The world's highest altitude UHV transmission project (Gansu section) is fully operational


On the morning of March 12, the pilot ceremony of the first base foundation casting of Qinghai-Henan ±800 kV UHV DC transmission line project (Gansu section) was carried out in Luqu County, Gannan Tibetan Autonomous Prefecture, Gansu Province, which was undertaken by Gansu Power Transmission and Transformation Engineering Co., Ltd. The No. N1312 tower of the Gan 1 section was held grandly, marking the entry into the comprehensive construction stage of the world's highest UHV transmission project (Gansu section).

Qinghai-Henan ±800 kV UHV DC transmission line project starts from Hainan Converter Station in Hainan Prefecture, Qinghai Province, and ends at Zhumadian Converter Station in Zhumadian City, Henan Province, passing through Qinghai, Gansu, Shaanxi and Henan provinces. Kilometers, designed transport capacity of 8,000 megawatts, of which Gansu section is 439.208 kilometers long.

As the general secretary of the internship, Mr. Jin Ping, on the important guiding spirit of the new energy industry base and the idea of ecological civilization construction, the practical actions of implementing clean energy for the benefit of the people. The project is independently powered by the complementary energy of clean energy. It is the first practice in the world to use large DC technology to bundle pure clean energy such as wind, light and water for long-distance delivery. It is also the development of China using UHV transmission technology to promote new A major innovation in the large-scale development and utilization of energy. The project can use the existing and Qinghai network communication lines to send the surplus power of Gansu to the Central China region, which has the functions of ensuring energy security, promoting the clean and transformation of the national energy, stimulating economic growth in Gansu, helping to win the fight against poverty and defending against the blue sky. Very important.

It is understood that the Qinghai-Henan ±800 kV UHV DC transmission line project (Gansu section) is managed by the State Grid Gansu Provincial Electric Power Company, the State Grid Gansu Provincial Electric Power Company Construction Branch on-site control, Gansu Transmission and Transformation Engineering Co., Ltd., etc. 16 The construction, design and supervision units of the home participate in the construction. In order to ensure the standardization of the first base pilot, all participating units strictly implement the requirements of “resource-saving and environment-friendly green harmonious project”, conscientiously implement the 12 supporting policies of the State Grid Corporation, fully implement the standardization management of engineering construction, and vigorously promote Standardized process application, starting from basic work such as manpower, material resources, financial resources, technology, etc., in accordance with engineering risk operation projects and construction difficulties, formulate targeted special construction plans, strictly control safety and quality, and build “safe and reliable, independent innovation” The project of economic rationality, environmental friendliness and world-class engineering has laid a solid foundation for striving for the National Quality Engineering Gold Award.
