Шаблон:Infobox dam The Fengtan Dam is an arch-gravity dam on the You River, located Шаблон:Convert southeast of Zhangjiajie in Hunan Province, China. The purpose of the multi-purpose dam is flood control, irrigation, power generation and navigation. The dam has a power station with an installed capacity of 800 MW and provides water for the irrigation of Шаблон:Convert. Construction on the dam began in 1970 and the first generator was operational in 1978. All four of the original generators were operational by 1979.[1] A power plant expansion project began in 2001 and in 2004 two additional 200 MW generators were commissioned.[2][3]
Design
The Fengtan is a Шаблон:Convert tall and Шаблон:Convert long (at the crest) arch-gravity dam. Its base arch length is Шаблон:Convert and the dam has a curve radius of Шаблон:Convert. The base width of the dam is Шаблон:Convert. The crest sits at an elevation of Шаблон:Convert above sea level while normal reservoir elevation is Шаблон:Convert. The dam sits at the head of a Шаблон:Convert catchment area and withholds a reservoir with a capacity of Шаблон:Convert. The dam's spillway is located on its downstream face and consists of 13 chutes controlled by radial gates. Six of the chutes have their flip buckets mid-way on the face of the dam while the seven others are on the lower portion. The original power house is located within the left side of the dam near the abutment and contains four 100 MW Francis turbine-generators. The turbines are afforded a rated hydraulic head of Шаблон:Convert and are each supplied water via a Шаблон:Convert diameter penstock. On the dam's right bank, there is a 50-ton boat lift which is also used to move lumber as well.[4][5]
