audience is the underground museum exhibition national grid smart grid model to visit the green. The reporter Peixin She
pushing the national grid smart grid is on the rise for the national strategy to gradually introduce a series of industry standards related to the industry during a tremendous impact. June 29, the National Network issued a "smart grid technology standard system planning" and "smart grid key equipment (system) development plan" in 2011 and 2015 amendments to add the required technical standards, the basic technical standards into the smart grid system.
7 26, National Grid vice president Luan military to the media that the National Network for the International Electrotechnical Commission (IE C) standards of 18 proposals put forward, which marks the official launch of the Smart Grid China standard process of internationalization.
reporter recently interviewed a number of experts believe that, although China's smart grid standards have a tendency to international standards, but is still in the light of national conditions and make smart grid, renewable energy for achieving access and increased energy utilization has a huge significance. In addition, the introduction of smart grid standards almost immediate impact on the industry.
a number of smart grid were IEC international standard proposal approved
Reporters from the national grid Museum of Shanghai World Expo's theme of special events, the forum was informed that National Grid has been proposed, including user IE C side of the interface charging and discharging of electric vehicles, smart scheduling, etc., including 18 proposed standards, three of which proposals have been approved by the IEC.
According to Luan military, the State Grid Corporation of IEC Market Strategy Board is a full member, actively participate in IEC / SM B UHV strategic group, strategic groups on the smart grid work in the preparation of the IEC smart grid standardization roadmap. In the international standardization organizations, supported by the State Grid Corporation of affiliated HVDC IE C standard committee as a platform to actively work.
Luan military said in a UHV power transmission, high voltage / high voltage direct current transmission, the National Grid proposals put forward eight standards, including "HVDC grounding specifications, high-voltage direct current transmission line electromagnetic environment limits, HVDC system reliability and availability assessment "and other three IE C has received the approval; user-side interface in the smart grid, electric vehicle charging and discharging, intelligent scheduling and other aspects of the 10 proposed standards, including" User side of the device connected to interact with the network interface standard "," user-side power into the grid technology standards "and" metering and billing of electric car charging and discharging device "and so on.
Currently, National Grid has a number of research institutions and signed a strategic cooperation agreement, initially identified in electric cars, things, and sensors, smart cities and large-capacity storage system 4 in the study jointly carried out with standard preparation. "We will continue to work with power companies, manufacturing enterprises, research institutions, universities, trade associations and other multi-party cooperation in the IE C and other international standards organizations support the establishment of cross-platform communication and cooperation mechanisms." Luan military said.
IE C Vice calendar thinking that, IE C actively participate in international standardization of the smart grid, for example, and the United States N IST (U.S. National Institute of Standards and Technology) in close cooperation to develop standards to ensure that the smart grid equipment and systems interoperability, the current N IST has adopted many of IEC International Standards. At the same time Europe is also seeking similar cooperation mechanism, "Dresdner agreement in the context of Europe want IE C able to develop a smart grid to achieve regional interoperability standards." Historical thinking to the presence of the media said.
It is understood that Dresdner agreement by the CENELEC (European Committee for Electrotechnical Standardization) and IE C signed in Germany in 1996. Agreement between the two sides of the new standards project, "joint planning and parallel voting" system, including: speed up the publication and adoption of common international standards; to ensure rational use of resources to ensure that the content of the technical standard is the international standard; to adapt to the market needs to accelerate standards development process; joint planning of new projects.
However, due to China's primary energy distribution is very uneven development of productive forces, such as 2 / 3 of the coal resources in the north, 2 / 3 of the hydropower resources in the southwest, the land wind power concentrated in the northwest, and 2 / 3 of the energy consumption in the eastern region. China's wind power, solar power is mainly in the desert, the Gobi Desert and other remote areas focus on development of large capacity, small-scale local power grid, can not be used locally, need access to large high-voltage grid, to achieve the long-distance power transmission and a wide range of consumptive . Chinese Academy of Sciences, Academy of Engineering, Pan Jiazheng, believes that the development of high voltage energy center and economic center for the uneven distribution of China is particularly necessary.
experts in the "Economic Information Daily" reporters, also said that construction of China's strong intelligence network, the United States or other developed countries can not copy the development model grid, but to work closely with China's social and economic development and energy endowment characteristics, in line with China's national conditions take the road of sustainable development network.
