On November 8, China's independent research, design and construction of the Xiangjiaba-Shanghai ±800 kv UHVDC transmission demonstration project was safe and stable for four months. From 2004 to 2010, China’s UHV power transmissions started from scratch, and they made full breakthroughs by proposing ideas, scientific argumentation, and engineering projects to be completed one after another and playing a role in allocating energy resources across regions.
Jindongnan-Nanyang-Jingmen 1000kv UHV AC pilot demonstration project is the first step of China's UHV. It is independently researched, designed and constructed by China and has completely independent intellectual property rights. The foundation was laid in August 2006 and completed and put into operation on January 6, 2009. It has become the only UHV AC transmission and transformation project that is put into commercial operation in the world today, and is also a symbol of China's construction of modern energy comprehensive transportation system and transformation of energy development methods. Sex works. After more than a year of operation, it has played an important role in relieving tensions in coal and electricity transportation in Central China and achieving mutual benefits in water, electricity, and power grids.
The Xiangjiaba-Shanghai ±800 kV UHVDC transmission demonstration project is the world's largest transmission capacity, the longest distance to power transmission, the most advanced technology, and the highest voltage level of DC transmission projects, with a transmission capacity of 7 million kilowatts. Each year, 35 billion kilowatt-hours of clean hydropower can be delivered to Shanghai, equivalent to 30% of Shanghai's annual electricity consumption.
The UHV project has enabled China to take the lead in realizing the “Created by China†and “Leading by China†in the field of UHV transmission. Relying on UHV technology research and engineering construction practice, China has mastered the core technology of UHV transmission and has become the "leader" of the world's UHV transmission technology. The State Grid Corporation of China has accumulatively applied 679 UHV patents, and has obtained 379 authorizations. It has established UHV AC test bases, DC test bases, high altitude test bases, engineering mechanics test bases, and large-scale power grid simulation and DC complete set design R&D centers. The large-scale grid experimental research system with comprehensive functions and comprehensive indicators ranks among the world's leading standards; China has mastered the core technology of UHV equipment manufacturing, successfully developed the UHV AC full set of equipment and DC key equipment representing the highest level in the world, and created a batch of The world record, the formation of mass production capacity, has promoted China's electrical equipment manufacturing industry into the international advanced ranks.
UHV AC pilot demonstration projects have caused widespread repercussions at home and abroad. The leading comrades of the Party Central Committee and the State Council have successively issued important instructions and fully affirmed them. The International Power Grid Organization called it "great technical achievement" and "an important milestone in the history of the world's power industry." The project also won the title of “100 Classic Classical Projects for the 60th Anniversary of the founding of New Chinaâ€.
