“电力王国”，重织经纬

Core Viewpoint - The construction of the Zang-Guangdong DC project has officially begun, marking a significant step in transmitting clean energy from Tibet to the Guangdong region, enhancing energy supply and supporting green development initiatives in China [1][11][20]. Group 1: Project Overview - The Zang-Guangdong DC project is China's first ultra-high voltage project that crosses the Qinghai-Tibet Plateau, Yunnan-Guizhou Plateau, and South China hills, spanning over 2,600 kilometers [1][5]. - The project will consist of over 4,300 towers, with the first segment in Yunnan facing significant geographical challenges, including high altitudes and harsh weather conditions [4][16]. - Once completed, the project is expected to deliver 43 billion kilowatt-hours of clean energy annually, increasing the renewable energy consumption responsibility in Guangdong by 3.8 percentage points [16][18]. Group 2: Technological Innovations - The Zang-Guangdong DC project will set multiple world records, being the strongest, most advanced, and largest investment flexible DC transmission project globally [5][10]. - The project has successfully overcome key technical challenges in areas such as direct current equipment manufacturing, insulation, and electromagnetic environment, achieving breakthroughs in multi-terminal flexible DC fault crossing [10][20]. - Research teams have conducted extensive high-altitude testing to gather critical data for the design and operation of power devices in extreme conditions, ensuring reliability in high-altitude environments [7][8][10]. Group 3: Economic and Environmental Impact - The project aims to optimize the national productivity layout and promote regional coordinated development by facilitating the transfer of clean energy from the resource-rich western regions to economically vibrant areas like the Guangdong-Hong Kong-Macao Greater Bay Area [11][13][20]. - The Zang-Guangdong DC project is expected to play a crucial role in establishing a new energy system in China, supporting the country's dual carbon goals and enhancing energy security [20][21].
