新华鲜报｜电力“天路”贯通！西藏首个特高压工程投运

Core Viewpoint - The successful commissioning of the Jinshang-Hubei ±800 kV UHVDC transmission project marks the beginning of a new era for the large-scale delivery of clean energy from Tibet, enhancing the region's energy export capabilities and contributing significantly to environmental benefits [1][5][6]. Group 1: Project Overview - The project officially commenced operations on December 18, with the Kamei converter station completing a 168-hour trial run [1]. - The Kamei converter station, located at an altitude of approximately 3720 meters, is the highest UHV converter station in the world [3]. - The total investment for the Jinshang-Hubei project is approximately 34.3 billion yuan, with a rated voltage of ±800 kV and a capacity of 8 million kW [5]. Group 2: Technical Innovations - The project employs the first domestic "site-level cascading" UHVDC technology to address challenges in high-altitude environments [5]. - Innovations include systematic enhancements to insulation distances to cope with the thin air at high altitudes, which affects the insulation performance of key equipment [5]. Group 3: Environmental and Economic Impact - The design annual electricity transmission capacity is 40 billion kWh, which is expected to replace approximately 12 million tons of coal annually and reduce carbon dioxide emissions by about 30 million tons [5]. - The project has created over 3000 auxiliary and service jobs annually for local farmers and herdsmen, contributing to an income increase of 425 million yuan over five years [6]. Group 4: Operational Efficiency - The Kamei converter station is equipped with over 2000 cameras and automated inspection robots to enhance operational efficiency and reduce the workload on staff [8]. - The project integrates Tibet more deeply into the national energy framework, supporting the optimization of the national energy structure and aiding in achieving carbon neutrality goals [8].
