首条深入川藏高原腹地的特高压建成投运

Core Viewpoint - The completion and operation of the Jinshang-Hubei ±800 kV UHVDC project is a significant milestone for China's clean energy transition and energy security, facilitating the optimization of energy resources across regions and supporting the country's green low-carbon transformation [1][3]. Group 1: Project Overview - The Jinshang-Hubei project is the first UHVDC project to penetrate the Tibetan Plateau, with a transmission distance of nearly 1900 kilometers and a rated capacity of 8 million kilowatts [3][4]. - The project connects the clean energy resources from the upper reaches of the Jinsha River in Tibet and Sichuan to Hubei, enhancing the power supply and energy security in the region [3][6]. Group 2: Strategic Importance - This project serves as a crucial addition to the "West-to-East Power Transmission" strategy, significantly improving the ability to balance power supply and demand across regions [6][7]. - It supports the high-quality development of the central region and the construction of a new development pattern in China, providing robust power support for national strategies [6][7]. Group 3: Environmental Impact - The project is expected to deliver approximately 40 billion kilowatt-hours of clean electricity annually, replacing about 12 million tons of standard coal and reducing carbon dioxide emissions by around 30 million tons [7][8]. - It promotes the large-scale development and efficient utilization of renewable energy, contributing to the achievement of carbon reduction goals and the construction of an ecological civilization [7][8]. Group 4: Technological Innovations - The project introduces a pioneering site-separated cascading technology for UHVDC, enhancing operational flexibility and marking a significant breakthrough in high-altitude UHV technology [8][10]. - It has developed specialized equipment for high-altitude conditions and successfully implemented rapid circuit breakers that meet extreme environmental requirements, showcasing China's leadership in UHV transmission technology [8][10]. Group 5: Construction Challenges - The project faced significant challenges due to its high-altitude construction environment, including harsh weather, complex geology, and logistical difficulties [10][11]. - A comprehensive safety and ecological protection system was established to address these challenges, achieving a record of zero accidents during construction [10][11].
