Huainan-Shanghai project approved UHV AC project unfreezing
04-07
On September 28, Shu Yinbiao, deputy general manager of the State Grid Corporation, said that the planned construction of the Huainan-Shanghai UHV AC transmission line has been approved by the National Development and Reform Commission, which means that the UHV AC approval work that has been stagnant for nearly two years has broken the ice. The high-voltage AC power transmission project began to accelerate the pace of development.
It is understood that the 1000 kV Huainan-Shanghai power transmission and transformation project is the first commercial UHV project constructed after the Jindongnan-Nanyang-Jingmen UHV AC test demonstration project successfully passed the trial operation. A power transmission network with large capacity and representing the international level of power transmission and transformation technology.
"The approval of the Huainan-Shanghai power transmission and transformation project is expected. The reverse distribution of energy resources and load centers in my country has promoted the development of UHV power grids. It can be said that the approval of the second AC UHV project means that The strategy of 'power transmission from west to east' has taken another substantial step." Zhang Jianhua, director of the Transmission and Distribution System Research Institute of North China Electric Power University, told the reporter of China Energy News.
UHV will increase trans-provincial power supply.
The "Notice on Printing and Distributing Review Opinions on Supplementary Feasible Research Report of Huainan-Shanghai Power Transmission and Transformation Project" clearly stated that the Huainan-Shanghai power transmission and transformation project passes through Anhui, Zhejiang and Shanghai. Four substations (switching stations) in Huainan, Anhui, Zhebei, and Shanghaixi will be newly built, and 1000 kV lines will be built 2×656 kilometers, with a total static investment of 20.4 billion yuan. Among them, the Huainan UHV station and Wannan switch station will be built in Anhui Province, with a new transformation capacity of 3 million kVA and a line length of 2×457 kilometers. After the completion of the project, the Lianghuai Coal Power Base can add about 7.9 million kilowatts of external power transmission capacity. According to Shu Yinbiao, whether it is line length, investment or transmission capacity, the Huainan-Shanghai UHV AC project is more than twice as large as the Jindongnan-Jingmen demonstration project.
"The approval of the Huainan-Shanghai UHV AC transmission line is mainly to increase the power supply across regions and provinces." Hao Weiping, deputy director of the Electric Power Department of the National Energy Administration, told reporters that the construction of the second UHV line will be conducive to the role of the transmission line. Ensure supply and expand transmission capacity. "This year's inter-regional power transmission has increased by 25% compared with last year. Power grid construction is a very important part of power construction." Hao Weiping said.
Xie Jingdong, Director of the Power Transmission Supervision Department of the East China Electricity Regulatory Bureau, told our reporter that the Huainan-Shanghai power transmission project is different from the Jindongnan-Nanyang-Jingmen UHV AC project. "The Jindongnan UHV AC project is a line of the regional power grid, and the Huainan power transmission and transformation project is a line in the region. In fact, it also has a certain experimental nature." According to Xie Jingdong, East China is ready to start researching
Huainan- Issues related to Shanghai power transmission and transformation project. "We will put the security of the grid first and build in contingencies accordingly."
