摘要
特高压交流输电是指1 000 kV及以上电压等级的交流输电,具有输送容量大、距离远、损耗低、占地省等显著优势,是一种资源节约型和环境友好型的先进输电技术。结合晋东南—南阳—荆门特高压交流试验示范工程,系统介绍了中国在发展特高压交流输电方面的主要技术创新,重点包括电压控制、潜供电流控制、外绝缘配合、电磁环境控制、试验技术、成套设备、系统集成、调试运行等方面。推广应用这些新技术对于加快特高压电网发展有帮助作用。
UHV AC transmission refers to the alternating current transmission at voltage of 1000 kV and above. It is a kind of resource saving, environmental friendly aild advanced transmission technology, which has the advantages for power transmission of large capacity, long distance, low power loss, less land occupation, etc. Based on Jindongnan-Nanyang- Jingmen 1000 kV AC demonstrating project, this paper present the innovation of UHV AC transmission technology in China, which focus on voltage control, secondary-arc current mitigation, external insulation coordination, electromagnetic environment control, experimental technique, development of UHV equipment, system integration, commissioning＇ and operation of UHV AC project etc. It＇s very helpful for development of UHV grid by promotion and application of this new technology.
