On March 25th, "World's No. 1 UHV" - ±1100 kV Xinjiang Zhundong Changji to Anhui Weinan Guquan UHV DC transmission line terminal converter station, the world's highest voltage level converter station first transformer successfully delivered The construction site marks the entry of the project construction into the main electrical equipment installation phase. It provides basic support and important guarantee for the completion and commissioning of the entire transmission line during the year.
The ±1100 kV Changji-Guquan UHV DC project is an important milestone in China's UHV transmission project. It has set a new height in the world's power grid technology. It is currently the world's highest voltage level, the largest transmission capacity, the longest transmission distance, and the highest level of technology. The world's first) UHV DC transmission project. Passing through Xinjiang, Gansu, Ningxia, Shaanxi, Henan and Anhui provinces, newly built two 1,100 kV converter stations in Changji and Guquan, with a new commutation capacity of 24 million kilowatts; new Zhundong to Weinan ±1100 kV DC line 3,324 kilometers; total investment in engineering dynamics is 40.7 billion yuan.
China is the only country in the world that masters and applies UHV's cutting-edge technology. It demonstrates China's creation in the global power industry, China's intellectual creation, China's standards, China's leading role, and China's exemplary image. Internal interconnection, intercontinental interconnection, and building a global energy Internet have opened a new era in the development of UHV transmission technology.
