The “four UHV and smart grid standards” formulated by the State Grid will likely become international standards

Recently, the first working group meeting of the Institute of Electrical and Electronic Engineers (IEEE) was held. The meeting discussed and considered the four UHV and smart grid standards formulated by the State Grid Corporation of China, and was finally approved to establish a project working group.

In this regard, industry insiders believe that if the above standard technology system matures and is internationally recognized, the standard will become an international standard, which means that for the first time, the smart grid construction will “stand on the same starting line” with other countries in the world. .

Why do we need standard guidelines for building speedups? Why does the smart grid technology standard system need to be discussed at the conference? “This may be related to the rapid development trend of smart grids.” An electric power equipment supplier in Beijing told reporters that the State Grid Corporation has already smelled smart Because of the development opportunities of the power grid, it is eager to formulate relevant standards to regulate it.

In fact, the development of smart grids is an objective necessity. At present, China’s traditional energy sources are increasingly in short supply, consume large quantities, and have serious pollution. However, nuclear power technologies that were once favored have been suspended due to the nuclear leakage in Japan. However, China’s trend toward electricity demand during the “12th Five-Year Plan” period cannot be avoided.

According to the latest annual energy statistics released by BP, US power generation in 2009 was 4.1496 trillion kWh, down 3.8%, accounting for 20.7% of the world, while China’s power generation was 3.7251 trillion kWh, up 6.9% year-on-year, accounting for 18.5% of the world. In 2009, China’s power generation was equivalent to 89.77% of the United States, compared with 75.18% in 2007, 33.97% in 2000, and 19.50% in 1990. Some market participants expect that this figure will be close to 100% in 2010, and in 2011 no accident will be greater than 100%. Therefore, the development of UHV and smart grids is the top priority for the development of the 12th Five-Year Plan.

The State Grid Corporation of China also clearly stated at its 2011 work conference that China will invest more than 500 billion yuan in the next five years to build a "three vertical and three horizontal" UHV AC backbone grid and 11 UHV DC transmission projects. The total length of high-voltage transmission lines will reach 40,000 kilometers, forming a strong grid of AC-DC coordinated development.

People in the industry believe that in the 12th five-year opening year, for the electrical industry, the power grid construction will become the focus of power investment in 2011, and the related smart grid construction, rural power grid renovation, and construction of UHV power grids will also encounter rapid Great opportunities for development.

It is understood that relevant power equipment suppliers and local power companies have begun to increase the market development efforts of the “smart grid”. In 2011, Guodian NARI Company continued to benefit from smart grid construction, and dispatch automation and power equipment such as electricity meters and acquisitions grew rapidly. The company’s technological leadership in the field of software control is expected to continue to enable the company to win the charge and discharge stations and energy-saving total of electric vehicles. Package engineering and other large orders.

Sichuan Provincial Electric Power Company of State Grid recently announced that in the second half of this year, the province will carry out provincial-level smart grid dispatch support system and electric vehicle charging and replacement facilities. The construction of seven charging stations and 480 charging piles will be completed in the country during the year. Took the lead in building the main monitoring station for electric vehicle charging facilities.

"The formulation of a technical standard system will specify the direction of business development for electric equipment suppliers and local electric power companies. We also expect that such a standard will be introduced as soon as possible. Otherwise, the introduction of equipment and the introduction of standards will result in waste of resources." The above-mentioned electric equipment supplier says.

Equipment safety urgently requires technical support In fact, the reporter found during the interview that the State Grid Corporation rushed to the technical standard system of the smart grid, mainly due to the consideration of smart grid equipment safety. According to industry sources, the State Grid will invest more than 4 trillion yuan in the next 10 years to promote the construction of a strong smart grid, and 15% of the total investment will be used for construction related to equipment safety.

It is understood that the definition of a strong smart grid in China is based on the UHV grid as the backbone grid and the strong grid of coordinated development of all levels of power grids. It is supported by a communications information platform and is characterized by information, automation, and interaction. The power system's power generation, transmission, substation, distribution, power supply, and dispatching processes cover all voltage levels and realize a highly integrated, modern power grid with "power flow, information flow, and service flow."

From this perspective, smart grid equipment manufacturing is an important support for the deep integration and development of information technology and high-end equipment manufacturing. It is also an important content of high-end equipment manufacturing. The security of equipment in all aspects is related to the safety of the entire smart grid.

It is understood that IOActive researchers used a joint network attack in 2009 to remotely infiltrate and control smart meters. They can take over a piece of equipment, display a message on the LCD screen, and spread the attack from the electricity meter to the electricity meter. "Although these researchers did not cause any damage, this experiment shows that many devices currently deployed to support smart grid projects - smart meters, sensors, etc., have the risk of attacking the grid." Indicated.

The industry believes that the safety of equipment has become an important basis for the safe and stable operation of smart grids and reliable power supply to the society, and is an important part of the production, operation and management of electric power companies. The security of equipment requires a variety of information security methods such as special Trojan defense systems and cryptographic technologies to cooperate with and supplement the relevant electrical equipment of the smart grid, and to maximize the use value.

At present, China's relevant smart grid security standards development, technology research and industry promotion are actively underway.
