    Overview of the focus on the development of the next five years, China's power grid

    Is the world's highest voltage level, the largest Chinese power grid, the next five years will be an annual investment of about 500 billion yuan scale toward "Resolving the coal transported tensions and contradictions, to adapt to the construction of large-scale energy base and a large number of clean energy delivery elimination satisfied the requirements to meet the economic and social development and the people living electricity demand "direction, will initially build a world-class power grid by 2015.


    The 7th meeting of the State Grid Corporation of annual work conference revealed four priorities for the next five years, the rapid development of China's power grid: UHV, smart grid, a new round of rural power grids, internationalization.

    Built UHV backbone network


    In the past five years, China fully grasp the the UHV transmission core technology and a full set of equipment manufacturing capacity, have been built and put into operation three large-scale, long-distance power transmission UHV AC and DC transmission lines, the field of science and technology in the world grid " Created in China "and" China lead.


    Chinese Academy of Engineering, honorary dean of the State Grid Electric Power Academy of Sciences Xue Yu wins on this evaluation: UHV technology is a major change in the world energy transport way of the human efficient, green, safety use energy far-reaching impact, with space technology, like high-speed rail technology, China's 11th Five-Year Plan 'period to make a significant contribution to the development of the world's industrial. "


    The development of UHV 'second five' grid development a top priority. "Said Liu Zhenya, general manager of the State Grid Corporation of the next five years will invest over 500 billion yuan to build" three vertical and three horizontal "UHV AC backbone network and 11 UHV DC transmission project, the line length will reach 40,000 kilometers, the formation of the coordinated development of a strong grid AC-DC grid.


    Accelerate the construction of the base of the large western coal-fired power, hydropower, nuclear power and wind power, solar power, renewable energy, it is expected that by the end of 2020, the scale of the need for long-distance transport of electricity to more than 400 million kilowatts.


    The main way to solve the western energy sent to the eastern load centers is UHV transmission lines. According to reports, the next five years to build "three vertical and three horizontal" UHV grid wind power in Inner Mongolia, Shaanxi, Hebei, coal by three longitudinal UHV channel sent to the north, central and eastern China; northern coal hydropower electricity and southwest, through the the the three horizontal UHV channel sent to North China, Central China and the Yangtze River Delta region.


    January 6 this year, the world's first two years of operation UHV transmission lines southeastern Shanxi - Nanyang - Jingmen line expansion, completed by the end of this route of transmission capacity will be expanded to double the 5 million kilowatts, can be extremely The large tensions ease in central China coal transported. In addition, this year there Huainan - XiMeng - Nanjing, and a number of UHV project is expected to be approved by the State to start the construction.

    Basically built strong and smart grid


    January 4, China's first use of IOT technology Intelligent Substation - 220 kV West Jing intelligent substation in Wuxi, Jiangsu put into operation, marking China's large-scale construction of smart grid.


    Smart Grid is the key to a low-carbon development in the ascendant in the world. Liu Zhenya said: "In the next five years, China has accelerated the construction of the critical period of strong and smart grid."


    State Grid Corporation of planning is basically completed by 2015 with a strong smart grid information technology, automation, interactive features, the formation of the North China, Central China, East China, northwest, northeast power grid by the end of the sending end of the three synchronous network, the grid resource allocation, economic efficiency, the level of safety, scientific and technological level and the level of intelligence have been fully upgraded, initially built a world-class grid.


    Liu Zhenya said, the focus of the 2012 smart grid construction, the completion of the two batches of pilot projects to speed up the promotion of intelligent substation, distribution automation, power fiber to the home and other key projects in Beijing, Yangzhou and other places to build a number of demonstration projects, and the promotion of application of the 50 million smart meters.


    Use the terminal for the advantage of the grid, national grid strongly promote the construction of electric vehicle charging facilities in 2010, all 26 provinces within the business scope municipal government signed the agreement of cooperation in the construction of electric vehicle charging facilities, and full completion of the beginning of the development of the new 75 charging stations and 6,029 charging pile plan.