State Grid Power Research Institute, deputy chief engineer Jian-Guo Yao that the smart grid standards, to take care of our country's overall situation, the industry also play a leading role in technological progress, "China's energy resources and distribution of productive forces showed a reverse distribution, must be on the basis of a strong grid smart grid, strong grid left, intelligence is empty; and Europe with a focus on the smart grid electricity, it is because they already have a strong grid, we building a strong and smart grid is a two-step for step, with the electric field so we can digest and absorb some of the international standards with national conditions of China, construction of smart grid network conditions, but the ultimate goal and abroad is the same, are available to achieve renewable energy electricity users flexible access and two-way interaction, which was used to improve energy efficiency, low-carbon development. "Jian-Guo Yao told the" Economic Information Daily "correspondent.
a huge impact on the industry standard
end of June, National Grid issued a "smart grid technology company National Grid planning standards" and "smart grid key equipment (system) development plan." According to the State Grid Corporation of Yi-Min Wang, director of the smart grid, the "smart grid technology standard system planning" is used to guide the State Grid Corporation of smart grid business standards for the preparation of programmatic documents and technical guidelines, but also China's smart grid industry standards and national standards for the preparation of important reference work; "smart grid key equipment (system) development planning" is the key equipment development work program of action, as scientific research, manufacturing equipment development guidelines, and also as the development of related industrial development planning guidance basis.
According to Luan Jun introduction, smart grid technology standard system consists of "eight professional branches, 26 technology, 92 standard series, a number of specific criteria," components. It is reported that eight professional branch is "comprehensive and planning, power generation, transmission, substation, distribution, consumption, scheduling, communication and information", each containing a number of specialized branches and specific standards. The "power" as an example, in the "power" in the three technical fields, involving 12 series of standards. Such as "new energy power generation access network technology provides standard series" has been released to include the "technical requirements for wind farms connected to the grid" and "grid technology provides access to photovoltaic power plant", the standard series will be completed this year. There also will be completed this year, "the power of information collection terminal equipment and systems series of standards", "power side of the communication specification standard series", etc., since these standards will support smart grid pilot demonstration project construction.
Reporters learned that in December last year to develop and publish national grid smart energy meter of 12 company, covers 11 categories of four kinds of smart meter accuracy level; information collection systems in the power released by 24 key corporate standards; in electric vehicle charging facilities, 11 companies issued standards covering AC charging pile, non-car charger, charging station, charging port and charging control systems.
Zhongtian Technology Co., Ltd., Xue Jiping to the media, said: "In the past, technical standards are often the product has been developed and run after the introduction, lags behind, it could lead to incompatibility between products. "Xue Jiping that the release of Smart Grid standards, reversing the standard delay the introduction of the disadvantages, but also a waste of resources and avoid duplication of investment, regulate the orderly competition in the industry, reducing production costs.
XJ Group Corporation, president of Fu-Sheng Li also believes that smart grid technology, the standard maximum impact is reflected in the product development from design to construction, operation and maintenance of the whole process can play a guiding role.
Reporters learned from the industry, not only for smart grid technology standard things technology, Internet technology and information technology for the organic combination will make the integration technology to a wider range of applications. Analysis of the industry, which will lead to the existing power transmission products, in particular, is a breakthrough in the original boundaries of the two devices penetrate each other, so that commonly used switching equipment, transmission lines, transformers into a number of intelligent elements, such as can be real-time monitoring can be achieved for the occurrence of a simple failure handling. Naturally, this will also break the original equipment manufacturers in the market, triggering a new round of market competition in the manufacturing sector.
to industry sources, the main industries involved in smart grid, including new energy power generation and networks, composites, wire and cable, power distribution, measuring and testing, power system automation, energy storage, electric vehicles, access, communication and information. With the smart grid construction from planning into actual construction, with the smart grid-related equipment manufacturers will be significant incremental market, such as NARI, Siyuan Electric, XJ Electric and Hidenobu stake. Reporters learned that there are many equipment manufacturers take the lead in large-scale construction for the Smart Grid do your homework.
