据国家电网有限公司(以下简称"国家电网")发布的消息，12月18日，我国首个深入川藏高原腹地的特高 压工程——国家电网金上到湖北正负800千伏特高压直流输电工程建成投运。国家电网年内累计建成投 运4条特高压直流工程。 国电南瑞（600406）科技股份有限公司通过持续的研发创新，保持行业领先地位。该公司相关负责人在 上证e互动平台公开表示："在高压领域，公司重点突破特高压柔性直流输电所需的高耐压器件，着力解 决多芯片并联时的电流均衡难题，相关技术已开始支撑正负800千伏特高压工程建设。" 苏商银行特约研究员付一夫在接受《证券日报》记者采访时表示："特高压工程具有重要的战略意义， 它能够实现全国范围内清洁能源优化配置，推动能源结构绿色低碳转型。" 特高压工程持续推进 据悉，金上到湖北正负800千伏特高压直流输电工程总投资334亿元，起于金沙江上游，止于湖北黄石大 冶换流站，输电距离近1900公里。国网湖北电力特高压工程建设管理办公室副主任吴子良在接受媒体采 访时表示，工程投运后，每年输电能力相当于湖北省全年用电量的六分之一。不仅能大幅提升湖北区外 受电的清洁化比例，还能增强电力余缺互济、时空互补能力，助力湖北实现 ...

Core Viewpoint - The Ningxia-Hunan ±800 kV UHVDC transmission project has been officially put into operation, marking a significant advancement in China's energy infrastructure, particularly in renewable energy transmission [1][2]. Group 1: Project Overview - The Ningxia-Hunan project spans 1616 kilometers, connecting key energy regions and is the first UHVDC line approved primarily for transmitting renewable energy from the "Shagouhuan" wind and solar power base [2]. - The project has a total investment of 28.1 billion yuan and is the third UHVDC project to be commissioned in China this year [1]. Group 2: Renewable Energy Focus - Over 70% of the installed capacity for the project is from renewable sources, setting a new record for similar projects. The total power capacity is 17.64 million kW, with 13 million kW coming from renewable energy, including 4 million kW from wind and 9 million kW from solar [2]. - The project is expected to deliver over 36 billion kWh of electricity annually to Hunan, with more than 50% of this coming from renewable sources [2]. Group 3: Economic and Infrastructure Impact - The project will increase Hunan's electricity supply by approximately one-sixth, enhancing the province's external power receiving capacity to 16 million kW [2]. - The investment in the project is projected to stimulate over 70 billion yuan in local investments in Ningxia, positively impacting infrastructure development and related industries [3]. Group 4: Technological Innovations - The project has developed a series of standardized results in UHVDC technology, including over 5,500 typical drawings and the establishment of various national and industry standards [3]. - All equipment for the project has been domestically manufactured, achieving successful initial operation and stable performance, marking a significant step in strengthening China's power transmission and transformation industry [3].
