National Grid Demonstration Project UHV review the preliminary work - power

, high voltage, AC - electric industry

State Grid Corporation in the government-led, business promotion, special high-voltage power grid construction has taken a firm step through the scientific decision-making in technology, equipment manufacturing and achieved a major breakthrough in Southeast Shanxi - Nanyang - Jingmen UHV Demonstration Project to complete the approval process, China's first commercial operation of the special high-voltage transmission line is about to start.

UHV 1000 kV AC power grid is, positive and negative DC voltage of 800 kV and above transmission network. Construction of UHV grid will greatly enhance the long-distance, large capacity transmission efficiency, reduce transmission losses, lower transmission costs, large coal bases, fire power base, a large nuclear power base construction, a wider range of resources to achieve optimal allocation, promoting China energy efficient development and use, and promote economic and social sustainable development. UHV power transmission technology is the development direction of the world's power grid, the development of UHV power grid is to implement the objective requirements of the national energy strategy. State Grid Corporation standing in the forefront of the development of world power, China's national conditions and development of the law of power, with a high sense of responsibility and dedication, to face challenges and difficulties to build a special high-voltage power grid comprehensive focus on the development of strong coordination at all levels of power National Grid.

Scientific decision-making in order to speed up the construction of UHV-focused national grid

With a series of 500 kV AC and DC 750 kV Power Transmission Project and demonstration projects continue to accumulate practical experience, with the worldwide research of UHV transmission technology continued to deepen, as the clear market demand characteristics and conservation of resources increasingly clear, the State Grid Corporation of the party and the party stood on the overall situation of national development, with a high sense of political responsibility and to think and plan development of the national grid. December 27, 2005, State Grid Corporation of the Party Group held an enlarged meeting that "social and economic development and a strong market demand, calling for the emergence of ultra high voltage grid."

State Grid Corporation of active work, to the party and government reporting. In 2005, Chinese Vice Premier Zeng Liu Zhenya, general manager of listening to the report, delivered an important speech that the construction of UHV power grid is the power industry to implement the scientific concept of development of major initiatives, the state of energy an important means of macroeconomic control is to optimal allocation of energy resources to achieve effective way; the development of UHV power network can promote our technology innovation and technological upgrading of electrical manufacturing industry, both for China and for the world, is a great initiative and important contribution, as set out milestones history into the electric power industry development.

Development of UHV power transmission technology has government support, the community has reached broad consensus. R UHV transmission technology and equipment included in the "Long-term Scientific and Technological Development Plan (2006 to 2020)" (Guo Fa [2005] No. 44); UHV power transmission equipment to carry out the development to include " speed up the revitalization of the State Council on Several Opinions of the equipment manufacturing industry "(Guo Fa [2006] 8); UHV construction included in the State Department," the work of energy points the next two years "(Guo Ban Fa [2005] 35). After optimization of a large number of in-depth and extensive than the democratic election facts from the State Grid Corporation proposed building Jindongnan ~ ~ Jingmen UHV Nanyang Demonstration Project proposals.

2006 4 The State Council leaders agreed to a National Development and Reform Commission submitted to the State Council on the development of UHV power transmission technology in China the situation and consult the views. June 2006 13 ~ 14, the National Development and Reform Commission has organized the development of UHV power transmission equipment working meeting of the deployment of research and development of the UHV equipment, construction of concrete work. June 20, 2006, the National Development and Reform Commission issued "the General Office of the State Development and Reform Commission to conduct exchanges on the 1000 kV, 800 kV DC power transmission test, notification of the preliminary work demonstration project" (Office of Energy Development and Reform [ 2006] No. 1264).

State Grid Corporation launched the project in the approved work, UHV preliminary evaluation of pilot projects, feasibility studies, key technology research, external consulting, engineering design, equipment procurement, construction management, construction targets, and have started work to technology, equipment manufacturing as the main content of the preparatory work is particularly full.

Innovation efforts to master the key technology of UHV

Technology is the driving force for enterprise development, innovation is a source of scientific and technological progress. State Grid Corporation follows the "independent innovation, focusing on leaps and bounds to lead the future" approach, give full play to enterprises in independent innovation in the main role in the process of building special high-voltage power grid to master core and key technologies.
