新华社武汉７月１９日电（记者吴植）１９日，我国“１０００千伏晋东南－南阳－荆门特高压交流试验示范工程”首次进行４００万千瓦大功率南电北送试验并取得成功。它标志着我国首条特高压输电线路已全面达到设计能力，能够实现华中、华北两大电网之间的大功率水火电互济。

    The xinhua news agency on July 19, wuhan（Reporter WuZhi）19，Our country“1000 kv southeast shanxi-nanyang-jingmen uhv communication experiment demonstration project”For its first 4 million kw high-power electric north to south test and succeed。It marks the first in China uhv transmission lines are already full to meet the designed capacity，Can realize the central China、North China power grid of between two high power fire and water electricity each other aid。

    晋东南－南阳－荆门特高压线路起于山西长治，止于湖北荆门，全长６４５公里，它也是世界上首条正式投入商业运行的特高压线路。线路投运３年多来，主要用于华北火电南送，大大缓解了化石能源匮乏的华中地区电力供应紧张的局面。但该线路平时的电力输送功率为２００万千瓦左右，较设计能力尚有差距。

    Southeast shanxi-nanyang-jingmen uhv line up in shanxi changzhi，Stop in hubei jingmen，The 645 km，It is also the world the first officially put into commercial operation of the ultra-high voltage circuit。Line 3 years to put into operation，Mainly used for thermal power south north China send，The fossil energy greatly alleviate the lack of central China power supply tense situation。But the line at ordinary times the power transmission power for 2 million kw or so，There is a gap between the design ability。

    按照国家电网公司的部署，该线路已于去年１１月成功进行４００万千瓦大功率北电南送试验，此次大功率南电北送试验从１９日８时开始，至１６时结束，其间输电功率峰值达到４００万千瓦，并持续３个小时。来自华中地区的大量清洁水电能源搭乘着这条世界最高等级的“电力高铁”被送至华北电网，为河南、山西等地缓解了迎峰度夏供电难题。此举不仅降低了华北的煤炭消耗，也提高了夏季丰水期华中水电的利用率。

    According to the national grid deployment，This line has in November of 4 million kw power nortel successful south send test，The high power electric north to south test from 19 at 8 start，To 16 ended when，Meanwhile transmission power peak reach 4 million kilowatts，And last for three hours。From a large number of central China clean water and electricity energy on the highest grade of the article this world“Power high iron”Sent to north China grid，In henan、Shanxi etc easing summer peaks power supply problems。This not only reduces the north China coal consumption，Also improves the utilization rate of central China hydropower summer rainy season。

    湖北省电力公司有关负责人说，此次大功率试验在国内外没有充分的经验可循，若准备不充分，大负荷压力可能会导致华中、华北两大电网解列，因此电力部门制定了详尽的保电方案，全面开展了线路隐患排查工作。湖北超高压输变电公司、湖北省电力试验研究院、中国电科院和国网电科院等多家科研单位都参与到了试验过程中，以求为今后我国特高压设备研究储备经验和数据。

    Hubei electric power company officials said，The high power test both at home and abroad and not fully experience to be followed，If prepare adequately，Big load stress may result in central China、North China grid solution two columns，So power department to make a detailed scheme of the electricity，Overall the circuitry hidden trouble work regularly。In hubei ehv transmission company、Hubei electric power test research institute、China's electricity science institute and priorities of electrical science and companies are involved in scientific research units to test process，For our country in the future, high pressure equipment research experience and data reserves。

    晋东南－南阳－荆门特高压工程２００９年１月正式投运，标志着我国在远距离、大功率、低损耗特高压输电核心技术和设备国产化上取得重大突破。去年，华北火电通过该线路送华中１６４亿千瓦时，替代运煤５３０万吨；华中水电送华北９３亿千瓦时，节约用煤３００万吨，减排了大量二氧化碳。

    Southeast shanxi-nanyang-jingmen uhv engineering in January 2009 formally put into operation，Marks in the distance in our country、power、The low loss uhv transmission core technology and equipment based on significant breakthrough。Last year，North China through the lines to send the central China power 16.4 billion KWH，Alternative carry 5.3 million tons；The central China hydropower send north China 9.3 billion KWH，Save with coal 3 million tons，A lot of carbon dioxide emissions。
