National Development and Reform Commission approves the transmission of electric power from east to west for UHV AC project

On September 28, 2011, Shu Yinhao, Deputy General Manager of the State Grid Corporation of China, stated at the 2011 Smart Grid International Forum media meeting that the National Development and Reform Commission had approved the UHV AC project from Jidong to Dongfang, marking the entry of the UHV AC project. Speed ​​up the start-up phase. As the second AC UHV power transmission project, the project is twice as large as the previous AC UHV project in terms of line length, investment and financing, or transmission capacity.
Shu Yinzhe pointed out that the development of UHV has been included in the national "Twelfth Five-Year Plan" development outline. After the successful UHV AC/DC demonstration project, UHV should develop rapidly during the "Twelfth Five-Year Plan" period. There is no doubt about this. of. Since the beginning of this year, the UHV DC project has also shown a trend of accelerating development, and it is confident that during the “Twelfth Five-Year Plan” period, a “three vertical and three horizontal” UHV backbone grid will be formed. However, he also stated frankly that, as for difficulties, it will certainly face the issues of tight schedule and project construction due to the acceleration of development, as well as the structural adjustment and layout optimization of power supply.

Shuyin Yin disclosed that China and Brazil have always had exchanges in the field of energy and electricity. China’s UHV transmission technology is fully applicable to Brazil’s large-scale and long-distance transmission of hydropower demand in the Amazon.
At the media meeting that day, the secretary general of the Institute of Electrical and Electronics Engineers (IEEE) Secretary James Plandergarst responded to a Xinhua reporter’s question and said that in terms of UHV technology, the State Grid Corporation of China is unique in the world. Is the leading one.

According to the national power grid plan, by 2020, the UHV backbone network will be built around the "Sanhua" (North China, Central China and East China) regions, connecting China's major regional power grids and major load centers. As a result, during the "Twelfth Five-Year Plan" period, the UHV AC line in the "Three Chinas" area will be built into a "three vertical and three horizontal and one ring network". The total UHV AC and DC investment is about 530 billion, of which DC investment is about 270 billion, and exchange investment is about 260 billion. The total investment is more than 25 times more than the 20 billion during the "Eleventh Five-Year" period.
According to sources close to the State Grid, another exchange of ultra-high voltage engineering Tin Meng to Nanjing transmission line will be obtained next month by the National Development and Reform Commission. At the same time, it is expected that 7 UHV AC/DC lines will be approved this year.
