9月16日，我国"十四五"规划建设的跨省区输电重点工程——藏粤直流工程启动建设。这条能源"超级大动脉"，将如何把"绿电"从西藏送到广东？ 世界最强！2681公里的"电力天路" 藏粤直流工程，即藏东南至粤港澳大湾区±800千伏特高压直流输电工程。 它以西藏为起点，途经云南、广西，最后到达广东，输电线路全长约2681公里，额定输电容量1000万千瓦。其中，将在送端西藏昌都、林芝，以及受端广东 广州、深圳共建设四座换流站。 四座换流站效果图 根据规划，2029年全面投运后，藏东南清洁能源基地每年可向粤港澳大湾区负荷中心输送超430亿千瓦时电能，相当于三峡电站年发电量的一半。并且100% 为清洁能源，可替代标煤消耗约1200万吨，减少二氧化碳排放约3300万吨。 这也是我国首个跨过青藏高原、云贵高原和华南丘陵三级地理阶梯的特高压工程。其中，有海拔高达5300米的高山、地质复杂的横断山脉，全线近90%为山 地、30%为高山大岭。直流输电线路横跨雪域高原、横断山脉、三江并流区域，穿越高寒冻土、地震断裂带、37公里无人区等恶劣环境。 作为目前世界上输电能力最强、技术水平最先进、投资规模最大的柔性直流输电工程，藏粤直流工程总 ...

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]

Core Viewpoint - The construction of the Zang-Guangdong DC project, the world's most powerful and advanced flexible DC transmission project, has commenced, aiming to enhance clean energy transmission from Tibet to the Guangdong-Hong Kong-Macao Greater Bay Area [1] Group 1: Project Overview - The Zang-Guangdong DC project starts in Tibet and spans approximately 2,681 kilometers through Yunnan and Guangxi, ending in Guangdong [1] - The project will include four converter stations located in Changdu and Linzhi in Tibet, as well as Guangzhou and Shenzhen in Guangdong [1] - Upon full operation in 2029, the project is expected to deliver over 43 billion kilowatt-hours of electricity annually to the Greater Bay Area, equivalent to half of the annual output of the Three Gorges Dam, with 100% being clean energy [1] Group 2: Technical Challenges and Solutions - The project faces significant challenges due to its geographical route, which includes traversing the Qinghai-Tibet Plateau, Yunnan-Guizhou Plateau, and South China hills, with nearly 90% of the route being mountainous terrain [1] - The instability of renewable energy generation presents additional challenges for the construction of the Zang-Guangdong project [1] - To ensure the smooth delivery of green electricity to Guangdong, 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 [1] - The technology enables the transmission of green electricity from Tibet to Guangdong in just 9 milliseconds [1]

Core Viewpoint - The construction of the Zang-Guangdong DC project, the world's most powerful and advanced flexible DC transmission project, has commenced, representing a significant investment in China's energy infrastructure [1][5]. Group 1: Project Overview - The Zang-Guangdong DC project starts in Tibet and spans approximately 2,681 kilometers through Yunnan and Guangxi, ending in Guangdong, with four converter stations being built in key locations [3][5]. - The project utilizes domestically developed, internationally leading ultra-high voltage flexible DC transmission technology, with a rated voltage of ±800 kV and a capacity of 10 million kW, involving a total investment of 53.2 billion yuan [5]. Group 2: Economic and Environmental Impact - The project is expected to facilitate the conversion of Tibet's resource advantages into economic benefits, addressing challenges related to high-altitude DC transmission and the integration of renewable energy in weak grid areas [7]. - Upon full operation in 2029, the project will deliver over 43 billion kWh of clean energy annually to the Guangdong-Hong Kong-Macao Greater Bay Area, equivalent to half the annual output of the Three Gorges Dam, with 100% of the energy being clean [7][14]. Group 3: Technical Challenges and Solutions - The project faces significant challenges due to the geographical terrain, including high mountains and complex geology, with nearly 90% of the route being mountainous [10]. - To ensure stable delivery of green electricity, the project employs advanced "ultra-high voltage multi-terminal flexible DC transmission" technology, allowing for flexible scheduling of renewable energy and minimizing disturbances to the grid [11].
