UHV expansion of the strategic value of energy

   As a "second five" start the construction of UHV projects, southeastern UHV demonstration project connecting central, north of energy a major thoroughfare, the value of the expansion project is very prominent.

    Recently, the reporter went to the southeastern UHV substations UHV interview with the construction of the expansion project. At the construction site, the station Ai-Min Yang saidglue gun : "No matter from which point of view, the expansion projects are too important."

    Significance of the initial demonstration project

    Reporters learned that UHV has been national and local attention. At the national level, the construction has been written into the UHV national "five" Plan, which means that the UHV building a national strategy, the development of ultra-high voltage is not a business thing, but closely linked with national economic construction. From the local level, in early 2011, Shanxi, Shaanxi, Xinjiang and other provinces at least six governmentglue stick work report, direct the development of UHV ideas; province "two sessions", CPPCC Hunan first document is directed at the "second Five "energy security system, the construction of high voltage lines as an important option.

    Why this happens? On January 6, UHV construction mobilization meeting on the expansion project, the State Grid Corporation, party secretary Liu Zhenya, then perhaps the answer. He said: from the basic national conditions, only accelerate the construction of high voltage power grid, the promotion of large coal, large hydropower, large nuclear power, large-scale clean energy base of the intensive development of energy resources in a wider scope to achieve the optimal allocation, in order to protect the energy can be continuous supply, promote energy conservation, a fundamental solution to the economic development problems of energy and power constraints, to achieve energy and power industry's scientific development.

    "Second five" special high-pressure build into the fast lane, while the UHV expansion project as a "1025" period construction of the first UHV project, the importance of the natural multiplication. State Grid Corporation of party members, deputy general manager Zhengbao Sen said: "The expansion project is the 'second five' special high-voltage power grid construction projects started, construction and operation of UHV will play an important role model."

    Reflected in a model, it will further validate the UHV high-capacity, long-distance transmission capacity. In the southeastern station, Ai-Min Yang stood before a group of huge transformers, this is a new main transformer, the line transmission capacity expanded to 500 million kilowatts. Doubling the transmission capacity and improve network capacity and resource allocation level of security and stability.

    Another manifestation of a model, which further promoted the UHV technology innovation. Expansion of the world's first application of UHV series compensation device, enrich and improve the special high-voltage transmission technology and equipment. China Electric Power Research Institute Technical experts said that the application of series compensation devices, can significantly increase the transmission capacity of UHV, enhance system stability, improve the operating voltage and voltage distribution along the route, is to ensure the transmission capacity of 5 million kilowatts with a prerequisite .

    Project to open a good head start, will promote the construction of other projects, and ultimately by the large range of optimal ultra-high voltage role in resource allocation.

    Energy channels of the economic "benefits"

    If the view from the national level to regional level, for example, works along the lines of Shanxi, Henan and Hubei provinces, we find that the expansion project for the provinces and North China, Central China brought many economic "welfare."

    Expansion project for Shanxi, is the important starting point for economic transformation.

    March 1, Vice Governor of Shanxi Province, Ren Yun-thick trek to the southeastern stations, expansion of construction inspection. He said he hoped to speed up the power point Changzhi City planning and construction of in situ conversion of coal to deepen integration of coal resources, and promote national resources are being implemented in Shanxi-based economy development of a comprehensive reform.