    "Mode of operation of electric vehicles and charging station construction companies and grid development is of great significance." Liu Zhenya said this year the national grid for electricity main inserted charge and supplemented, centralized charging, unified distribution "business model, speed up the charge for the layout and construction of the power station. Filling station is expected throughout the year will be built 150 electric vehicle charging electric service network and built in Beijing, Hangzhou, Tianjin, Hefei, Nanchang and other cities.

    The implementation of a new round of rural power grids


    Recently held a State Council executive meeting decided to implement a new round of rural power grids upgrade project in the 12th Five-Year "period. This project will allow 5.3 million without electricity the rural population have access to electricity, so that the all good rural population with electricity. Including comprehensive transformation of the rural power grid of the unmodified; transform, but there are still insufficient power supply capacity and reliability of power supply lower rural power grid implementation of the upgrade; and to achieve the various urban and rural electricity Tongwangtongjia .


    Sun Jichang, within five years, the national grid will be arranged 410 billion yuan for rural power grids, coupled with China Southern Power Grid invested about 100 billion yuan, it is expected that the country will have more than 500 billion yuan investment in this 12 years later, director of the national grid rural power after another round of rural power grid renovation project.


    Sun Jichang five years, rather than in July last year, the National Energy Board in the nationwide upgrade rural power grids work conference concentrated around three years time, the investment over 200 billion yuan to complete a new round of rural power grids ", has explained that because grid construction approval cycle, but also to be consistent with the usual five-year plan in order to facilitate planning.


    Since February last year, the central "Document" explicit proposal to pay close attention to the implementation of a new round of upgrading rural power grid construction start, the grid sector started to develop a plan and goal of the project, construction of key. With the planning were introduced and funding gradually put in place, around a new round of rural power grid renovation project in November last year have started.


    To Sun Jichang, 2011, the central government allocated 12 billion yuan capital was issued in November, the national grid of 9.42 billion yuan, plus bank loans and self-financing, national grid this year, investment in rural power grids capital of 622 billion yuan The investment focus is not yet over rural power grids in the region, giving priority to the agricultural production of electricity, as well as to carry out upgrading rural power grid model building to address the outstanding problems of the rural power grid "strangle hold" low-voltage ".

    "Going out" to participate in the competition in the international grid


    State Grid Corporation of investment in fixed assets of about 300 billion yuan per year in the past were mainly channeled to the country, a very small proportion of the international market. But with the the UHV technology breakthrough innovation and the success of the grid and transmission companies acquired in the Philippines and Brazil, the State Grid Corporation of international fame.


    Five years from now, the company is fully completed period of opportunity for international enterprise. "Liu Zhenya was first proposed in the annual work conference, to seize the Central favorable opportunity to encourage foreign investment, accelerate the pace of international business strategy layout.


    Fortune 500 companies ranked eighth grid "giant" will be high quality assets on the grid mergers and acquisitions, UHV engineering applications, the acquisition of mineral resources, the total package of international engineering, electrical equipment output business focus on the development of international business.


    "To further consolidate and expand the results of the Philippines, Brazil and other international operations, speed up to promote business development in Africa, Asia, Europe, North America and other regions, for as soon as possible to achieve a major breakthrough in the international operations." Liu Zhenya, determine the five-year goal of the State Grid Corporation is a "the initially built world-class enterprise"


    The national grid to the end of last year to $ 989 million to acquire and take over the operations of seven Brazilian power transmission concession. Liu Zhenya said that the successful acquisition of an important bargaining chip Brazil fancy UHV technology. This year, the State Grid will promote the application of the 800 kV HVDC transmission project in Brazil's large hydropower. In addition, this year the national grid will be carried out with the United States, Russia the UHV cooperation, and expand in Africa, India, North America and other places in the power investment market.
