Xiaolangdi Hydro Project
Xiaolangdi Hydro Project, a large modern water conservancy project, is located on the lower reaches of the Yellow River, 40km north of the ancient city of Luoyang in central Chinas Henan Province. As a key Chinese national project, Xiaolangdi Hydro Project is the largest of its kind on the Yellow River and second only to the Three Gorges project on the Yangtze River. It consists of a 1617m-long, 154m-high dam, silt-discharge channels and underground generating units. Preparatory work began in 1991. Main orders were placed in September 1994. One of the landmark events of the project involved diverting the Yellow River. This took place on 28 0ctober 1997 and became a national occasion. The dam received state approval and started storing water in October was connected to the grid in January in 2000 and the whole projed was completed in 2001.
在河南省洛陽以北40千米處，一座現代化的特大型水利樞紐，小浪底水利樞紐工程，屹立在黃河最後一段峽谷之上。小浪底水利樞紐工程現爲黃河上最大的水利工程，僅次於長江三峽水利樞紐工程，屬中國國家重點項目。小浪底工程由攔河大壩（壩頂長度1617米，壩高154米）、泄洪建築物和引水發電系統組成。小浪底工程1991年9月開始前期工程建設，1994年9月主體工程開工。1997年10月28號大壩順利完成截流，1999年10月經政府許可開始蓄水。2000年元月首臺機組併網發電，2001年底主體工程全面完工。Xiaolangdi Project, designed to trap and flush sediments on the lower reaches of the Yellow River, could cope during the summer flood season. Xiaolangdi Hydro Project has been subjected to devastating Yellow River floods and has played an irreplaceable role in the agricultural area addition, the l,836mw Xiaolangdi Project is generating 5. 1 billion kwh of electricity a langdi is a multi-purpose project for dredging, flood control, ice control, industrial and municipal water supply and hydroelectric is the key project of Yellow River Projects, considered as one of the most complicated and challenging hydroelectric projects in the world.
黃河小浪底水利樞紐工程的建成有效地控制了黃河下游沉積物，基本解除黃河下游凌汛威脅。小浪底水利樞紐工程不僅時刻保障着中國母親河的歲歲安瀾，也爲沿線農業地區發揮着不可取代的關鍵性作用。除此之外，小浪底電站總裝機183.6萬千瓦，年平均發電量51億千瓦時。小浪底水利樞紐工程是黃河干流上的一座集減淤、防洪、防凌、供水灌溉、發電等爲一體的大型綜合性水利工程，是治理開發黃河的關鍵性工程，被中外水利專家稱爲世界上最複雜的水利工程之一，是最具挑戰性的工程。
