Propose technical challenges
When building smart grid becomes an important content of national development strategy, the national standards of existing technology and key equipment insufficient to support the smart grid construction, set up a system, perfect, open and new technologies with independent intellectual property rights system is imminent, in this context, formulated by the state grid corporation organization of the smart grid technology standard system should be formed.

"Standards are integrated into Internet of things technology, Internet technology, and integration technology, which is a huge challenge for device makers." Li fusheng, chief executive of hui group co., LTD.

The personage inside course of study analysis, the current Chinese power equipment manufacturers, mostly engaged in a single type of product research and development and production, it is not only conducive to intelligent product research and development in the future, to a large extent, will also face the danger of being eliminated by the integration with. After all, from the point of China's equipment manufacturing industry now, also lacks like ABB, Siemens has rich technology and the strength of industrial operation, more lack of multidisciplinary research and development personnel, as well as a full range of system solutions in a particular field. The lack of important scientific and technological elements such as modern production and assembly line will make them face more serious technical challenges in the intelligent direction of equipment.

"The introduction of smart grid technology standards will enable domestic enterprises and r&d departments and users to form a strategic alliance to form an organic combination of industry-university-research cooperation and jointly meet the challenges of new standards. At the same time, it will also increase the ability to resist the impact of foreign companies. Xue jiping, chairman of zhongtian technology co., LTD. This may be the best model for corporate development in the next few years.

Leading the research and development direction
"The development of the smart grid cannot be separated from optical communication and power transmission, especially the high-end cable of photoelectric composite." From the point of view of the product field, xue jiping expounded the development focus of the enterprise. "Zhongtian technology innovation and development of high-end optical cable involving intelligent electricity, intelligent power transmission, intelligent power distribution, intelligent five electricity, communications, information technology products, in line with the smart grid industry development direction. Furthermore, we are more willing to carry out r&d and production activities around smart grid technology standards.

In fact, zhongtian technology have been optimistic about the smart grid development opportunities, in 2009, has established the institute of science and technology research institute and special wire, wire and cable peg at the forefront of technology, technical reserves, set about from the terminal composite cables, to monitor wire and power cable, new energy into the net with special wire and so on three aspects has carried on the technology research. These are the products that the smart grid will need for some time to come, even though there is no more detailed requirement for the technology in the smart grid technology standards.

"Given a secondary equipment line as the research and development of intelligent equipment is broken, Xu Ji group has already started to intelligent equipment research and development, including smart substation, such as photoelectric transformer has a cutting-edge technology products." Li fusheng told reporters. At present, xu has to deal with two problems in production and research and development. One is that products without norms and standards should be standardized to the standard. The newly developed products should be implemented strictly according to the requirements of the smart grid standard system.

Cause industrial revolution
"In the past, technical standards were often introduced after the product had been developed and run, and it was relatively backward, which easily led to the incompatibility between products." Xue Jiping, said the release of the smart grid standards, reversing a standard lag of disadvantage, also avoid the waste of resources and repeated investment, norms and orderly competition of the industry, reduce the production cost of enterprises.

"But the biggest influence is reflected in smart grid technology standard, the product from design development to construction, operation and maintenance play a guiding role in the whole process, it will cause equipment industry a profound change." "Said li fusheng.

Smart grid technology standards not only combine the Internet of things technology, Internet technology and information technology, but also make integration technology more widely used. The personage inside course of study analysis, this causes the existing transmission products, especially the secondary equipment breakthrough the original boundaries and mutual penetration, the common switch equipment, transmission line, transformer products into some intelligent elements, such as the problems can be real-time monitoring, can realize the simple processing, etc. This will also break the original market pattern of the equipment manufacturing industry and trigger a new round of manufacturing market competition.

Extended reading: the formation of smart grid technology standards.

History: the Paris conference formally launched the standard research work.

International electrotechnical commission is the world's earliest non-governmental international electrotechnical standardization organization, its main purpose is to promote the electrician uniform international standards, promoting standardization in the field of electrical and electronics engineering and related aspects of international cooperation.

In April 2009, in order to promote the construction of smart grid, the international electrotechnical commission standardization administration organization founded the smart grid strategy working group, and held its first meeting in Paris, France, from China, the United States, Germany, France, Japan and other representatives of the 13 countries took part in the meeting, the meeting officially launched the standardization of smart grid research.

Status quo: countries actively promote standard construction.
China: in April 2010, the state grid corporation to establish the "smart grid technology standard system planning" report, the smart grid technology standard system planning system is proposed for the first time in China, including eight major branches, 92, 26 technology standard series of smart grid technology standard system, clear the need can be directly used, need to amend, develop smart-grid technology standards. According to the plan of smart grid technology standard system, the state grid corporation sets the technical standard of smart grid in three stages.

Europe: in March 2010, the European standardization organization CEN-CENELEC held an informal meeting to discuss the standardization of European smart grid technology. The meeting set up a working group to actively promote the smart grid technology standard research work.

Japan: the ministry of economy, trade and industry (METI) is the main body responsible for the formulation of Japan's industrial and energy policies. In order to advance the research and development of smart grid technology standards, METI established the smart grid technology standardization strategy working group in August 2009. The working group on the standardization strategy of smart grid technology has established 26 areas of limited technical focus, and formulated the international development strategy for technical standards in these areas.

Us: smart grid technology standard system is mainly composed of NIST was affiliated with the U.S. department of commerce official agencies responsible for standardization, aims to build an implementation of the smart grid interoperability technical framework, in this agreement and to coordinate the standard model, in order to realize the interoperability between the device and system.

In April 2009, NIST announced a three-phase plan to develop key standards for smart grids. According to the first phase, the agency has chosen to work with the American electric court to develop a smart grid architecture and a standard roadmap. In January 2010, the agency released the smart grid interoperability standards framework and technology roadmap. Draw the concept of smart grid model, covering power generation, transmission, distribution and utilization, 7 areas, scheduling, marketing and service providers in the existing technical standards identified 25 important standards and 16 need to priority of the standards set. The agency believes that the smart grid should be a priority for standard including eight areas, namely, demand response and energy efficiency, wide area state awareness, electricity, electric vehicles, advanced measurement infrastructure, power distribution network management, information security and network communication.

Future: focus on general needs.
Think smart grid strategy working group, the international electrotechnical commission shall bear the role of research and develop smart-grid technology standards, focusing on those who promote interoperability standards of interface and product standardization; When studying and developing interoperability standards, we should focus on common needs and avoid standardizing some details so as to prevent adverse impacts on innovation and development of technology. Among them, core standards are the key to smart grid technology standards and have a significant impact on the application and solution of smart grid, which is applicable to the main technical fields of smart grid. The five core standards recommended by the smart grid strategy group include open architecture, public information model, substation automation, distribution management and network security.

Definition: smart grid technology standard system.
The smart grid technology standard system consists of 8 professional branches, 26 technical fields, 92 standard series and several specific standards. The system based on the needs of the construction of strong smart grid in China, combined with the smart grid standards and formulation of the progress of the work, in key combing the existing 779 779 international standard and China standard on the basis of the establishment.

The standard for the development of a smart grid key equipment and related industry standards, national standards and international standards, has important guiding role, and promote and stimulate the development of smart grid orderly development and related areas and industries.
