9毫秒闪送！藏粤直流输电工程启动建设

Core Points - The construction of the Zang-Guangdong DC project, a key cross-provincial power transmission project under China's 14th Five-Year Plan, has commenced, marking it as the world's most powerful, technologically advanced, and largest investment flexible DC transmission project [1][3] Group 1 - The Zang-Guangdong DC project starts in Tibet, passing through Yunnan and Guangxi, and ultimately reaching Guangdong, with a total transmission line length of approximately 2,681 kilometers [3] - Upon full operation in 2029, the project is expected to deliver over 43 billion kilowatt-hours of electricity annually to the Guangdong-Hong Kong-Macao Greater Bay Area, which is equivalent to half of the annual output of the Three Gorges Power Station, and will be 100% clean energy [3] - The project will feature four converter stations located in Changdu and Linzhi in Tibet, as well as in Guangzhou and Shenzhen in Guangdong [3] Group 2 - The clean energy base in southeastern Tibet has a new energy installed capacity of 10 million kilowatts, serving as the starting point for the Zang-Guangdong DC project [3] - The project faces significant challenges due to its long distance of over 2,600 kilometers and the need to traverse complex geographical terrains, including high mountains with altitudes reaching 5,300 meters and the geologically complex Hengduan Mountains, with nearly 90% of the route being mountainous [3] - To address the instability of new energy generation, the project employs world-leading "ultra-high voltage multi-terminal flexible DC transmission" technology, which allows for flexible scheduling of green electricity generated at different times and locations, minimizing current disturbances and impacts on the power grid, ensuring uninterrupted power supply [3] - The entire transmission process from Tibet to Guangdong takes only 9 milliseconds [3]
