  • Detail

China's smart power technology ranks among the world's top.

the China Electricity Council recently released China's first white paper on the value of electricity in the power industry in Beijing. The book describes the history of electricity with the rejuvenation of the Chinese nation, and shows the extraordinary value that electricity, as the strongest backing for China's rapid economic growth, has created for society and a bright future

the white paper, in easy to understand language, with simple cartoons, starts with cognition, action and outlook, and in time order, expounds the three aspects of power changing the world, power creating value, and power holding hands with the future, so as to make the history of power development vivid and deep into the hearts of people, and also make the value of power civilization and production jump on the paper

power changes the world

the chapter of power cognition reproduces the development process of power industry and is the epitome of the history of national economic development

from large generating units, ultra-high voltage and nationwide connection to a new stage of development of green power generation, ultra-high voltage and intelligent electricity

the white paper shows that from 2002 to 2011, the average annual growth rate of power generation in the power industry reached 12.4%. The installed capacity and power generation capacity of the country have increased from 357 million KW and 1.65 trillion kwh to 1.063 billion kw and 4.73 trillion kwh respectively, and the focus of the company's development is also shifting to the West. By the end of 2011, the scale of China's electricity industry had ranked first in the world for three consecutive years. The circuit length of 220 kV and above transmission lines is 475000 kilometers, and the public variable capacitance of 220 kV and above is 2.208 billion kVA. With the continuous improvement of the highest transmission voltage level, 750 kV transmission lines and 1000 kV high-voltage AC and 800 kV high-voltage DC transmission lines have been built successively due to the deterioration of performance. AC and DC interconnection has been realized for all provincial-level electricity, and a national connection pattern has been formed. The rapid development of the electric power industry has fundamentally lifted the bottleneck restriction of electric power on the development of the national economy, effectively supported and promoted the growth of the national economy, and basically met the growing demand of people's living standards for electric power growth

power creates value

the chapter of power action shows the important role of the power industry in ensuring the security of energy strategy through the vivid description of the power development supporting the national economy for more than 30 years, with an average of nearly 10% high-speed growth

in China's railway transportation volume, coal transportation is also a research topic at the level of technology combination and utilization, accounting for about 50%, mainly electric coal. It is one of the strategic choices to optimize and adjust China's energy structure and layout to adhere to the simultaneous development of coal transportation and power transmission, vigorously accelerate the development of power transmission, build UHV power, and improve the large-scale and long-distance power transmission capacity while continuing to strengthen the construction of Railways and other transportation

according to the white paper, the 12th Five Year Plan for national economic and social development of the people's Republic of China, released in March 2011, takes smart electricity as one of the key tasks of energy construction. Power enterprises have formulated plans, implemented pilot projects, formulated standards in the construction of smart electricity, and made a number of major technological achievements in smart electricity meters, high-capacity energy storage batteries, new energy power generation and parallel control, making China's development of smart electricity in the forefront of the world. In 2011, China's line loss rate was 6.37%, down 0.69 percentage points from 2005, and continues to rank at the advanced level of countries with the same power supply load density. By the end of 2011, the capacity of flue gas desulfurization units in operation nationwide had reached 630 million KW, an increase of nearly 11 times over 2005

the power supply reliability rate of users of China's urban 10kV power supply system is 99.920%, and the annual average outage time is 7.01 hours. The power supply reliability of rural users is 99.790%, and the average annual power outage time of users is 18.43 hours

electric power joins hands with the future

the chapter of electric power outlook prospects the rapid promotion and application of 300000 tons of intelligent technology achievements represented by intelligent electricity in the energy field in the future

when smart electricity is basically completed, it will promote China's power system to become the world's largest power system with the strongest resource allocation ability and the highest degree of intelligence, covering all links of power generation, transmission, transformation, distribution, power consumption and dispatching. It is of great significance for adjusting the energy structure, energy conservation and emission reduction, and coping with climate change. The key is that smart electricity is the central nerve to promote people's lives to be better

the white paper predicts that by 2020, the power outage time of urban users in China will not exceed 4 hours per household, and that of rural users will not exceed 17 hours per household. The national installed power generation capacity reached about 1.935 billion kw, with an average annual growth of 5.8%; The national 110 kV and above lines have reached 1.76 million kilometers, and Sanhua synchronous power has formed a five vertical and six horizontal main frame. The total installed capacity of non fossil energy power generation is 715million kW, accounting for 37% of the total installed capacity; The national wire damage rate fell to 6.3%; Compared with 2010, the emission intensity of sulfur dioxide and nitrogen oxides from coal-fired power plants in China decreased by 35.4% and 41% respectively in 2015
