During the “Twelfth Five-Year Plan†period, the national grid’s investment in smart grid power grid construction itself and intelligence is 1.5 trillion yuan. Such a large-scale investment will become an opportunity for China’s UHV power grid development. TBEA, Pinggao Electric, Hankow Cable, Dalian Electric Porcelain, etc. are expected to benefit from the advantages they possess in each segment.
During the “12th Five-Year Plan†period, the State Grid will invest approximately 2.55 trillion yuan in power grid construction. Compared with 1.5 trillion yuan during the “Eleventh Five-Year Plan†period, the investment in the “12th Five-Year Plan†has increased by 68% year-on-year. In terms of subdivision, 2.50 trillion will have 500 billion for investment in UHV power grids, 500 billion for investment in distribution networks, and about 1.55 trillion for investment in power grid lines at other voltage levels.
It is understood that during the “12th Five-Year Plan†period, the overall construction phase of the smart grid based on the UHV will create a scale of more than 1.5 trillion yuan. This is only the current expectation and the actual investment in the future may be even worse. This year, the State Grid’s investment in the power grid is nearly 300 billion yuan. Together with the approximately 100 billion yuan investment made by China Southern Power Grid Corporation, the total annual investment will be nearly 400 billion yuan. This large-scale investment will also bring benefits to relevant companies in the industry chain.
Pinggao Electric currently has a production capacity of 1000kV GIS. Localization has established the company's position in the field of switchgear assembly; the state-owned network support attitude is gradually clear, and it will be integrated into a high-voltage switch faucet in the future.

Dalian Electric Porcelain mainly engages in R&D, production and sales of porcelain for high-voltage transmission lines, composite insulators, power station porcelains, composite insulators, and electric porcelain fittings, among which the porcelain insulators and composite insulators account for 68% and 16% respectively. . In terms of production scale, the company is currently the largest manufacturer of disc-suspended porcelain insulators in China, and its sales volume and export volume are ranked first in the industry. In the high-voltage and high-strength insulator market for high-end industries, the company’s 300kN and above insulators won the first place in bids for national power grid bidding, and Japan and NGK have become the only companies capable of producing UHV. Insulator business.
The localization rate of a full set of AC/DC equipment for UHV projects reaches 90%. China has mastered the core technology of UHV equipment manufacturing, and has the capability of mass production of UHV AC/DC equipment. At present, UHV transmission technology has been included in the National Major Medium-and-Long-term Plan for Scientific and Technological Development (2006-2020) and the State Council's Several Opinions on Accelerating the Revitalization of Equipment Manufacturing Industry. By 2020, the national power grid will be fully built into a strong smart grid, forming a "five vertical and six horizontal" UHV backbone grid, real-time power grid status monitoring and intelligent dispatch control, forming an electric car replacement service covering 26 provinces in China. The internet.
At present, on the research and development of smart grid technology, State Grid Corporation has fully mastered the core technologies of UHV and DC transmission, successfully developed a large number of UHV key equipment and components such as large-capacity transformers, and obtained hundreds of patents. However, it is worth noting that smart grids have encountered certain problems in the development process. For example, the cost of new energy such as wind power and solar power generation is still relatively high. At the same time, the standard issue of new energy grid-connected power has yet to be resolved. It may be actively introduced or merged with the aforementioned standards in order to enter a broader market. It is reported that at present, the State Grid has cooperated with Brazil to carry out power grid construction based on UHV transmission.
Intelligentization of UHV transmission is an inevitable choice under the low-carbon economy, and it has great potential for future development.
The transmission of energy in a low-carbon economy is a very critical link, and power transmission is the most important component of energy transmission. The power transmission must not only take into account safety, transmission losses, access to new energy and electricity, maintenance costs, power dispatch optimization, user management and monitoring, but also take into account the long-distance transmission problems caused by unbalanced energy supply and consumption. Traditional high-voltage power transmission methods obviously cannot accomplish such complicated power transmission tasks.
In addition, the grid investment is relatively independent of the macroeconomic environment. Although the current macroeconomic environment is uncertain, the growth of grid investment is more certain. According to the national power grid plan, the UHV power grid will enter the all-round development phase in the “Twelfth Five-Year Plan†period. By 2015, UHV AC and DC will complete investment of 252.3 billion yuan and 261 billion yuan respectively.
In the electric power industry, the technological transformation and upgrading, the gradual transformation of power investment, and the continued rapid development of clean energy are combined to promote the acceleration of China's smart grid upgrading and provide great opportunities for the rapid development of the secondary power equipment industry leading enterprises.
Looking at the current environment, the pace of investment in power equipment has slowed down in 2011, but the smart investment in power grids has not decreased, but has increased. The “Twelfth Five-Year Plan†puts UHV construction in the government’s work report for the first time. This is a major benefit of UHV construction in the next few years. However, this good point is considered to be biased. The key word is that the expression “UHV†has changed from the original “grid†to “transmissionâ€, and the difference between the two words indicates that the future large-capacity transmission between regions will be UHV DC. As the main way.
