Development prospects of UHV power grid to force cable companies to market opportunitiesApr 21, 2016
17 plenary sessions of the party stated that "Twelve-Five" period to accelerate transformation of the mode of economic development as the main line, which runs through the whole process of economic and social development and in all areas. Energy and electricity is an important material basis for economic and social development. For a long time, Chinese energy distributing relying too much on coal, power balance-oriented development, bringing coal, electricity and transportation stress and serious environmental pollution, shortage of coal down frequently, energy shortages and other problems in the eastern part, become constraints affecting thetransformation of economic development pattern also led to massive loss of power generation enterprises in China, overall development of the difficulties of the power industry. Reverse distribution of energy resources in China and the productivity level is. From basic conditions starting, only speed up construction special high pressure grid, promote big coal electric, and big hydropower, and big nuclear power, and large clean energy base of intensive development, achieved energy resources in more big range of optimization configuration, only can guarantees energy can continued supply, promote energy-saving emissions, from essentially solution economic development in the of energy and power restricted bottleneck, achieved energy and power industry of science development. National grid company as people's livelihood and important source of energy supply, must resolutely implement Central decisions and arrangements, firmly promoting the construction of UHVpower grid, promote transformation of development mode of power and energy,services and promote the transformation of economic development mode.
"Twelve-Five", our projections for new installed capacity of nearly 500 million-kilowatt, end of about 1.44 billion kW; added nearly 2,000,000,001,000 MWh electricity consumption of the whole society, to 6.1 trillion kWh. For energy needs, China will accelerate the construction of coal-electricity base such as Jin-Shan Ning Mengxin, jinsha, Yalong, dadu River basin large hydroelectric plants, as well as Xinjiang, Gansu, Inner Mongolia, Jilin, Hebei, Jiangsu and other qianwanqianwa wind power base. By 2015, more than coal-fired power, utilities, scale of wind turbine delivery will reach 150 million kW, 50 million-kilowatt and 60 million-kilowatt above. These largeenergy bases with Middle Eastern load Center for distance 1000~3000 km and beyond, in particular wind power is intermittent, random power supply, must be implemented by ultra high voltage power grid power of mass, distance delivery and greater scope to dissolve.
From the realities in China and the long term, it is imperative to accelerate the development of ultra high voltage power grid. According to national energy development strategy, based Yu change power development way, and optimization power structure layout, and guarantees power reliable supply, "Twelve-Five" during, national grid planning investment 500 billion yuan, will construction special high pressure transmission line 40,000 km, and variable electric (for flow) capacity 430.001 million v-, to 2015 built "three longitudinal three cross" (East longitudinal: Tin au ~ Nanjing, in the longitudinal: zhangbei ~ Nanchang, West longitudinal: West Inner Mongolia-Changsha; North Cross: in northern Shaanxi-Weifang, in the cross: jingbian-Lianyungang, South cross: ya-Shanghai) Ultra high voltage backbone network and 11 back of uhvdc transmission project, formed a large "West to East" and "North-South transmission" of energy allocation pattern.
Meanwhile, the success of ultra high voltage, also led to the development of UHV technology in the world. At present, India, and Brazil and the United States, and Russia and other countries are actively engaged in research and advance ultra high voltage power transmission, and is actively seeking cooperation with the State grid Corporation. United States Energy Secretary Steven Chu UHV innovation as our United States technology leadership challenges. For the "Twelve-Five" development prospects of UHV power grid, for China's power industry and equipment manufacturers is a rare opportunity for development.
