Recently, from the 2013 International Smart Grid Forum news came up, China has fully mastered UHV AC and HVDC core technology and manufacturing equipment package, in the control of large power grids, smart grid, clean energy access grid and other fields to obtain a Approved world-class innovation achievements. At present, it has established a systematic standard system for UHV and smart grid technologies and has compiled 19 related international standards. China's UHV transmission technology is at the leading position in the world with complete independent intellectual property rights and is designated as International standard voltage, will be promoted to the world. We all know that China's national conditions are that the distribution of energy resources and the demand for energy are reversed. Our country's energy resources are mainly distributed in the north and northwest, but the most power-consuming is in the southeast, which requires the energy resources in place Transform into electricity, long-distance transport, in the country to optimize the configuration. The UHV power transmission has the advantages of long distance, large capacity, low loss and high efficiency. The construction of a strong smart grid with a UHV power grid as the backbone network can promote large coal-fired power plants, large hydropower plants, large nuclear power plants, large renewable energy bases Intensive development and utilization. At the same time, UHV power grids can enhance the ability of the power grid to withstand unexpected events and serious faults, further improve the reliability and stability of power system operation, and make the strong smart grid construction have a solid grid foundation. Therefore, it is necessary to develop UHV. Since 2009, China proposed the construction of a UHV power grid as its backbone, connecting large-scale energy bases and major load centers. It has built two 1000 kV AC transmission lines and four 800 kV DC transmission lines with the world's highest voltage levels. These backbone grids can transform energy in western China, especially solar energy and wind energy, into long-distance power load to the eastern electricity load center. According to the operation situation, over the years, they have endured thunderstorms, rain, snow, ice and lightning Harsh natural conditions and various modes of operation test, safety, environment, economy and other indicators meet and exceed the design standards and requirements. Looking to the future, China is developing 1,100 kV DC technology and equipment, this technology will achieve greater transmission capacity, up to 13,750,000 kilowatts; farther economic transmission distance up to 5,000 km, will build cross-regional and transnational , Transcontinental transmission channel to create conditions. In order to build North China - East China - Central China UHV synchronous grid as the focus, and strive to build a "five vertical and five horizontal" UHV grid and 27 UHV DC project by 2020, with 450 million kilowatts of power a wide range of configuration capabilities to meet the 550 million The demand for clean energy delivery and consumption in kilowatts. Today's world-class enterprises to do the standard, only to improve the leading technical standards for the lead, enterprise development can be invincible. UHV technology allows us to change from "follower" to "leader" to enhance the power grid's ability to deploy a wide range of energy sources so as to better guarantee the country's energy supply and energy security and meet the needs of rapid economic and social development.
