According to the UHV construction plan disclosed by the State Grid Corporation on the same day, by 2015, the “Three China†(North China, East China, Central China) UHV power grids will be built to form a “three vertical and three horizontal one ring network†and will be built 11 Back to UHVDC transmission project. According to this plan, UHV investment in the next five years will reach 270 billion yuan.
The “three vertical and three horizontal and one ring network†of the State Grid Corporation’s “12th Five-Year Plan†for ultra high voltage refers to three vertical UHV AC passageways from the Ximeng, Mengxi, Zhangbei and Northern Shaanxi energy bases. China’s “transmission of electricityâ€, northern coal-fired power, and southwest hydropower were transmitted to the North China, Central China, and Yangtze River Delta UHV ring networks via three horizontal UHV AC channels. Among them, "three verticals" are Ximeng-Nanjing, Zhangbei-Nanchang, and Shanbei-Changsha; "Sanheng" is the three horizontal transmission channels of Mengxi-Weifang, Jinzhong-Xuzhou, and Ya'an-Fujian; "It is the Huai'nan-Nanjing-Taizhou-Suzhou-Shanghai-Zhebei-Weinan-Huainan Yangtze River Delta UHV double loop network. In the UHV DC project, during the “Twelfth Five-Year Plan†period, it will cooperate with Southwest Hydro, Northwest China’s coal and wind power base development, and construct the Jinping-Jiangsu II return UHV DC transmission project to complete the Qinghai-Tibet DC interconnection project to meet Tibet. Power supply to achieve the networking of Tibet's power grid and the main northwest network.
The goal of China Power Grid Corporation is to build a "Sanhua" UHV synchronous power grid as the center by 2020, with the Northeast UHV power grid and the Northwest 750kV power grid as the sending end, linking major coal and electricity bases, large hydropower bases, and large nuclear power bases. Large renewable energy bases, strong grids with coordinated development of all levels of power grids.
