Editor's note on December 2, 2015, the ministry of land and resources in the form of normative documents issued the photovoltaic power station project land control indicators (land and capital rules  11, hereinafter referred to as the "indicator"), specific implementation since January 1, 2016. The index's, fill the industry (energy) land standard in the field of a blank. Why do you want to publish such a land use control indicators? What type of pv projects "indicator" is mainly used? Specific how to ensure the economical and intensive land use pv projects? Our guest the ministry of land and resources department of land use is the indicators establishment and implementation of the necessity, the main contents of the indicators and several problems that need to highlight any preliminary interpretation.
Why release photovoltaic land control indicators?
Fill the industry standard (energy) land a void
Compiling and publishing implementing land use control indicators photovoltaic power station project "(hereinafter referred to as the" indicator "), is to implement the central about "to establish the strict system of economical and intensive land use" and "about making the 13th five-year plan for national economic and social development's advice," stressed "adhere to the strictest economical use of land system", the important measures is to implement the state council on promoting the economical and intensive land use of the circular (guo fa  no. 3) put forward "to perfect the system of all kinds of standard construction land", "the state council on promoting the healthy development of photovoltaic industry several opinions (guo fa  no. 24) is proposed to speed up the formation of conducive to the sustained and healthy development of industry regulations, policies, standards, system and market environment, as well as the economical and intensive use of land regulations, land and resources ministry make no. 61) requirements" the state shall practise a system of construction project land use standard control ", "the ministry of land and resources under the state council in conjunction with the relevant departments to formulate the" index of land use control for engineering construction projects of specific measures.
Land for the construction project review, supply and use, shall be in conformity with the land use control index and land policy. Draw up the "index", make the photovoltaic engineering construction land from the top to have a standard control, is not only an important content, improve the system of land use control standards and standard control standard for examination and approval of land use and supply, an important means to promote the economical and intensive land use.
At present, the ministry of land and resources has alone or with the relevant departments jointly issued on the implementation of the project land indicators have 16, covering industrial, energy, transportation, water conservancy, public cultural and sports, etc. The promulgation of "indicators, fill in the industry standard (energy) land a void.
Promotion of photovoltaic power generation project economical and intensive land use
The current and future a period of photovoltaic industry is in rapid development stage in our country. As of October 2015, the national pv power station has a total installed capacity of 35 million kw or more, planning to 2030, the installed capacity will reach 100 million kilowatts. And photovoltaic industry development does not adapt, the current national level has not yet promulgated photovoltaic power generation project land use standard, local land for pv projects lack of follow basis, resulting in some project there is blindness in the land, there is a wide wide use, waste land problem.
Draw up the "standard", make the photovoltaic engineering construction land from the top to have a standard control, is beneficial to improve the system of land use control standards, approval and supply of land, promoting land for photovoltaic industry more standardized and intensive.
Regulate the behavior of photovoltaic power generation project land administrative examination and approval
In June 2012, ministry of housing and urban-rural development and the general administration of quality supervision, inspection and quarantine jointly issued "photovoltaic power station design specification" (GB50797-2012), the site selection of photovoltaic power station, power generation system, station layout, architecture and structure, the design specification, also on preparation of photovoltaic power station project land index requirements are put forward.
The indicators is the project units in the formulation of construction project feasibility study, planning and design stage to determine the important basis of land scale, is advantageous to the construction of photovoltaic power generation from project design, land use and land supply for examination and approval of land for unified standard, is the government department for examination and approval pre-examination of project feasibility study report, and the construction land approval project land area is an important measure.
Enforcement of the "index", which is beneficial to constrain project unit covers an area of impulse, promote the economical and intensive land use, as well as the competent department of land and resources at all levels and relevant departments of industry and the survey and design unit provides an important basis system specification.
Local related exploration and field investigation for the indicators to lay a good foundation
With the continuous expansion of photovoltaic power station construction in recent years, to regulate land use management, hebei, shaanxi, qinghai, ningxia and other places have carried out the photovoltaic power station project land use index compiled by the work, introduced standard pv projects land. the ministry of land and resources has also carried out a large number of research work in recent years, we have to send to the hebei QuYang CLP vote group constant sunlight v power stations, Lai source Jin Gujing photovoltaic power stations, Zhang Bei state grid landscape lost storage power station, qinghai, make and golmud pv power station has carried on the on-the-spot investigation. For pv projects are centered in hebei, Inner Mongolia, Shanghai, zhejiang, shandong, gansu, qinghai, ningxia provinces (autonomous regions and municipalities) 62 pv projects planning and design of the data analysis, preliminary mastered the photovoltaic functional zoning and land use scale of the project, for the indicators laid a good base for work.
The indicators is the important content of the body of the framework and how?
The general framework of indicators is divided into four parts, namely: the basic rules, photovoltaic power station project land use overall index, single index and the appendix.
Basic rules made clear the scope of the journal index, index, general index and the effect of single parameter applicable link, emphasized on economical and intensive land use photovoltaic engineering construction project site selection, layout, management, facilities and construction of ancillary facilities shall follow the principles and rules.
Overall indicator is on the total scale of the overall control standards for land use in photovoltaic power generation project. Internationally, photovoltaic power generation capacity to 10 mw photovoltaic power station as the basic unit. Therefore, the land for project area also to 10 mw photovoltaic power station area as the basic unit. According to specification for design of photovoltaic power station, the impact of photovoltaic power station project covers an area of the size of the factors mainly include: the location of the photovoltaic modules of the whole area of efficiency, dimension, terrain conditions, photovoltaic panels battery conversion efficiency, photovoltaic phalanx pattern and the level of substation booster. In general, the higher the latitude, covers an area of the greater; The higher the conversion efficiency, covers an area of less.
