0.008 second Gansu Wind Power sent to Xiangtan converter station "UHVDC transmission technology" won the Science and Technology Progress Award

In just 0.008 seconds, clean energy such as wind power and solar power from Gansu can be instantly sent to Xiangtan Converter Station in Hunan. This is the latest success of the UHV ±800kV DC transmission technology won the 2017 National Science and Technology Progress Award Special Award on the 8th. Applied to the scene of ±800kV UHVDC transmission project from Jiuquan to Hunan. UHV ±800kV DC transmission technology is currently the world's highest voltage level, the largest transmission capacity, the longest transmission distance, the most advanced level of technical transmission technology, is to solve the problem of reverse distribution of energy and power load in our country, the implementation of the national "West Power East Send "the core technology of strategy. “China has proposed the development of ultra-high voltage ±800kV DC transmission technology for the first time in the world, with a transmission capacity of 5 to 10 million kilowatts per transmission and a transmission distance of more than 2,000 kilometers. The technical and economic advantages are outstanding, and it is the commanding height of power grid technology.” A complete person, Academician Li Limg, director of the Expert Committee of China Southern Power Grid Company, said. Shu Yinzhuo, Chairman of the State Grid Corporation of China and secretary of the party group, pointed out: “Before UHV, we all built up power plants where we used electricity. This caused tight coal, electricity and oil shipments and brought a lot of pollution. The environment in the eastern region was overburdened. Ultra-high pressure variable coal transmission is used to transmit power, effectively solving the problem of large-scale energy balance." “This is a new peak in the history of energy transportation, which will greatly solve the problem of uneven distribution of energy resources in East and West of China. The improvement of its technology is similar to that from the 'green train' speeding up to the 'Fuxing High Speed ​​Rail', which greatly increases power transmission. Efficiency," said Wang Jifeng, chief engineer of China Southern Power Grid Corporation.
