Traveling thousands of kilometers, a single line becomes an electric road across the moat. With continuous breakthroughs in original technology, China's UHV technology is at the forefront of the world and bravely climbs the world's "high" peak.
Combined with the mainland's resource endowment, UHV transmission technology is of great significance to the mainland's energy transmission.
In the initial stage of the development of UHVDC transmission technology in the mainland, some problems were also encountered. After more than 20 years of scientific and technological research and continuous exploration, China's UHV technology has now been at the forefront of the world.
Lu Yu, director of the flexible transmission department of the NARI Jibao Research Institute under the State Grid NARI Group, introduced, "At present, most of the world's UHVDC projects are implemented by our country, and the UHVDC projects with the highest difficulty and the highest technical level are also developed and completed by our country. ”
Silver line flying frame, crisscrossing China. By the end of 2023, a total of 19 UHV AC lines and 20 UHVDC lines have been built in mainland China. The transmission length of the UHV line is more than 40,000 kilometers, and the total transmission capacity has exceeded 3 trillion kilowatt hours since its completion.
