150GW。
Conventional large-scale ground photovoltaic plant is mainly built in the relatively flat area of physical features, in recent years as physical features is flat,
The good land resource of construction condition is increasingly reduced, and can not meet the photovoltaic plant construction during flourishing, and sight is gradually thrown
To the terrain that hills, mountain region etc. are complicated.
Existing mountain region photovoltaic plant construction component method for arranging is multimodal various both at home and abroad, and comprehensive analysis can mainly return
It is two major classes：One is using the support for lengthening photovoltaic array, making up the ground potential difference that landform is caused so that photovoltaic module is in most
Good inclination angle due south direction laying；The second is the arrangement of photovoltaic module complies with mountain topography tendency, the basic phase of length of bracket upright post
Together, the direction of each array is inconsistent, and making up construction difficulty and cost using the loss of generated energy increases so that photovoltaic module array
The anon-normal Southern Dynasties to.
However, traditional component arrangement has the defect and deficiency of many, make up ground using bracket upright post is lengthened
Potential difference causes component towards the method for arranging in due south, is primarily present following defect：1st, bracket upright post needs to lengthen, and each not phase of length
Together, on-site cutting is needed, material and construction cost are high；2nd, because column is lengthened, there is the ladder discrepancy in elevation, shadow occlusion between adjacent array
Scope is big, and land seizure amount is big, and the gradient is bigger, and latitude is higher, and land seizure amount is bigger；3rd, column is different in size, to support
The stability of equilibrium of structure proposes challenge higher, and the structure of support is more prone to unbalanced stability hidden danger.
The photovoltaic module method for arranging of mountain topography tendency is complied with, following defect is primarily present：1st, component arrangement complies with mountain
Ground landform arrangement, towards each inconsistent, the anon-normal Southern Dynasties subtracts to the photovoltaic module arranged on hillside, the solar radiation quantity that whole year receives
It is few, decrease of power generation；2nd, photovoltaic module array, towards each inconsistent, exist between array and matches poor, shadow towards consistent with hillside
Generating efficiency is rung, and it is larger to the influence of fading of photovoltaic module；
Additionally, using traditional component method for arranging, larger levelling of the land engineering is generally needed in process of construction, not only increase
Engineering cost and difficulty of construction are added, and destruction have been caused to pre-existing topography, recovered original appearance or the original stability in hillside, needed
Extra slope protection works is wanted, if bank protection is improper, it is possible to sandstone can be caused to tumble, mud-rock flow, the phenomenon such as landslide, brought to power station
Huge risk.
The content of the invention
Defect and deficiency in order to overcome prior art of the invention, there is provided a kind of generating efficiency is high, and adaptation function is strong,

Plane where the most inclination angle of positive amount of radiation.
Described photovoltaic array 4 is made up of Board Lot photovoltaic module, photovoltaic bracket and array basis.Described light
Volt support can be adjusted, and adapt to the change that photovoltaic module rotates angle between photovoltaic array and horizontal plane in optimum angle of incidence plane 1.
Described intersection 3 is that 2 two planes domatic with hillside of optimum angle of incidence plane 1 intersect produced intersection.
A kind of three-dimensional method for arranging of mountain region photovoltaic power station component due south optimum angle of incidence as described above, photovoltaic module is most
Rotate in good camber plane 1, do not depart from optimum angle of incidence plane 1, it is ensured that photovoltaic module due south towards and annual receive too
Positive energy amount of radiation is maximum.When photovoltaic module turns to a certain special angle, photovoltaic module side is parallel to optimum angle of incidence plane 1 and mountain
The intersecting intersection 3 in slope domatic 2 so that the photovoltaic array 4 of the photovoltaic module, photovoltaic bracket and array basis composition of Board Lot is flat
Row in intersection 3, parallel to intersection 4 arrange, so the bracket upright post 5 highly basic of photovoltaic array 3 by the basis edge of photovoltaic array 4
Cause.
A kind of three-dimensional method for arranging of mountain region photovoltaic power station component due south optimum angle of incidence as described above, same photovoltaic plant
Building site, longitude and latitude difference is smaller, and the change of pitch angle of optimum angle of incidence plane 1 can be ignored.But mountain topography is complicated, rise
Volt is indefinite, towards different, causes the optimum angle of incidence plane intersection complications for intersecting domatic with hillside to differ.A kind of described mountain region light
The three-dimensional method for arranging of overhead utility component due south optimum angle of incidence, by the fine direction and the gradient for dividing mountain topography, strictly will
The region division that direction and the gradient change within the specific limits divides mountain topography direction and the gradient in same plot region
Into the plot region that several change within the specific limits, in plot region as described above, can be by adjusting basic top mark
Height, the photovoltaic array arranged in the region of plot is adjusted to the mountain region of identical direction and the gradient so that in same plot region
