我国实现从数字变电站到智能变电站的重大突破,近期我国相继建成投产了四川110 kV北川智能变电站、青岛220 kV午山智能变电站等7座智能变电站,实现了从数字变电站到智能变电站的重大突破。“十二五”期间,国家电网将投资5 000亿元,建成连接西部大型能源基地与东部主要电力负荷中心的“三横三纵”特高压骨干网架和13回长距离支流输电工程,初步建成核心的世界一流的坚强智能电网。建设以特高压为骨干的坚强智能电网是中国经济社会发展和能源禀赋特点的需要。我国能源呈逆向分布:三分之二的煤炭资源和水电资源集中在北方和西南部,陆地风能集中在西北部地区,而三分之二的能源消费集中在中东部地区。
China has achieved a major breakthrough from digital substation to smart substation. Recently, China has successively completed and put into production seven intelligent substations such as Sichuan 110 kV Beichuan Smart Substation and Qingdao 220 kV Yushunshan Intelligent Substation, realizing a major breakthrough from digital substation to smart substation. During the 12th Five-Year Plan period, the State Grid will invest 500 billion yuan to build “three horizontal and three vertical” UHV backbone grids and 13 long-distance tributaries that connect the major western energy bases and the eastern major power load centers Transmission project, initially built a core world-class strong smart grid. Building a strong smart grid with UHV as its backbone is a need of China’s economic and social development and energy endowments. China’s energy sources are in reverse distribution: two-thirds of coal and hydropower resources are concentrated in the north and southwest, land wind energy is concentrated in the northwestern region, and two-thirds of energy consumption is concentrated in the central and eastern regions.
