Introduction: Chinese Federation of electric power enterprises in Beijing recently issued the value of China's first power value white paper "power". According to the white paper display, 2002~2011 years, China's power industry average annual capacity growth rate reached 12.4% of the national installed capacity and power generation respectively from 357000000 kilowatts, 1.65 kwh trillion increased to 1063000000 kW and 4.73 trillion kwh. As of the end of 2011, Chinese grid scale for 3 consecutive years, ranking first in the world.
China Federation of electric power enterprises in Beijing recently issued the value of China's first power value white paper "power". According to the white paper display, 2002~2011 years, China's power industry with an average annual growth rate of electricity generation reached 12.4%. The national electricity installed capacity and power generation capacity of 357000000 kilowatts respectively from 1.65 trillion kwh increased to 1063000000 kW and 4.73 trillion kwh. As of the end of 2011, Chinese grid scale for 3 consecutive years, ranking first in the world.
The rapid development of the electric power industry of large units, EHV, national network new phase change to green power, ultra high voltage, of a smart grid, strong support and promote the growth of national economy. According to the white paper, the power to support the development of the national economy for 30 consecutive years of high-speed growth to an average of nearly. Among them, the 2011 release of "the people's Republic of China National Economic and social development of the Twelfth Five Year Plan" smart grid as a focus of the work of building energy. Power grid enterprises in the fields of intelligent power grid construction planning, implementation of the pilot, the formulation of standards, and the intelligent electric energy meter, large capacity storage battery, the new energy power generation and grid connection control and achieved a number of major technological achievements, so that the development of China's smart grid at the forefront of the world. In 2011, China's line loss rate of 6.37%, down 0.69 percentage points more than in 2005, to continue in the advanced level the same power supply load density conditions of the country. As of the end of 2011, the country has been put into operation for flue gas desulfurization unit capacity reached 630000000 kilowatts, an increase of nearly 11 times more than in 2005. Users in China City 10000 volt power supply system power supply reliability rate of 99.920%, the annual average outage time of 7.01 hours. Rural user power supply reliability rate of 99.790%, average annual power users for 18.43 hours.
The white paper has carried on the forecast to the future intelligent technology achievements to the smart grid represented by the rapid popularization and application in the field of energy. According to the white paper, the basic completion of the smart grid, the power system will push China into the world's largest, the allocation of resources capacity of the strongest, the highest level of intelligent power system, covering the power generation, transmission, substation and dispatching of electricity, power distribution, each link, is of great significance for the adjustment of energy structure, energy saving and emission reduction and climate change. According to the white paper is expected to 2020, China's urban user outage time not exceeding 4 hours / households, rural user outage time not exceeding 17 hours / household.
