国网官宣：首条深入川藏腹地特高压工程投运

Core Viewpoint - The State Grid announced the successful commissioning of the Jinshang-Hubei ±800 kV UHVDC transmission project, marking a significant advancement in clean energy transmission and enhancing national energy security [1][2]. Group 1: Project Overview - The Jinshang-Hubei project is the first UHVDC transmission project to penetrate the Tibetan Plateau, facilitating the cross-regional optimization of clean energy [1]. - The project spans approximately 1900 kilometers, starting from the upper reaches of the Jinsha River and passing through Tibet, Sichuan, Chongqing, and Hubei [1]. - It utilizes ±800 kV rated voltage and an 8 million kW rated capacity, featuring a dual converter station setup to enhance operational flexibility [1]. Group 2: Environmental Impact - The project is expected to deliver approximately 40 billion kWh of clean electricity annually, equivalent to replacing about 12 million tons of standard coal and reducing carbon dioxide emissions by around 30 million tons [2]. - It will promote the large-scale development of integrated water, wind, and solar energy bases in the upper reaches of the Jinsha River, optimizing the energy structure at the sending end [2]. Group 3: Infrastructure and Capacity - The State Grid has completed a total of 42 UHV projects, achieving a cross-regional transmission capacity of 370 million kW [2]. - The project contributes to the formation of a robust UHVAC backbone network across East, North, Central, and Southwest China, integrating advanced dispatch control systems and electricity market trading platforms [2].