Overall index to classification list type, that is, according to the topography of the land occupied and photovoltaic phalanx pattern classification, a total of 12 types of overall index list, in the table according to the dimension of different regions, different power generation efficiency, different boosting conditions such as grade, one-to-one corresponding parameter values are given. Work, according to the specific situation of photovoltaic power generation project, the amount of land used for directly query the corresponding values in the table.
The indicators on the basis of photovoltaic power generation project of four single parameter specified in the functional partition, respectively is: photovoltaic phalanx land indicators, substation and operation management center land, land for collecting circuit and field road land indicators. Among them, the index of land for photovoltaic phalanx, according to the different way of square arrangement, lists the stationary, flat uniaxial tracking methods, oblique uniaxial tracking methods and two-axis tracking index table for four square; Substation and operation management center index of land use, according to the different level of booster, respectively is a list of 5 kinds of other land use indexes such as table; Collecting line index of land use, depending on the type of pole, lists the concrete pole and tower pole land index table.
For convenience of practical work in master of photovoltaic power generation project land index measurement, the index set up two appendices. Appendix A municipality directly under the central government and provincial capital cities are given cant daily average radiation photovoltaic array reference value. Appendix B gives the equator coordinates two-axis tracking square land index calculation method and so on 8 types of calculation method and main points, and 12 calculating examples are listed.
Photovoltaic (pv) land control indicators which need special attention?
Is really necessary, super size land project shall carry out construction project evaluation section
The indicators is photovoltaic engineering project design, feasibility study, use pre-examination and approval, land supply, and for regulatory standards and basis, after is the competent department of land and resources, land unit, survey and design unit, abide by the regulations by the competent department of related industries. And highway, railway, airport, power and other land for the project indicators, the indicators for the land use scale limit control, namely the land scale should be within the scope of the "indicator" control, should not break through the index of certain scale. More than indicators to determine the land use scale, should subtract land.
Because of production safety, topography, technology truly have special requirements, such as unable to subtract land, shall be based on the general office of the ministry of land and resources of specification section of the construction project evaluation work notice (land resources hall hair  no. 16) requirements, carry out evaluation of arguments.
Especially to be sure, index of land referred to in land use including farmland, construction land and unused land, no matter use what kind of land, according to the index to determine the land use scale.
Scope of application of the indicators is the ground of the construction, rebuilding and expansion of photovoltaic power station project
Solar photovoltaics are mainly ground centralized photovoltaic power generation and distributed photovoltaic two forms. Ground centralized photovoltaic power generation is in the ground installation photovoltaic phalanx components, photovoltaic power plant at present domestic large and medium-sized the main ground photovoltaic ways; The daylighting of distributed photovoltaic power generation is the use of the existing building installation of photovoltaic power generation materials, is widely used in city building material roof installation of photovoltaic power generation; Otherwise the water fishing light complementary photovoltaic, main is to use the pool, on the surface of the erection of photovoltaic panels to generate electricity. The above forms of photovoltaic power generation, light is distributed and the water fishing complementary power generation using of buildings and the surface are no need for new, for the ground photovoltaic involves the land, thus, the scope of application of the indicators is the ground of the construction, rebuilding and expansion of photovoltaic power station project.
Prepare the principles of the indicators
"Index" compiling work follow the following principles: one is based on the usual site conditions, the second is production equipment, process technology, planning and design elements such as advanced must reflect the average level, three is to protect farmland and the principle of economical and intensive use of land. (than) with the typical instances verification, the index has reached the average advanced level, in line with the requirements of economical and intensive land use.
The indicators in accordance with the relevant design specification and the actual land use situation to determine the functional partition
According to the regulation of national standard specifications for design of photovoltaic power station, solar power stations of the same total plane design include: photovoltaic phalanx, booster station (or switching station), on-site set electric circuit, in situ inverter booster station, Station Road facilities and other protective function (flood, lightning, fire prevention) 6 parts. From field survey, the land for photovoltaic power station mainly include photovoltaic phalanx, substation and operation management center land, land for collecting circuit, field road four parts, each part includes specifications for design of photovoltaic power station involves the specific function of land use. Therefore, the indicators of the photovoltaic power generation project land functional partition into the above four parts.
The indicators of the overall index and functional zoning index of different effects
In photovoltaic power station project feasibility study stage, the general scale of land for each functional partition is not yet clear, at this stage, mainly according to the approved land use general index scale. And functional zoning index mainly in the planning and design stage, use pre-examination and approval stage is used to check and ratify the amount of land used for partition.
The indicators for the land use scale of check and ratify the dual control. When a pv projects land for each functional partition size meet the index, the total land scale will generally conform to the land use index. And when a photovoltaic project in line with the overall index, but some functional partition and the provisions of the land use scale than the single parameter is not meet the requirements of the "index".
In addition, the overall index is the size of the containing all the functional zoning of land, but some projects do not necessarily include land use index all functional partition, then in the verification of its scale, you need to use land for each functional partition index.
The indicators for high latitudes inefficient photovoltaic power generation project set up new land cap
According to the state council on promoting the healthy development of photovoltaic industry several opinions (guo fa  no. 24), to encourage the advanced technology, high energy consumption, low efficiency of photovoltaic capacity, on the next new photovoltaic manufacturing project should be full, foot monocrystalline silicon solar cell conversion efficiency is not lower than 20%, polycrystalline silicon solar cell conversion efficiency is not lower than 18%, thin film solar cells conversion efficiency of no less than 12%.
For the implementation of the national industrial policy, the indicators with low efficiency for high latitudes in the photovoltaic modules of project 10 mw photovoltaic phalanx land 100 hectares of upper limit control standards, to effectively control new projects such as high latitudes.
