新华社宜昌７月２６日电 (新华社记者刘紫凌、冯国栋、李思远)２４日晚至２５日，世界最大水利枢纽工程——三峡工程，经受了一次历史罕见的特大洪峰考验。目前，洪水过境，荆江安然。

    The xinhua news agency yichang July 26 (The xinhua news agency LiuZiLing、FengGuoDong、LiSiYuan)24 days late to 25，The world's largest water control project engineering, the three gorges project，Had had a history of extreme flood peak rare test。At present，The flood of transit，River enron。

    ２４日晚８时，长江４号洪峰流量达到每秒７．１２万立方米，是三峡工程蓄水成库９年迎来的最大洪峰，也是长江３０年来遭遇的最大洪峰。通过科学调度，三峡枢纽及时削峰拦洪，使大坝下游主要站点水位涨幅保持在可控范围内。

    24 8 p.m，The Yangtze river 4, 71200 cubic meters per second peak flow，The three gorges project is water into nine years in the biggest library flood peak，The Yangtze river is the biggest flood peak in 30 years。Through the scientific control，The three gorges project timely cut LanHong peak，Makes the main site or keep water downstream manageable。

    在洪峰抵达三峡水域前，借助洪水带来的高水头和大流量，三峡工程３２台巨型发电机组持续１２天实现满负荷运行，发电量超过６０亿千瓦时。通过电网调配，这些电量对缓解夏季用电紧张起到积极作用。

    In the three gorges waters flood peak arrived before，With the flood bring high water head and large flow，The three gorges project and a giant generator for 12 days realize full load operation，More than 6 billion kilowatt hours of electricity generating capacity。Through the grid deployment，These power to alleviate the power played a positive role in the tension。

    这不是中国第一次在三峡工程防洪调度中实现“洪水资源化”。

    This is not the first time China in the three gorges project is realized in flood control operation“Flood resources”。

    数据表明，２００９年，仅在长江汛期的防洪调度中，三峡电站就增发５亿多千瓦时电量；２０１０年，长江来水偏丰，汛期遭遇几轮洪峰，最大峰值超过７万立方米／秒。通过科学进行防洪调度，三峡电站２０１０年增发６３亿千瓦时电量；即便是在来水偏少的２０１１年，通过多次对汛期中小洪水进行拦蓄，三峡电站当年也增发电量２８亿千瓦时。

    Data show that，2009 years，Only in the Yangtze river flood season in the flood control operation，Three gorges hydropower station is by more than 500 million kilowatt-hours power；2010 years，The Yangtze river water partial abundantly，Several rounds of flood peak in flood season，Maximum peak value more than 70000 cubic meters per second。Through the science in flood control operation，Three gorges hydropower station in 2010 by 6.3 billion kilowatt hours of electricity power；Even in the 2011 years scarce water，Through many times during the flood of small and medium for use，In the three gorges hydropower station is also generating capacity of 2.8 billion kilowatt-hours。

    负责三峡工程运行管理的中国长江三峡集团公司董事长曹广晶说，成功应对洪水，依靠的是“科学调度”和“精心运行”。

    Responsible for the three gorges project operation management of China Yangtze three gorges group company chairman CaoGuangJing said，Successfully meet the flood，Depends on the“Scientific control”and“Elaborate operation”。

    ２５日，参与三峡调度的工程师赵云发对记者说，三峡工程的总库容是３９３亿立方米，在世界上排名第２２位。由于长江汛期来水量大，所以三峡工程无法像世界上其他大型水库那样，一次性拦蓄几年甚至数十年的洪水。

    25，Participate in the three gorges scheduling engineers ZhaoYunFa told reporters，The three gorges project is a total capacity of 39.3 billion cubic meters，The number 22 in the world。Due to the amount of the Yangtze river flood season，So the three gorges project will not be like the rest of the world that large reservoir，One-time use for years, or even decades of flooding。

    在正常蓄水位１７５米至防洪限制水位１４５米间，三峡水库有２２１．５亿立方米的可用防洪库容。２２１．５亿立方米，相比世界大型水库，这个库容更是有限。因此，科学调度显得尤为重要。

    In normal storage level 175 meters to flood control limit water level between 145 m，The three gorges reservoir of 22.15 billion cubic meters of flood control capacity available。22.15 billion cubic meters，Large reservoir than world，This capacity is limited。so，Science scheduling is particularly important。

    每年长江汛期到来之前，水位要消落至１４５米，腾出足够库容来迎汛防洪。汛后再蓄水至１７５米，用于发电和生态补水。在１４５米－１７５米间，通过科学调度，洪水可以最大限度地资源化，造福人民。

    Each year before the arrival of the Yangtze river flood season，Water levels to fall to 145 meters away，Have enough to meet the capacity of the design flood control。Xun again after the water storage to 175 m，Used for power generation and ecological filling water。In the 145 m-175-m rooms，Through the scientific control，Water can maximize the comprehensive utilization，Benefit the people。

    今年汛期，为科学调度三峡工程，长江防汛部门共进行２８次会商，向三峡枢纽下发了１３次调令，“指导”三峡工程驾驭洪水。

    During this year，For scientific control in the three gorges project，The Yangtze river flood control department a total of 28 times in consultation with，For the three gorges project were issued a 13 times，“guidance”The three gorges project flood control。

    “三峡工程的气象、径流预报手段已有很大提高，预见期增长，为防洪调度提供了保障。”中国科学院院士陈祖煜说。调度好汛期洪水，不仅可以带来巨大的经济效益，也可以发挥巨大的社会效益。

    “The three gorges project、Runoff forecast has greatly improved means，Predicted growth period，For flood control operation to provide the safeguard。”Academician of the Chinese academy of sciences ChenZuYu said。Scheduling good flood periods，Not only can bring huge economic benefits，Can also play a huge social benefits。

    ２０１０年，三峡工程尝试借助汛末小型洪水，适度抬高水库水位，并首次将水库水位蓄至１７５米“终极”蓄水位。

    2010 years，The three gorges project at the end of the design tries to small floods，Moderate reservoir water level up，And for the first time, storage reservoir water level to 175 m“ultimate”Storage level。

    ２０１０年，长江中下游发生５０年一遇大旱，三峡工程启动应急补水调度，将２０１０年拦蓄的来水释放至下游干旱地区，有效抬高了河道水位，保障了沿线地区人畜饮水安全。

    2010 years，The middle and lower Yangtze happen in a severe drought during the 50 years，The three gorges project start emergency hydrating scheduling，Will reduce the release of 2010 coming to downstream dry regions，Effective drive up river water level，Guarantee the safety of drinking water in the region along the human and livestock。

    曹广晶说，洪水就是资源，三峡工程作为一个特大“治水工程”和“民生工程”，已经由过去的“孩子”变为“成人”，可以全面担负使命，发挥四项功能，实现综合效益。

    CaoGuangJing said，The flood resources is，The three gorges project as a big“Water engineering”and“People's livelihood engineering”，Have in the past“children”into“adult”，Can fully responsible for the mission，Play four function，To realize comprehensive benefit。
