中国电网自诞生100多年来,从无到有,从小到大,从弱到强,一级级跨越,取得了举世瞩目的成就,已进入世界先进国家行列。目前,中国的电网规模已居世界首位,并拥有世界最高的交、直流输送电压等级。在电网规模显著扩大的同时,电网技术含金量也在不断提高,特高压交直流输电、柔性交直流输电、智能电网技术等正蓬勃发展。在追求电网安全可靠运行的同时,中国也关注供电的高效性、互动性,以及智能化、信息化、互联互通的发展趋势。
Since its birth 100 years ago, China Power Grid has made remarkable achievements in everything from scratch, from small to large, from weak to strong and across a class and has entered the ranks of the most advanced countries in the world. At present, China has the largest power grid in the world and possesses the world’s highest AC and DC transmission voltage levels. While the scale of power grid has been significantly expanded, the gold content of power grid technology is also constantly increasing. UHV AC and DC transmission, flexible AC and DC transmission and smart grid technologies are booming. While pursuing the safe and reliable operation of power grids, China is also concerned about the efficiency and interactivity of power supply as well as the development trend of intelligence, informationization and interconnection.
