从2004年开始,我国仅用4年时间,建成了目前世界上运行电压最高、技术水平最先进、拥有自主知识产权的交流输电工程——1 000 kV晋东南—南阳—荆门特高压交流试验示范工程,并于2010年8月12日通过国家验收,标志着我国在远距离、大容量、低损耗的特高压输电核心技术和设备国产化上取得重大突破,进入了特高压交直流混合电网运行时代。与500 kV超高压电网相比,特高压电网可以解决我国现有电网输送能力不足的问题,有助于提高输电效率、降低线路损耗、减少投资成本、节约土地资源。
Since 2004, China has completed the AC transmission project of 1 000 kV Jindongnan-Nanyang-Jingmen UHV AC Power Transmission Project with the highest operating voltage, the most advanced technology and independent intellectual property right in only 4 years. Project, and passed the national acceptance on August 12, 2010, marking a major breakthrough made by China in the localization of UHV power transmission core technologies and equipment for long distance, large capacity and low loss, and entered the UHV AC / DC hybrid power grid operation era. Compared with the 500 kV EHV power grid, the UHV power grid can solve the problem of insufficient transmission capacity of the existing power grid in our country, contribute to improving transmission efficiency, reducing line losses, reducing investment costs and saving land resources.
