On July 26, 1882, China's first electric light was lit on the Shanghai Bund. Until July 26 of this year, China's electric power industry's first "electricity theme day" was held in a grand event. China has already gone through a full 130 years of history of electricity.
To commemorate such a historical moment, on the day of the event, the CEC released a book entitled "The Value of Electricity." This is China's first white paper on the value of the power industry. Through the pages of the book, we review the history of electricity along with the rejuvenation of the Chinese nation, give an overview of the extraordinary value of electricity created in today's society, and look forward to a bright future for electricity carrying. At this point, by holding the "value of electricity" in your hand, you will feel its heavy weight.
Power cognition power change the world power industry development process is a microcosm of the history of national economic development. Since the beginning of reform and opening up, especially since the beginning of the 21st century, China's power industry has made great achievements and progress in both the scale of development and the quality of development, from large generating units, ultra high voltage, and nationwide networking to green power generation, UHV, and smart grids. Change in the new stage of development.
The book “The Value of Electricity†shows that the scale of China’s electric power installation has reached a new level. From 2002 to 2011, the annual growth rate of power generation in the power industry reached 12.4%; the installed capacity and power generation of the country’s electric power were from 357 million kilowatts and 16,500 respectively. Billions of kWh were increased to 1.063 billion kW and 4.73 trillion kWh. As of the end of 2011, the scale of China's power grid ranks first in the world for three consecutive years. The loop length of 220 kV and above transmission lines is 475,000 km, the public transformer capacity of 220 kV and above is 2.208 billion kVA. The maximum transmission voltage level has been continuously increased, and 750 kV transmission lines and 1000 kV UHV have been built successively. AC, ± 800 kV UHVDC transmission lines. By the end of 2011, with the exception of the Taiwan region, China’s provincial power grids will be interconnected by AC and DC, and a nationwide network will be formed. The rapid development of the electric power industry has fundamentally lifted the bottleneck of electricity on the development of the national economy, effectively supported and promoted the growth of the national economy, and basically met the increasing demand for electric power by people's living standards.
In recent years, driven by the globalization of economic development, China Power International has become increasingly active in international cooperation among governments, industries, and enterprises. Large-scale power companies promote internationalization strategies and international energy under the guidance of the overall national energy strategy. Cooperation, expansion of international business, creation of comprehensive value, and global counterparts to jointly meet the challenges of sustainable development, and actively participate in international engineering contracting, foreign investment, equipment and technology import and export, and acquisitions and other fields.
Electric power creates value for electricity According to the book “Value of Electric Power,†electric power development supports the rapid growth of China’s national economy with an average of nearly 10% for more than 30 consecutive years. From the early days of reform and opening up to the suffering of frequent power outages, the average annual power outage time in current cities is less than 8 hours, and the average annual outage time in rural areas is less than 18.43 hours.
The power industry also plays a very important role in ensuring strategic energy security. In China's railway traffic, coal transport accounts for about 50%, of which electricity is mainly coal. Adhering to coal transportation and power transmission simultaneously, while continuing to strengthen the construction of railways and other transportation, we will vigorously accelerate the development of transmission, build UHV power grids, and improve the large-scale and long-distance power transmission capacity of the power grid. This is one of the strategic options for optimizing and adjusting China's energy structure and layout.
The "Twelfth Five-year Plan Outline for the National Economic and Social Development of the People's Republic of China" released in March 2011 puts the smart grid as one of the key tasks for energy development. Chinese power grid companies have formulated plans for the construction of smart grids, implemented pilots, formulated standards, and achieved a number of major technological achievements in the areas of smart energy meters, large-capacity energy storage batteries, new energy generation and grid-connected control, making China Smart Grid The development of the world is at the forefront of the world.
China's power industry has also made unremitting efforts in dealing with climate change and strengthening energy conservation and emission reduction. In 2011, the line loss rate in China was 6.37%, which was a drop of 0.69 percentage points from 2005, and continued to be the advanced level in countries with the same power load density conditions. As of the end of 2011, the capacity of the flue gas desulfurization units that have been put into operation nationwide has reached 630 million kilowatts, which is nearly 11 times that of 2005.
The power quality provided by China's power grid companies is also constantly improving. In 2011, the reliability of power supply for users of 10 kV power supply systems in Chinese cities was 99.920%, and the average annual power outage time was 7.01 hours. The reliability of electricity supply for rural users is 99.790%, and the average annual power outage for users is 18.43 hours.
Power Outlook Power Hand in Hand In the next 2020, China's heavy industry is expected to account for 82% of the industry, and urbanization is expected to reach 56%. In 2010, China’s population totaled 1.36 billion people, and by 2030 it is expected to reach a peak of 1.47 billion people. With the expansion of the national economic and social development needs, the level of modernization of the power industry will also be significantly improved.
In the near future, the achievements of smart technologies represented by smart grids will be rapidly applied in the energy sector. When the smart grid is basically completed, China's power system will be promoted to become the world's largest and most resource-configured and highest-intelligence power system, covering all aspects of power generation, transmission, substation, power distribution, electricity use, and dispatch. Energy structure, energy conservation and emission reduction, and response to climate change are of great significance. The key is that the smart grid is a “central nervous system†that makes people’s lives better.
The future grid will become a more reliable grid. It is estimated that the time of power outage for urban users will not exceed 4 hours per household in 2020, and that rural users will not be out of power for 17 hours per household.
The future grid will become a more efficient grid. It is estimated that by 2020, the country’s installed power generation capacity will reach 1.935 billion kilowatts, an average annual increase of 5.8%; the nation’s 110 kilovolt and above lines will reach 1.76 million kilometers, and the “Three Chinas†synchronous power grid will form the “five vertical and six horizontal†main grid.
Future electricity will become cleaner electricity. It is estimated that the total installed capacity of non-fossil energy generation in 2020 will be 715 million kilowatts, accounting for 37% of the total installed capacity; the rate loss of the national power grid will decrease to 6.3%; compared with 2010, China's coal-fired power plant will produce sulfur dioxide and nitrogen oxides in 2015 The emission intensity dropped by 35.4% and 41% respectively.
